Select, Haul Paving Equipment
IIn this month’s edition of AsphaltPro, we’re including the annual training directory supplement. This year, we asked hotmix asphalt (HMA) plant manufacturers and component suppliers to share a training tidbit with readers. One OEM who fits more squarely into the product theme this month—that being paving equipment and pavement maintenance equipment—shared information pertaining to loading and hauling equipment properly. Troy Geisler, the vice president of sales and marketing for Talbert Manufacturing, Rensselaer, Indiana, shared the following article.
Paving equipment presents unique challenges when it comes to transportation. In addition to low ground clearance and gentle slope transitions from the front ramps to the deck and from the deck to the rear of the trailer, operators must also consider mixed-load versatility to maximize not only efficiency, but overall trailer return on investment (ROI). Additionally, operators must select the right trailer to ensure the safety of crews, the public and equipment. Here are three considerations to help contractors select an appropriate trailer for safe, efficient paving equipment hauling.
When it comes to hauling paving equipment, one of the biggest challenges is often getting the equipment onto the trailer. Rollers, pavers and other low-clearance equipment require longer loading inclines, whether loading from the front or rear. Larger capacity models also require a gentler load angle at the rear. Meeting this requirement isn’t impossible, though, it just takes the right approach.
For equipment 25 tons or under, tag-a-long trailer models can be used to transport low-clearance equipment. Load angles will vary by manufacturer with some as low as 7-degrees. However, minimizing load angle is achieved through longer ramps and beavertails. This can limit where a trailer can be loaded or offloaded. Additionally, longer ramps are also heavier, making raising and lowering them manually a labor-intensive process. To eliminate the need to handle heavy ramps, look for a trailer with air ramp or air tilt capabilities.
Removable gooseneck trailers are another option. This design eliminates the need to drive up and over the trailer’s rear axle saving time, hassle and expense. These trailers don’t always provide a low load angle, though, so it’s best to work with a manufacturer for a custom design that’s optimized for any intended load, whether that’s paving equipment or a mix of other construction equipment.
Additionally, hybrid models are available that combine the benefits of a lowboy design with specialized features for hauling paving equipment. These units offer a longer loading incline.
Lastly, when considering load angle—regardless of whether equipment approaches the trailer from the front or rear—a smooth transition from surface to surface is imperative. Any bumps between the ground and the deck or the deck and the rear bridge can make loading more difficult and dangerous because it forces equipment operators to increase power to clear the obstacle.
Next to load angle, capacity is probably the most important factor in selecting a trailer for a job. Not all 55-ton lowboys are created equal. They might all be capable of hauling 55-tons, but informed operators know load concentration plays a huge role in how well they perform at that weight.
Some trailers will need the entire deck length to haul 55 tons safely, while a trailer from another manufacturer might only need half the deck length for the same weight. Because loads are rarely uniform, having a trailer rated in half-deck capacity gives operators a more realistic indication of what the trailer will be able to handle without structural failure.
Manufacturers that offer half-deck capacity usually design with a twopoint rigid load base that accounts for the tire spacing—or hot spots—of large equipment and heavy machinery.
In addition to load angle and capacity, operators must also consider the size of the equipment they will be hauling. Starting with the largest piece of equipment, identify the height, width and weight. Keep in mind what’s on the spec sheet might not include accessories. Additionally,
Some trailers feature specially designed “bolt-on” ramps that provide a more gradual load angle at the rear—15-degrees rather than the standard 35-degree angle.
Assess Equipment Dimensions
1. Start with the largest piece of equipment 2. Identify its height, width and weight 3. Identify and add in accessories 4. Do this for all pieces of equipment moving in one trip 5. Factor all elements into the combined weight and dimensions
operations looking to move multiple pieces of equipment in one trip should factor in the combined weight and dimensions.
This information will help determine the maximum loaded deck height to keep the load from being oversized—less than 13 feet, 6 inches tall. All trailers are designed with a certain degree of camber, or the arch that forms in the center of an empty trailer, which helps prevent excessive deflection in the main beams. As the trailer is loaded, the arch flattens. A full load means a flat deck, resulting in the advertised loaded deck height. Keep in mind, a trailer that’s not loaded to capacity might be higher because the deck has not completely flattened under the weight of the load.
Once maximum dimensions are determined, it’s time to find a trailer that brings it all together. Selecting a trailer for paving equipment might come with a few more considerations, but having the right rig promises increased safety and efficiency on every job. Taking the time to work through the options with experienced dealers and manufacturers helps operations ensure they’ve got the right trailer riding between the road and the load for long-term success.

ARA
The outlook for equipment rental revenue, comprised of the construction/industrial and general tool segments, improved during the second quarter of 2021. The updated second quarter forecast released by the American Rental Association (ARA), Moline, Illinois, called for equipment rental revenue to exceed $47.8 billion in 2021, nearly a 3.5% increase over 2020 and greater than first quarter’s forecast that called for a 3.1% increase this year.
Overall, the ARA forecast calls for a 9.68% increase in revenue in 2022 to reach nearly $52.5 billion, surpassing the equipment rental industry’s previous peak revenue of nearly $51 billion in 2019. Growth is expected to be 3.9% in 2023, 2.4% in 2024 and 3.5% in 2025 to total $57.7 billion.
The revenue increases are fueled by the expected strong demand for construction and industrial revenue, particularly in 2022, when the segment’s revenues are expected to jump 11.9 percent to $38.9 billion, surpassing the record $37.7 billion in revenue set in 2019.
Also, with the likely passage of the Infrastructure Investment and Jobs Act of 2021 (IIJA) by the U.S. Congress, the future forecast for equipment rental revenue in 2022 and beyond could be even more robust.
“Once final passage occurs, we will have more specific analysis built into future forecasts, but at first glance it looks like the IIJA could increase rental revenues by about $8 billion over the eightyear spending program the IIJA authorizes,” said John McClelland,

ARA vice president for government affairs and chief economist. “That would roughly amount to an increase in rental revenues for construction and industrial equipment of 7.8% over the current forecast. While we need details on how and when the money will be spent to provide a more complete forecast on the IIJA’s impact on the equipment and event rental industry, early analysis is quite positive.”
Scott Hazelton, director, economics and country risk, IHS Markit, Andover, Massachusetts, said the timing of the infrastructure spending remains unclear, making it difficult to assess the rental forecast implications over time, but that the company, which provides data and analysis for the ARA Rentalytics forecasting service, expects to start incorporating the details into the next quarterly rental revenue forecast update.
For the time being, Hazelton said the outlook in second quarter is more positive than the first quarter because the forecast for nonresidential construction had improved and the American Institute of Architects billings index had moved into positive territory.
“When that index indicates expansion for three consecutive months, there is a high likelihood that nonresidential construction will pick up 12 to 18 months later. While this only moves the nonresidential forecast from roughly flat to modest growth, it is enough to move rental equipment demand up,” Hazelton said.
In addition, he said some of the $350 billion in undesignated funds to state and municipal governments in the American Rescue Plan is expected to be used for construction projects, which also translates into more demand for equipment rental.
Perhaps the most interesting figures included in the new forecast concern the outlook for investment. According to ARA Rentalytics, those in the construction and industrial segment are expected to increase investment this year by 48.1% to $7.2 billion and another 40% in 2022 to reach nearly $10.1 billion, surpassing the peak industry investment in equipment of $9.95 billion in 2019.
“I’m especially interested in our investment forecast. Investment in new equipment dropped precipitously—51 percent—in 2020 and is now expected to rebound by 48% in 2021 and 40% in 2022. This forecast is supported by our analysis of industry metrics that show increases in physical utilization, fleet age and fleet turnover,” McClelland said. “These measures suggest that there has been de-fleeting and aging of the fleet during the pandemic as a reaction to the resulting economic downturn. With the economy now in recovery, demand for rental equipment is increasing. With physical utilization already high, rental companies must make significant investments in new fleet to meet that demand.”
In addition, investment in general tool equipment is expected to increase by 19.5 percent this year to reach $3.31 billion and then grow another 22.1 percent in 2022 to teach $4.04 billion.

DYNAPAC
For more than 50 years, LHC Inc. has provided construction services to Montana’s Flathead Valley. It performs some of the Treasure State’s largest, most complex and high-profile projects, including the construction of a nearly $34 million bypass around its home city of Kalispell. LHC’s services include design, engineering and construction of all types of infrastructure undertakings, as well as site work for commercial and other properties. It self-performs nearly every aspect of a project, including mass earthwork, utility installation, subgrade prep and asphalt paving. LHC supplies the materials for the latter from three strategically located gravel pits around the Flathead Valley. LHC recently added its first two Dynapac CC6200 VI rollers to its asphalt paving operations. With an operating mass of 27,340 pounds and 84-inch drum width, the CC6200 VI is the largest in Dynapac’s tandem rollers lineup.
Operators Dustin Yeadon and Stanley Appelt said the machines have increased productivity and efficiency. “We call them the Swiss Army knives of compaction because they actually work great in all three paving stages: breakdown, intermediate and finish,” Appelt said. “Typically, we just use them for the latter two because you can do both virtually simultaneously with a CC6200 VI.”
Yeadon added, “The ability to get the job done with fewer passes gives us time, labor and fuel savings. We basically can run all day on less than half a tank. And, if we can handle two stages with one machine, that eliminates the need for additional rollers, which increases the savings.”
Dynapac designed its CC asphalt tandem rollers for high vibration frequency with low amplitude to maintain high efficiency on modern, thin asphalt layers. This allows them to compact quickly without crushing the aggregate material. They can also be used for thick layers with high amplitude and a “normal” vibration frequency. A wide frequency and amplitude range provides optimization in any application.
“Being able to adjust the vibration frequency increases versatility,” Appelt said. “We used the CC6200s on everything from smaller parking lots to large-scale highway projects. You can set your numbers to what you need, and it will tell you the range of where you need to be speedwise for optimized production. That helps with efficiency.”
Vibration frequency is set through the new instrument panel and controls that were designed with simplicity in mind. A bigger touch screen ensures maximum visibility. The latest technology simplifies roller operation and ensures optimized handling, thus increasing the quality of the compaction job.
“It’s very user-friendly with a dynamic screen that gives you instant feedback with information such as where you’re at in terms of impacts per foot,” Appelt said. “You can input your numbers pre-workday, so you can get right to work when it’s time. If you do need to make a quick adjustment, it’s two or three buttons and you’re back to rolling.”
Yeadon and Appelt can set how often water from the high-capacity water tank is sprayed on the drums with the control panel and a joystick button. The tank can be filled from both sides of the roller, and there is a two-bar setup on both drums.
LHC Inc. purchased the Dynapac CC6200 VI rollers from Modern Machinery with the assistance of Territory Manager Ben Ralls. Modern has a long history with Dynapac in Montana and Idaho, and earlier this year, it added Wyoming, Washington and Oregon to its territory, making it one of North America’s largest Dynapac dealers.
“Modern is well-respected in the market and a perfect fit for Dynapac,” said Dynapac North America Vice President of Sales Jamie Roush when the expansion was announced. “This partnership will enable us to strengthen our brand presence and customer support even further in this region.”

VÖGELE
The Vögele Super 1800-3i SprayJet paver with VR 600 screed with rear-mounted extensions offers a way to place to place ultrathin bonded overlays without worrying about tack tracking or pickup in front of the paver. Using polymer-modified emulsion from the onboard tank, a computer-controlled spray system built into the Super 1800-3i SprayJet places a bond coat over a width up to 19 feet 8 inches directly in front of the ultrathin bonded overlay.
The Vögele Super 1800-3i SprayJet has five spray bars with a total of 24 high-quality spray nozzles. Spaced 10 inches apart with a 120° spray cone, these are designed to offer a seamless application of emulsion. Depending on the type of emulsion and nozzle size, the rate of spread can be varied between 0.06 to 0.33 pounds per square foot. All the paver operator has to do is set the required quantity before spraying starts. This Vögele SprayJet technology makes it possible to apply bitumen emulsion and perform asphalt paving in one step.
produces a uniform film of emulsion, which covers the entire surface without overlaps. The nozzles operate in pulsed mode rather than continuously. This, combined with the low spraying pressure of 43.5 pounds per square inch, means that misting is almost completely prevented.
On top of this bond coat, the paver immediately places a polymer-modified, open-graded surface mix—fed by truck or material transfer vehicle—that cures very rapidly as it is compacted by a static roller.
