Innovation continues. We are excited about delivering more stories on creative solutions via projects, contests winners, new ICPI resources, education opportunities, developments in national standards, and research on segmental concrete pavements. Obviously, the great advantage of electronic articles is another form of interlock, i.e., the ability to link to other documents and videos that support them by increasing editorial depth. Advertisements can issue calls-to-action by clicking a link that connects seller and potential buyer immediately, as well as sending almost immediate feedback on advertising inquiries. This issue features revamped street in downtown Davis, California, that artfully combines interlocking (ICP) and permeable interlocking concrete pavements (PICP) in a technically correct manner.

surface cleaning. Of interest to contractors is a brief article on ICPI’s emerging learning management system or LMS called The Hardscape Institute. ICPI is making several specialist courses available online as learning modules for 24/7 access, a great convenience for those who want to learn more about residential and commercial construction. The course also qualifies for continuing education credits for ICPI’s 2500 certified concrete paver installers. Our only hesitation in this digital sphere is that electronic formats can carry a higher risk of being more easily ignored than printed formats. The Internet is a great, sort of a ginormous file drawer with fabulous search engines. But its breadth of information is mostly greater than depth. Print still rules (or digital print) when it comes to conveying depth and complex information. From a human perspective, eyes viewing a screen, tablet or phone can react more quickly than hands holding a magazine in making a decision (or not) to browse pages and read articles. We hope that the quality and relevance of the content renders this doubt baseless.Â

Interlocking & Permeable Interlocking Concrete Pavements Address Functional and Visual Concerns
I Reminiscent of The Netherlands, bicycles are a major means of transportation around the City of Davis and onto the UC Davis campus via Third Street.
nterlocking concrete pavement improved the redesign of Third Street in Davis, California (pop. 70,000) by clearer visual and functional connections with the century-old UC Davis campus’ main entrance. Directly adjacent to the university campus, downtown Davis projects a classic “college town” feel; compact, vibrant and bicycle-friendly. The place is so simpatico with bicyclists that it was voted the top California city for cycling. Given this reputation, it’s no surprise that Davis supports the U.S. Bicycle Hall of Fame and the California Bicycle Museum. Third Street is best known locally as the site for the year-round farmer’s market. Long envisioned as a gateway between UC Davis and downtown, plans to create a signature bicycle and pedestrian corridor have been planned for decades with public and incremental private improvements occurring throughout the years. “The Third Street segment has always been on our list as an important bridge between the university and our downtown area,” says Brian Abbanat, Senior Transportation Planner for the City of Davis. Prior to the redesign, the two-block area of Third Street leading to the campus entrance served as a pass-through for vehicles, pedestrians and bicyclists. There wasn’t much character and sense of place, he explains. The combination of frayed concrete sidewalks and roadways plus flooding along the flat street due to poor drainage and tree roots blocking gutters and drains led to the city’s decision to reconstruct the area. The flatness of Davis’ terrain is a blessing and curse: a blessing to cyclists and a curse on stormwater drainage. Plans called for a comprehensive streetscape improvement addressing drainage Continues on page 7

problems while creating a gateway street between the city’s downtown and the university entrance, points out Nathan Lozier, vice president of RHAA Landscape Architecture and Planning in San Francisco. “Davis is a bicycle town. Over 4,000 bicycles travel through the Third Street area between downtown and UC Davis daily. Diversion bollards to control automobile traffic and deep crossstreet drainage swales were safety hazards to bicyclists,” he says. There is also much pedestrian traffic, so it was important to address narrow sidewalks, deteriorating pavement

and inadequate lighting for pedestrians and bicyclists, he adds. Visually, the plan also recommended better connecting downtown to the campus, says Mr. Lozier. “Prior to improvements, you could stand at the downtown end of the two-block area and not even know that the university was there,” he says. “The existing street profile was also steeply crowned to divert water into deep gutters along the roadway.” The 850 foot (245 m) street length includes 675 ft (206 m) of permeable interlocking concrete pavement (PICP). The two-
block area previously had four-foot wide sidewalks next to four-foot wide tree lawns with on-street parking and bollards divert passthrough traffic at an intersection. The new design eliminates onstreet parking in exchange for wider sidewalks, flattens the street to make it safer for pedestrians and bicycles, installs more bicycle racks throughout the area, and uses custom art—an obelisk of bicycle parts—in the center of a newly rebuilt intersection circle to control traffic flow.
In addition to the streetscape improvements, the project includes rebuilding three intersections, two of which with interlocking pavers and replacement of concrete entryways and patio areas with pavers for adjacent business owners. “Several business owners welcomed the expansion of pavers onto their properties, which expanded the sense-of-place and seamlessly tied their businesses to the new streetscape,” explains John Martin, senior associate, RHAA Landscape Architecture and Planning. A combination of PICP and (nonpermeable) interlocking concrete pavement was selected for the

project, with non-permeable pavers used in intersections and entryways into service alleys, says Martin. The concrete pavers were supplied and installed by ICPI members. “City representatives requested pavers over asphalt anywhere that vehicles turned to reduce any risk of pavers shifting,” he explains. PICP was chosen for the roadway to reduce runoff and flooding while improving quality of the stormwater. “In the roadway, the permeable and non-permeable pavers are 80 mm thick,” says Mr. Martin. Three colors of pavers are used in the herringbone and circular patterns in the project. “The design originally specified a 7/8 inch (22 mm) bed of ASTM No. 8 stone, over

4 inches (100 mm) of ASTM No. 57 on 6 inches (150 mm) of ASTM No. 2. We reviewed more readily available local aggregates and substituted them when we had difficulty finding the originally specified aggregates,” he adds. “Our stakeholders recognized that permeable pavers are best practice for this use and the subgrade was fairly permeable because it was a former creek bed with gravelly, sandy soils,” says Mr. Lozier. “Pavers were also attractive because the project included some reconstruction of underground utilities, and city representatives liked the idea that future maintenance could be easier because pavers can be removed and

replaced more easily for repair of utilities than concrete or asphalt.” Residents expressed concern about the pavers in public meetings held to allow residents to comment on proposed designs, says Lozier. “They were worried that pavers would not provide a smooth surface that was comfortable and safe for pedestrians and bicyclists,” he explains. “We were able to point out other areas in the city where pavers are used, and everyone agreed that there were no problems.” The original design proposed a fairly intricate paving pattern. “We talked to contractors during the development of the plan to ensure that the design was achievable during installation,” says Mr. Lozier. “The layout uses a herringbone

pattern with selected pavers laid out with different colors to suggest a circular design.” In addition to changing specifications for aggregate used in the project to address difficulty obtaining material, there was also a need to develop an engineering detail at the intersection corner, says Mr. Martin. “Some of the intersection corners are flush with the sidewalks to allow delivery trucks to drive onto them, so the paving profile had to be adjusted to transition from a pedestrian-only profile to a vehicular traffic profile at these corners,” he explains. This required additional 6 inches of ASTM No. 2 stone to the base and a reduction of the ASTM No. 57 stone, he adds.
“We have never used interlocking pavers on a city street before this project, only on private parking lots, but we were comfortable with the subgrade engineering,” says Mr. Abbanat. “The area is not heavily traveled but there are some heavy trucks delivering to local businesses, so the pavement needed to handle that weight.” Feedback on the project has been positive, and interlocking pavers could be considered for future projects if appropriate, says Mr. Abbanat. “Pavers are an important factor when creating a pedestrian-friendly feel for an area that also includes vehicle and bicycle traffic.”

Recent Developments in PICP Cleaning Present Owner Solutions & Contractor Business Opportunities
Equipment Innovations Support Cost- and Time-Effective Restorative Maintenance
A business opportunity is waiting: millions of square meters of PICP are in need of cleaning.

ermeable interlocking concrete pavement (PICP) reduces stormwater runoff volumes and rates, while filtering pollutants. PICP has an admirable track record in paying for itself by reducing or eliminating detention ponds. In older cities with combined sanitary and storm sewer system, PICP presents a costeffective means to reducing flows
InterlockDesign.org
to wastewater treatment plants and related processing costs. However, when civil engineers, landscape architects, architects and contractors recommend PICP, owners may resist as a result of their own or someone else’s experience with PICP clogging. In other cases, the owner won’t receive education on what’s required to clean PICP, or if received, doesn’t want to spend money for surface cleaning.
These situations lead to lack of maintenance and clogging. The notion of clogging means that water puddles on a PICP surface rather than infiltrating quickly. There may be some infiltration into the surface and base, but it is very slow. In many cases, water puddles in places on the surface, and then moves to another area that more rapidly infiltrates the stormwater.
The puddles on this PICP indicate the start of surface clogging due to sediment in runoff received from adjacent impervious pavements. Why not clean them as well?
The biggest factor effecting clogging is the area of contributing impervious pavement delivering sediment to the PICP. There are many projects with no contributing drainage area or CDA. They usually need little if any cleaning. In contrast, sediment from vehicles and especially deteriorating asphalt surfaces deliver small particles that enter the PICP joints and slow infiltration. Owners don’t think of the PICP as a system, instead, they view it as “just another pavement” that requires little maintenance, says Matt Otero, chief operating officer at Designs by Stonescapes in Commerce City, Colorado. “There is a lack of education about how PICP works and why routine maintenance is important.” PICP is a drainage system that must be maintained the same way any other type of filtration system would, he says. “There should also be some thought put in to the design of surrounding landscape areas to minimize runoff debris.”
Inexpensive routine PICP maintenance includes brooms, leaf blowers, rotary brushes, and shop vacs. More expensive methods for larger areas involve using regenerative air machines that, like these other methods, remove loose dirt, leaves and other debris from pavers and from the top of joints before it enters them via rain and tire traffic. This keeps the pavement infiltrating as designed with minimal replacement of joint aggregate. Unfortunately, most PICP and public agencies owners don’t follow a
routine maintenance schedule. So when clogging occurs, more intensive, restorative maintenance is required that involves removal and replacement of sediment and joint stone. This is a more costly, timeconsuming process. The Interlocking Concrete Pavement Institute (ICPI) members, staff and other organizations have researched and witness demonstrations on the effectiveness of vacuum machines withdrawing sediment and aggregate from 3-inch deep (~80 mm), ~3/16inch (5 mm) or larger width joints typical to many PICP projects. The majority of machines are effective, but a bit inefficient because they require several passes to remove these materials. Moreover, the sediment often binds the aggregate, making both difficult to withdraw. Fortunately, recent research and cleaning demonstrations have uncovered three innovative approaches to restoring infiltration of clogged PICP surfaces. These require Continues on page 15

handle larger, more complex jobs, he experimented with a variety of vacuums and vacuum trucks, but settled on a less expensive, more portable machine that can remove aggregate and debris from PICP joints in one pass. “I modified a Ditch Witch FX-20 that can be towed behind a pickup truck and be taken into areas that don’t accommodate larger
equipment,” says Mr. Otero. College campuses that use PICP in common areas, walkways and patio areas, and At a demonstration in St. Louis, the TYPHOON on the right blows out sediment and soiled aggregate from the joints.

small parking lots are two examples of areas that require access using a smaller vehicle. “The vacuum heads and hoses also work well in corners and up against walls where sediment accumulates.” Mr. Otero experimented with different sized vacuum heads that rendered different cleaning levels. “A 24-inch (600 mm) diameter vacuum head that pulls half of the joint material out works well for pavements that are less dirty. But a pavement that has gone five years with no cleaning requires a 6-inch (150 mm) head that pulls most of the joint material out,” he says. The equipment can easily be operated by a two-man crew with minimum training. In fact, he cross trains his employees to handle the restorative maintenance as well as installation to give him flexibility when scheduling work. Moving from Colorado to Minnesota, the six-year effort to develop TYPHOON, a compressed air system to clean PICP and remove joint material began with Steve Jones, inventor and president of Pave Tech located near Minneapolis. He discovered effectiveness and simplicity of using compressed air

without water to clean joints. “The compressed air blows the joint material out just as a water pressure based system, but there is no sloppy mess when using air and no loss of surface as one would get from water pressure washing.” The TYPHOON has a rotating wand with nozzles that is attached to a large 115 HP air compressor that focuses controlled, high pressure air in the joints to remove clogging sediment, debris and aggregate. It is followed by the PAVEVAC, which is attached to a high volume high suction (27 in. or 675 mm of Hg), vac truck or trailer, to complete cleaning the joints and surface by removing loosened debris and aggregate from the PICP surface. “A three-man crew can remove silt, debris and joint material on 1,000 square feet (100 m2) in about an hour,” says Mr. Jones. “It takes us a less than an hour to train someone to properly use the equipment.” Training includes how to work with air compressed at
200 psi (1.4 MPa), a truck-mounted vacuum exerting 27 inches (68 mm) of Hg suction, plus safe operation of hoses. Moving to Calgary, Alberta, the home of Badger Daylighting that offers its well-known excavation trucks across Canada and U.S. Known as Badgers or Badger Hydrovacs, they use high-pressure water and vacuum systems mounted on a truck to remove soil and expose buried infrastructure or prepare an area for future work. This daylighting method for utility lines practically eliminates risk of damaging pipes and wires, and risk of worker injury associated with hydraulic excavation equipment. The newest innovation for the company is a modification of the vacuum hose that can be used to clean PICP. “Specialized nozzles and cleaning techniques keep the water spray focused on the pavement to act as a high-powered carpet cleaner Continues on page 17

that removes stains, graffiti and clogged joint material,” says Tim Reiber, vice president of sales and marketing for the company. “The pressure can be set to whatever level is needed and the truck’s large tank can hold 1,500 to 1,800 gallons of water and 11 (cubic) yards of debris, which means a large area of pavement—200 to 300 linear feet—can be cleaned and joint material removed in an eight-hour day.” PICP contractors who would like to offer PICP cleaning and maintenance services should evaluate equipment options carefully. They should keep in mind the size of projects they’d like to address and match equipment to them. Stormwater regulations are placing increased emphasis on inspection and maintenance. This provides a business opportunity for maintenance contracts. Developing such opportunities will involve pricing labor and equipment costs for cleaning a range of PICP areas with adjacent
uses, landscaping and pavements contributing runoff and debris. Mr. Otero focused on equipment to handle restorative maintenance informed by the type of permeable pavements he expected to maintain. Spending the time and money to build exactly what he needed was worthwhile, he says. “Not only does the maintenance service ensure ongoing performance of the permeable pavement, but general contractors like the fact that they don’t have to protect the pavement as they finish construction of an area, “he says. “The ability to offer maintenance services to my installation customers, general contractors and other PICP owners is a business decision to grow my business.”
