Publisher’s Letter

Recognizing success in the asphalt pavement industry

As a former reporter, I’ve always had a soft spot for a good story. And even though I’m no longer in the news business, one of the most satisfying parts of my current job representing the asphalt pavement industry in California is telling success stories.

These stories come in many different forms. Sometimes they are company profiles, chronicling the achievements of longtime member companies, many of which are celebrating milestones for longevity and boast an impressive track record of successful projects. Then there are the professional milestones, such as when industry leaders ascend to important positions of prominence, either in their companies or in the leadership of our association. We may also report on retirement of someone you may know, or should, after a long and rewarding career.

Of course, we also mark the passing of important industry giants by reminding everyone of their life and legacy of service, which are an inspiration to us all. These stories are handled with the special care and reverence they deserve. Our story in this issue about the life and legacy of Majid “Mo” Mojini is but one example.

Another type of recognition story arises when collaboration between the asphalt pavement industry and the public sector results in positive outcomes for our fellow Californians. These are a joy to write. One example is the work between Caltrans and CalAPA members to develop a new pavement smoothness specification. Over many meetings the pros and cons of various approaches were thoughtfully examined, and an innovative approach was developed. Caltrans leadership recognized the effort by handing out plaques to all involved. We put the story on the cover of this magazine.

Recognition doesn’t necessarily need to include a plaque or certificate — just publicizing it is another form of highlighting a good story. That was the case with the Caltrans-industry collaboration that resulted in the Joint Training & Certification Program for materials technicians. The program has attracted notoriety for elevating the skill of technicians, reducing errors and conflicts, and saving money. Elected officials, including former Sen. Jim Beall, D-San Jose, author of the landmark SB1 road-repair legislation, and Assemblyman Patrick O’Donnell, D=Long Beach, a member of the Assembly Transportation Committee, were among those elected officials who toured the JTCP facilities at Cal State Long Beach and San Jose State University to see for themselves this amazing program. That story graced the cover of this magazine as well.

The current issue of this magazine features another nod to recognition, this time for the innovative Long-life Asphalt Pavement design strategy in California, which is piling up national awards for innovation. Our last major story on this topic, which appeared in this magazine in 2013, outlined the promise of this design strategy, which was still being developed and evaluated. Now it has gone mainstream, including racking up several awards by the Asphalt Pavement Alliance, a CalAPA partner, and favorable evaluations by university researchers. In preparing the story for this issue, there clearly was not room to name the many people to contributed to this important achievement. But I would be remiss if I didn’t single out an amazing ambassador, Asphalt Institute Senior Regional Engineer Bob Humer, who is a walking storehouse of knowledge on the topic (and many others related to asphalt pavements). He has a credibility earned over many years for always putting sound engineering principles and research at the forefront of any discussion of asphalt pavements.

A good story always has a good ending, but in the case of these success stories and others not yet written, they will continue to be a regular feature of this magazine. It’s my privilege to play a small part in helping tell them.

National recognition for innovative Caltrans design strategy delivering asphalt pavement projects that last 40 years and longer

By Russell W. Snyder

Chris Handley with Tullis Inc. speaks with pride when he recalls his company’s work on a prominent Long-Life Asphalt Pavement project on Interstate 5 in the North State.

“It’s a great strategy, and the taxpayers are really getting a better bang for the buck,” he said in a recent interview with California Asphalt magazine. Tullis, a CalAPA member based in Redding, was the prime contractor and also produced the asphalt for the innovative project on Interstate 5 in the Red Bluff area.

“It required us to obtain recycled asphalt pavement from the project, do mix designs, and work collaboratively with Caltrans and the University of California Pavement Research Center,” Handley said. “Some of the testing was really new then to industry and to Caltrans, so we partnered with them and the UCPRC and came up with a stellar mix. It’s performed flawlessly for more than 10 years now.”

The 14.5-mile project received national recognition earlier this year from the Asphalt Pavement Alliance with a “Perpetual Pavement by Conversion” Award, the most prominent of three projects nationally in the category. The Asphalt Pavement Alliance is a national organization supported by the National Asphalt Pavement Association, the Asphalt Institute and state asphalt pavement associations, including CalAPA. It was just the latest recognition for

the project, which also won in the “Transportation Innovations” category of the 2015 Caltrans “Excellence in Transportation Facilities Award.” It’s also referenced as a “benchmark mix with good performance” in a recent UCPRC research report on performance-based asphalt pavement specifications.

According to Caltrans, a life-cycle cost analysis completed during the North Red Bluff project shows a savings of $5 million to $10 million over the service life of the project versus conventional pavement rehabilitation. Road user costs, such as traffic delays from maintenance and construction

activities, could add up to another $1 million in savings.

Indeed, as the Long-life Asphalt Pavement strategy has matured, it is now starting to get widespread recognition, including an impressive accumulation of national awards, influencing other pavement designs, and a genuine feeling of pride for those who helped guide the strategy from the “pilot” stage through extensive evaluations to its present place as an established part of the Caltrans pavement design toolbox. Elements of the Long-life Asphalt Pavement Strategy are also making their way into other performance-based pavement specifications, part

of a slow but steady progression in performance-based specifications. And earlier this year, another milestone was reached: the Longlife Asphalt Pavement concept was incorporated for the first time into the authoritative Caltrans Highway Design Manual, now in its seventh edition.

This much is clear: Long-life Asphalt Pavements have arrived, and they are now going mainstream.

The slow but steady progress of the Long-life Asphalt Pavement design strategy in California was chronicled in depth in a 2013 cover story in California Asphalt magazine, when the concept was still being developed and painstaking evaluations and research reports were being conducted. Up until then, there had been some projects that qualified for recognition under the Asphalt Pavement Alliance’s “Perpetual Pavement” criteria, including on the 880 Freeway in Alameda County in the San Francisco Bay Area, a stretch of the 405 Freeway in Los Angeles-Orange

County, and the Central Expressway (Santa Clara County Route G6). Still, Long-life Asphalt Pavements in California were still viewed internally by Caltrans as new and unproven, and projects were not being designed from the ground up as Long-life Asphalt Pavements even though they had many long-life elements, such as thicker layers and a rich bottom.

The big test for the concept was on the 710 Freeway, the truck-heavy route that connects the sprawling Los Angeles-Long Beach Port Complex – one of the busiest ports in the world – to the rest of Southern California and the West Coast. The crumbling concrete pavement was due for replacement, and Caltrans determined it was time for a real-world test of the Long-life Asphalt Pavement design. Construction was done in phases starting in 2001. By 2009 the work attracted the notice of the Los Angeles Times, which featured the project on Page 1. The newspaper praised how the former “concrete

washboard” of the 710 was converted to a smooth asphalt surface that made “your tires purr.”

Caltrans and the University of California Pavement Research Center (UCPRC) conducted extensive after-action evaluations of the 710 that proved the design was performing as expected. John Harvey, Ph.D, P.E., director of the UCPRC, said additional core samples are being obtained this year for another evaluation report that is expected to be published sometime in 2023. So far, he said, the pavement on the 710, approaching two decades on the ground, appears to be holding up well.

“Now that it is in the Caltrans Highway Design Manual, what we are trying to do is get the word out,” Harvey said in an interview with California Asphalt magazine. “Caltrans has the tools now in the CalME software.” CalME is a software program developed by Caltrans and the UCPRC using mechanistic-empirical

methodologies for analyzing and designing the performance of flexible pavements. Notably, the software uses an “incremental recursive” approach that models the entire damage process, not just the initial condition after construction and the final failure condition, according to the UCPRC. CalME simulates the pavement performance starting from the initial undamaged pavement stress, strain and deformation responses to temperature and load to the end failure state, and is calibrated using data from the Caltrans pavement management system.

The 710 experience, and the development of the CalME software, was foundational to the many Long-life Asphalt Pavement projects that have followed, including two on Interstate 5 in the North State, one on I-80 between Sacramento and the San Francisco Bay Area, and another massive project on Interstate 5 heading into downtown Sacramento. The latter project, also recipient of a national award by the Asphalt Pavement Alliance, was sweet validation for Caltrans District 3 Director Amarjeet Benipal, who was a Long-life Asphalt Pavement champion when he was heading up the Division of Pavements, a job that also carries with it the designation as “State Pavement Engineer.”

When Benipal spoke at a CalAPA Asphalt Pavement Conference in Sacramento in 2021, he talked at length, and with obvious pride, of the evolution of the pavement strategy.

“At the beginning of the century, we had a long-life project on LA-710. So I come along, almost a decade later, into the assignment (as state pavement engineer) and there was no additional project after the 710. We talked about it, but nothing was in the works,” Benipal explained.

“So, working with you, and many of your predecessors, we said, ‘OK, we have to do something. We need

Tavares was promoted to director of the department earlier this year.

to put asphalt pavement on the same plane as concrete so we can declare that we actually have a long-life solution with any of the pavement materials. As a result of that, in 2011, we had two projects on Interstate 5 in District 2, one in Red Bluff and one in Weed. And that was because of our collective efforts. Then I said, let’s take that challenge to the next level. Then we took it to District 4 and we did it on Interstate 80 near Dixon. And if you travel through that stretch, or you travel through the other projects I mentioned in District 2, they are performing wonderfully, and that’s really the part that all of you should be proud of.”

But Benipal felt something was missing, a showpiece, and that ultimately led to the Interstate 5 project near downtown Sacramento. By that time he had moved on to become director of District 3, a regional Caltrans district that includes Sacramento.

“We started thinking about, how can we eventually build a long-life project near the state Capitol?”

Benipal recalled. “Not only should we be proud of doing that work, but we can also showcase it to anyone coming to the state, from other states, and coming to the state Capitol.”

And what a showcase. The APA recognition, which will be formally presented to Caltrans and the contractors at a meeting of the California Transportation Commission early next year, was another example of agency-industry collaboration that resulted in an innovative project that has earned praise far and wide.

“You have to keep pushing the ball forward,” Benipal said. “It’s one of those things you have to continue to keep reminding people.”

That project, part of the $370 million Interstate 5 Corridor Enhancement Project, ultimately rehabilitated 67 lane-miles of pavement, ramps and connectors, utilizing some 600,000 tons of asphalt, including a substantial amount of Reclaimed Asphalt Pavement *(RAP). The project was

in 1958, and located in Yuba City, Lamon Construction Co. is a general engineering contractor specializing in earthwork, water, sewer, storm drain, concrete and asphalt paving projects. The company is owned and operated by partners, Steve Ithurburn (President), Henry Lamon (Director) and Ken Norton (Vice President). The majority of Lamon Construction Co.’s projects are in the public works sector and located in Northern California.

Lamon Construction Co. recently took delivery of three new machines from Herrmann Equipment, Inc. to include a Bomag CR1030T 10-foot paving machine, a Bomag CR362 8-foot paver and a Bomag BW190AD-5 roller. “The purchase of these three new Bomag machines came down to service. We have been let down by other suppliers in the past, but it became clear to us, well before the actual purchase, that service and parts availability at Herrmann Equipment was not going to be an issue. Throughout our relationship, Matt Herrmann has always been available when we needed him, and he has consistently maintained the impeccable service that we have come to trust, says Norton. “We purchased both Bomag paving machines and the Bomag roller as a package earlier this year. We have been running all three machines regularly on various projects and everyone is extremely pleased with the performance and the finished product they produce.”

Dean Conard is a Superintendent at Lamon Construction Co. and was involved with the purchase and demo of the Bomag CR1030T paver. “Prior to the purchase the Bomag CR1030T, I was out on a demo the entire day with Matt Herrmann. The machine performed so well I knew it would be an asset to our fleet. Both of our new pavers provide an exceptional, first-rate mat and we are proud to have them on the jobsite.”

Ken Norton trusts in Herrmann Equipment for service after the sale. “Herrmann Equipment is a superior distributor of quality products and we have appreciated their attentiveness before, during and after the sale,” concludes Norton. “We look forward to an on-going relationship with them and future purchases.”

The project was summarized in a 2020 case study produced by the National Asphalt Pavement Association titled, “Perpetual Pavement: Benefits of Partnering to Design Long-Life Pavements.” As the case study noted, “The use of Perpetual Pavement Design in California is part of Caltrans’ careful process of implementing research-based innovation and a desire to implement data-driven processes.” The paper goes on to say, “Lessons learned working with the asphalt pavement industry and the UCPRC are applied to future projects, resulting in higher quality asphalt pavements being designed and constructed for California motorists.” The paper quotes current Caltrans State Pavement Engineer Tom Pyle as saying, “Long-life Pavements are important to Caltrans because they not only make sense environmentally but also economically. Rehabilitation strategies that last for decades eliminate future construction lane closures to the public. This reduces GHG (greenhouse gas) emissions due to no traffic slowdowns in a construction zone, as well as better use of existing resources. While these strategies may cost more now, economically they allow for more roadway repair funding flexibility in the future as demand for the same dollars is lessened.”

The project was also recognized by the Asphalt Pavement Alliance in 2021 with a “Perpetual Pavement By Design” Award. The category, as its name suggests, recognizes newly designed and constructed asphalt roads built over new or reconditioned subgrade that meet strict Perpetual Pavement criteria. The award winners were evaluated by the National Center for Asphalt Technology at Auburn University. “One key indicator of quality in

construction is a smooth, long-life pavement,” said Amy Miller, P.E. National Director of the Asphalt Pavement Alliance in announcing the awards. “Long-life asphalt pavements serve the community, reduce the money needed for maintenance, and conserve raw materials.”

As James Signore, then with the UCPRC, explained in the 2013 magazine article on the design strategy, the long-life designs were developed using mechanisticempirical methods that were deemed the next evolution of pavement design. The mechanisticempirical designs place a greater emphasis on predicting pavement performance.

Mechanistic-empirical methods require characterization of Hot Mix Asphalt mixes to zero in on ruttingresistance, the potential for fatigue cracking and durability. As Signore noted at the time, “Long-life Asphalt Pavements designed with mechanistic-empirical methods require characterization of HMA mixes in terms of their shear (for asphalt layers rutting), stiffness (for fatigue cracking and unbound base and sub-grade rutting), and fatigue performance (for fatigue cracking).”

Ragubar Shrestha is the current Caltrans point-person on the use of the CalME software making the most of the mechanistic-empirical design principles. He said the department has been utilizing the software to make pavement design decisions since the 2015-16 fiscal year.

“All the Caltrans projects for new and rehabilitated overlays are based on mechanistic-empirical design,” he said in an interview. “They are not necessarily three layers. It could be a one-layer system or a two-layer system. But they all are long-life pavements.”

Previously, he said, there was only one value for HMA in the CalME design library, but now there are several, covering many different

conditions, materials and traffic loading conditions. Now designers can draw from many different options to optimize the design for a particular location. “It’s very comprehensive,” he said.

Rita Leahy, Ph.D, P.E., a former technical director of CalAPA, attended countless meetings at Caltrans to help refine the Long-life Asphalt Pavement strategy and help the department and the asphalt pavement industry get through some initial growing pains. She was particularly pleased about the news that the strategy is now included in the authoritative Caltrans Highway Design Manual.

“That is a testament to how effective CalAPA, the Asphalt Institute, UC Davis and the consulting community have been in working with Caltrans on this,” she said in a recent interview with

California Asphalt magazine. “This is great news.”

Dave Newcomb, Ph.D., P.E., is another one who had high praise for the evolution of the California effort. Now a retired consultant, he was formerly vice president for Research & Technology for the National Asphalt Pavement Association, and later a professor of engineering with Texas A&M and researcher for the Texas A&M Transportation Institute. He coauthored an authoritative 2020 report published by the NAPA titled, “Perpetual Pavements: A Manual of Practice.” He referred to the California project by the term, “perpetual pavements,” that is favored by NAPA.

“The other thing with perpetual pavements is speed of construction,” he recalled in a recent interview. “On the 710 project, Caltrans and the contractor did a fantastic job. When you tell people the projected time for the project is two years, and then you get it done in eight weekends, that is super quick. That is the thing the drivers need to see.”

Newcomb also said there is a strong correlation with the Long-life Asphalt Pavement work in California and the current “Balanced Mix Design” initiative to develop mixes that, as the name implies, find the sweet spot to resist cracking and pavement rutting.

“Nowadays people are trying to go toward a Balanced Mixed Design, which fits in perfectly (with the California Long-life Asphalt Pavement design strategy),” he said. “Most of the applications are aiming at the top of the pavement, making it less susceptible to cracking, and less susceptible to rutting, and I think that will play well with the (Long-life) thickness design.”

According to a 2017 technical report produced for Caltrans by the UCPRC, “MechanisticEmpirical (ME) Design: Mix Design Guidance for Use with Asphalt Concrete Performance-Related Specifications,” the following conclusions on performance-based

mix designs further illustrate Newcomb’s point:

“Development of PerformanceRelated Specifications for Mix Design Performance-related specifications for mix design are expected to include tests that directly relate to mix performance, such as the tests for resistance to permanent deformation (related to pavement rutting) and fatigue damage (related to pavement fatigue cracking) that were used in this study. This study shows that it is also important to include mix stiffness as part of the specifications. As shown in Chapter 8, both the fatigue cracking and rutting performance of a pavement are affected by the stiffness of the mix used as the surface layer. In particular, stiffer mix can be beneficial for improving both fatigue cracking and rutting performance. It was also found that the effect of mix design adjustments on individual laboratory tests may be inconsistent with their effect on pavement performance if stiffness is not considered. Although better laboratory performance in general indicates better pavement performance, the opposite may also result when mix stiffness is significantly reduced. As a first step, performance-related specifications should use laboratory test results alone to make them practical. Eventually, however, they should be based on mechanistic-empirical analyses of pavement performance, which themselves use inputs developed from the laboratory test results.”

UCPRC’s Harvey, one of the co-authors of the report, says that in addition to the updated evaluation of the 710 Long-life Asphalt Pavement project, another evaluation is also in the works for the I-5 Red Bluff, that is nearing a decade of service.

“We’re going out and monitoring these projects,” he said. “We’ve been through the learning curve.

We are now looking to apply this elsewhere to the state, and get the benefits.”

In another example of Long-Life Asphalt Pavements coming full circle is the current Caltrans Director, Tony Tavares. In 2013, when he was head of Maintenance for the department, he accepted a “Pavement Pioneer Award” at the CalAPA Fall Conference in Sacramento presented by the Asphalt Pavement Alliance acknowledging the Caltrans innovative work in this area. He later was regional director of Caltrans District 4, where the I-80 Long-Life Asphalt Pavement Project was constructed. Earlier this year he was head of the District 7 regional office in Los Angeles when he spoke at an April 5 CalAPA conference in Brea and included Long-Life Asphalt Pavements as part of the Caltrans emphasis on innovation. He said the department will be “continuing with innovations and efficiencies – looking for those opportunities. And that’s a lot of partnerships with industry. You bring that practical aspect, how to deliver a project, how to deliver asphalt, how to change the specifications, and using our folks and academia, all working together, to find those innovative methods and also being efficient in how we deliver those projects.” A month later he was appointed by the governor to the top post at Caltrans. Perhaps it’s only fitting that he’ll be one of those to be recognized again by the APA for this new crop of innovative projects. When it comes to asphalt pavements, it seems, what goes around, comes around. CA

DURAN & VENABLES, INC.

Built and sustained on the principles of integrity, quality, safety and service since 1979

Duran & Venables was established in 1979 by Charlie Duran and Sean Venables, who had previously worked together for a Bay Area grading and paving contractor. Duran was a field foreman, and Venables worked as an estimator. Together, they decided to start Duran & Venables with the idea of always being honest and fair while providing the best quality services and finished products to a loyal return customer base. Danny Duran is Charlie Duran's brother and has worked for Duran & Venables from the beginning. “I remember we started in 1979 with a Massey Ferguson 30 tractor and an old roller. We were taking on anything and everything from asphalt patching, private residential, and a lot of tennis court paving jobs,” remembers Duran. “We didn't even have a means of

transport, so we would just road our equipment down the street to the next job. The company remained small, adding a few other machines over the next few years. Then, Mark Petersen came on board in 1982 as our estimator, and that is when we started taking on more jobs and larger projects and even purchased our first paving machine.” Mark Petersen continued to serve as lead estimator for Duran & Venables (D&V), working closely with the two owners on all aspects of the business. Then, in 1999, Petersen purchased Duran's shares in the company, making him a 50 percent partner with Venables. Petersen bought out Venables shares in 2017 with a vision of expanding the size and capabilities of the firm. “My father was in the grading business, and I worked for his company for one year after

college. I decided to work outside the family business, so in 1982, I responded to an advertisment for an estimator position at D&V. I got the job and enjoyed working hard and watching the business grow. It was just sort of a natural progression as Charlie started preparing for retirement and I continued to manage the sales and logistics of the daily operations.”

Petersen says that D&V has always been extremely customer oriented. Because of this focus, 80% of its current customer base is made up of repeat customers. Today, the company has 125 team members working in the field and 30 working inside at the Milpitas headquarters. The company's growth has been impressive, going from less than $500,000 near the beginning to more than $55 million in 2021. Ken Bilbo serves as the

operations manager for D&V, and he points to several contributors to the company's success. “The biggest single key to our success has been the investment in our people. We look at everyone here at D&V as an individual family member that is an integral part of an overall larger team effort,” says Bilbo. “Endless hours have been spent training grade checkers, equipment operators, project managers, and those responsible for budgets and productivity. This includes seminars and training in other necessary work skills like communication, negotiating, productivity and leadership.”

Gregg Fisher is vice president for D&V, and he points to the company's project diversity as another factor contributing to the firm's overall success. “We provide a long list of professional services for various project types and scopes,” says Fisher. “It also helps that successful and expanding corporations surround our business in the Bay Area and Silicon Valley like Apple, Adobe, and other large media and technology companies.” Fisher says that most of D&V's work is sold as a grading and paving package. “We work on schools, subdivisions, parks, industrial complexes, public buildings and many other entities. On 90% of these projects, we begin with the earthwork and end with the

paving,” continues Fisher. “The majority of our work is performed from Monterey to Sacramento. Our crews regularly perform everything from 10-ton patch jobs to a 10,000-ton paving project.”

D&V also specializes in paving running tracks for Mondo, one of the first companies to achieve a World Athletics Certified Athletic Track Products certification. “Paving tracks for MONDO is just another way that we keep our company at the forefront of available technology here at D&V. This process originated in Italy and acts as a sort of carpet laid on top of an asphalt track,” says Petersen. “We have put down several of these certified Olympic tracks for MONDO, and what makes it unique is that there is only a 1/8" maximum deviation from 10-foot straight-edge in all directions. Paving at such tight tolerances on a track that is 24 to 30-feet-wide takes knowledge, patience and talent.” D&V paved for MONDO at the Olympic Training Center in Carson, where they put down 4 inches of asphalt in two lifts of half medium hot mix material. “Before we pave the tracks, we first build a model in-house with our engineers who compute and enter the elevations, tolerances and other data. We then put that information into our Trimble Robotic Total Station (RTS) to eliminate the guesswork and achieve these

tight tolerances. We also use this technology when we pave tennis courts,” continues Petersen.

Mike Hinojosa is the paving manager for D&V, and his crews are always ready for any job or challenge. D&V is on various projects right now and just completed a 14,000-ton asphalt paving project on a large subdivision job in Stockton. “Our crews were on three separate subdivision projects recently in Sacramento that included the paving of residential streets and a mainline roadway,” says Hinojosa. “We also recently paved two large parking lots for Topgolf in San Jose. It is always different and challenging from one job to the next, and that certainly keeps it interesting.” D&V currently has two full-time paving crews led by paving superintendent Mike Valdez. The company has a paving fleet comprising five paving machines, including a 4-foot paver, two mid-size LeeBoy machines, a Carlson paver and a large Cat paving machine. In addition, they own several rollers from 3 to 10-ton capacities and other support equipment like skip loaders and skid steers.

D&V became a California Asphalt Pavement Association (CalAPA) member in 2021. Operations manager Ken Bilbo had years of experience as a member in the 1990s when he worked for

another well-known asphalt paving company. “I know from experience just how valuable being a member of CalAPA can be for any size asphalt paving-related company. They provide so many valuable services, including information on current projects and mixes, new technology, environmental compliance, and a long list of educational opportunities,” says Bilbo. “We invest a lot of time in education and training here at D&V, and we rely on CalAPA to provide the veteran educators and experts for seminars, educational materials and other customized training services. So it pays to be a member of the California Asphalt Pavement Association.”

Bilbo concludes by pointing out that the principles of “Integrity, Quality, Safety and Service” that launched D&V continue to sustain the company today. “We continue to follow these principles and strive to be the best grading and paving company in the San Francisco Bay area and beyond. Not the largest, but the best,” says Bilbo. “We remain optimistic about our business and opportunities. But,

we also remain prudent in positioning our company for longterm sustainability.” For more information on Duran & Venables, Inc., please visit their website at www.duran-venables.com or call their Milpitas headquarters at (408) 934-7300. CA

Respected asphalt binder expert Brenda Mooney retires from Valero Energy

laboratory technician. She was promoted to lab supervisor and eventually to manager of product technical services. She was active in several professional associations, including CalAPA, AAPT and the Asphalt Institute. She holds numerous certifications and degrees in chemistry and business management.

"Brenda has been such a tremendous asset for me and the company," said CalAPA Board Secretary Jeff Benedict, one of Mooney's co-workers at Valero. "She answers every question, she returns every cry for help. She never has shied away from tough questions or situations. I am going to miss her 'get it done' attitude. I sincerely wish her the very best in life."

Noted binder expert and "Women of Asphalt" pioneer Brenda Mooney retired from CalAPA member Valero Energy earlier this year, capping an impressive 33-year career that earned her well-deserved praise and admiration from all corners of the industry.

"Brenda has been a steadfast base of knowledge and reason throughout the years,” commented professional colleague Toni Carroll at the time of Mooney’s retirement this summer. "She brought a great attitude to every meeting she attended and always partnered with grace and intelligence. Her departure

from the industry will leave a hole for some time, especially as we gear up the Women of Asphalt California Branch. Brenda has been a great ally and mentor to me personally over the years and I'll truly miss her."

Added longtime industry colleague Adam Hand, Ph.D., who is now Associate Professor at the University of Nevada, Reno, "What more is there it share than Brenda's perpetual smile and positive words!"

Mooney officially retired at the end of June.

Mooney started her career at the Huntway Refinery in Benicia (later acquired by Valero) as a

Another co-worker, Gary Houston, added, "Brenda has created a phenomenal technical system in Valero’s asphalt producing facilities in California and, to her credit, it is very sustainable and will be easy to continue on even as she goes on to her next endeavors, and that is really a credit to her. It is a rock-solid, bullet-proof system that she created, and all the credit goes to her."

A former co-worker, Don Goss, who recently retired from Valero, observed of Mooney: "Brenda Mooney is a 'Super Woman' of asphalt! Her great career at Huntway and Valero is the result of relentless, daily application of her exceptional character and formidable skills to the broad spectrum of challenges which she confronted. Day after day, year after year, she gave generously of herself to her employers, her

workmates, her industry colleagues and friends.

"Throughout her career," Goss added, "Brenda grew in both the theoretical and practical aspects of asphalt technology, becoming highly skilled in asphalt production, product formulation, and quality control, so that today she is considered one of Valero’s 'subject matter experts' in those areas. But she extended her expertise beyond the refinery and terminal gates by participating in numerous technical committee meetings with CalAPA,

the quality of the work that we all do, and has always kept her eyes on the specifications, and participated from a technical perspective and helped a lot of us learn more about the asphalt industry in the way she has contributed."

Mooney was well known and respected in the Asphalt Institute, a national partner of CalAPA that represents the asphalt binder industry.

“After Don Goss retired, I got to know Brenda much better,” said Asphalt Institute Senior Regional

That is where I got to hear about her frequent trips to Europe, and her commitment to leading the local Humane Society. With her smile and positive demeanor, it was a pleasure to interact with her. Brenda, you will be missed!”

In an interview with California Asphalt, Mooney said she will devote more of her time postretirement with her husband, Bill, and one of her passions, animal welfare. She is currently the president of the Humane Society of the North Bay, which is located in

Asphalt industry, Bakersfield community mourns the passing of Majid 'Mo' Mojibi

The asphalt industry and the Bakersfield community was shocked and saddened by the unexpected death of longtime San Joaquin Refining President Majid "Mo" Mojibi, described variously as a "community pillar" and "a great man" known for his philanthropy and dedication to numerous causes in the greater Bakersfield community. He was 75.

Mojibi was struck by a vehicle in downtown Bakersfield Sept. 17 as he was walking from his parked car near the intersection of F and 19th streets. He was rushed to a local hospital, Kern Medical, but succumbed to his injuries the following day. The Bakersfield Police Department is investigating the death and has interviewed the motorist who struck Mojibi, according to Bakersfield Police Sgt. Robert Pair. No charges against the motorist had been filed, Pair said, but the investigation remained open as of early October.

Mojibi was known far and wide as the longtime president of San Joaquin Refining, a major local employer in Kern County. As a supplier of liquid asphalt to the region, San Joaquin Refining Co. is a longtime member of the California Asphalt Pavement Association. One company employee echoed the sentiments of many when he said the news came as a shock to everyone who knew Mojibi and was "very sad."

As the news about his passing spread around the greater Bakersfield area, tributes and condolences poured in.

"Bakersfield lost a great man last weekend and he will be missed by many," wrote Michael Hunt in the local newspaper, the Bakersfield Californian. "Majid (Mo) Mojibi was a well-respected family man, businessman and philanthropist. He and his family have made enormous

contributions to our local community of the past 40-plus years and his legacy will remain for years to come." A local radio station also set aside part of its regular programming to recall Mojibi's legacy, with one guest referring to him as a “community pillar.” A celebration of life was scheduled for Oct. 8 at the Bakersfield Country Club.

Majid “Mo” Mojibi-Yazdi was born in Iran on Feb. 2, 1947, but emigrated to England to study catering and restaurant management. When a friend got a job in the United States as a petroleum engineer in Taft, in California’s Central Valley, Mojibi followed him to California with a total of $18 in his pocket, family members recounted.

His wife, Willa Mojibi, told the local newspaper that “He’d always wanted to come to the states,” and she said he was very proud when he became a naturalized U.S. citizen in 1980.

While in California, he worked various jobs until a family he was renting a room from helped him get a job with an oil company. While working there, he studied business at Bakersfield College, where he met his future wife, and later at California State University, Bakersfield, where he earned a business degree.

In the late 1970s, his bosses made him an offer: turn around a refinery they just purchased in northwest Bakersfield. If he could show a profit within three months, it was said, he could earn a share of ownership in the refinery. His success in that endeavor and many others, including pistachio farming and commercial development in Kern County, became stuff of local legend.

Well into his 70s he remained prominent face in the industry and in the Bakersfield community

through his community boosterism, development projects and many charitable works, many of which were made with little fanfare. He was known to help individuals in need, his family said, focusing on people with potential who just needed a little help to succeed.

“I think it goes back to the early breaks he got,” his son, Cyrus, told the local newspaper.

Mojibi and his wife often hosted fundraisers at his home to support local charities. In just one recent example of the family's philanthropy, Majid and his wife hosted a fundraising event at their home last October to benefit the League of Dreams of Kern County, an adaptive sports league that helps athletes aged 5 to 22 that have physical, developmental and cognitive disabilities.

Mojibi is survived by three siblings, sister, Haleigh Burlingham, sister Nanice Mojibi and brother Hamid Mojibi. He is also survived by three children – Darius (wife Cathy), Cyrus (wife Amanda) and Marcella Tattanach (husband David) – and seven grandchildren: Emma, Ari, Ian, Beck, Pia, Riley and Carmen. CA
