Paver, roller help asphalt company in tight urban location
Brand-new, high-tech paving equipment is helping South Carolina’s King Asphalt pave in tight urban quarters.
In October, using an HD+ 120 VV HF high frequency roller from Hamm Compaction Division, and a Vision 5200-2 10-foot tracked paver from Vögele America, King Asphalt placed 600 tons of hot mix asphalt on Ashmore Bridge Road, Greenville, South Carolina, in a congested city location.
Elsewhere in Greenville, King’s W 1900 Combo from Wirtgen was cold milling urban streets for the South Carolina DOT, a project funded by the American Recovery and Reinvestment Act.
“We’re leveling on one end of the road, then paving the entire main line down 1,800 feet,” says Danny Michael, paving operations supervisor, King Asphalt, Liberty, South Carolina. “We’re placing 2 inches of Type B surface mix, a coarser main line mix, compacted to 1 3?4 inches.” The width ranged from 40 feet wide at intersections, to 24 feet wide in the main line.
The organization of the paver’s components makes day-to-day operation easy, Michael says. “After we set it up a couple of times, and saw what goes where, we found it to be pretty simple,” he says. “Its tractor is really powerful. We’ve already extended it out to a full 19 feet, and even then it has no problem pushing a truck.”
King Asphalt’s new Vision 5200-2 has Vögele’s exclusive Niveltronic system, complete with averaging beam. “We haven’t put it to its fullest use yet, but we use it every day,” says King general manager Mike Crenshaw. “We really like the way the Niveltronic system is intertwined into the rest of the paver. All the leveling controls tie in to the control panel, with no extra boxes.” The averaging beam is 40 feet long, and two extensions will bring it to 50 feet.
The fact that the Vision generator is under the hood makes a big difference for King. “That helps visibility and makes changing the screed much easier,” Crenshaw says. “The generator for the screed heat is not on the screed itself.”
The Hamm roller also was new in 2009. “The HD+ 120 gives us a lot better compaction than we used to get,” Michael says. “The vibratory system sets speed and vibration together automatically. The operator will set the vibration, and no matter what speed he’s running, the vibration will stay the same. It’s set automatically, but it’s variable. As he takes off, the vibration automatically starts. As he slows down, it stops itself.”
And the high-vibration of the VV HF model is giving King Asphalt the edge it needs to win bonuses. “We have been able to get full pay a lot more consistently with the roller, and get some bonuses as well,” Crenshaw said. “We have to get a 92, but with the HD+ we consistently get 93s and 94s.” EW

Recycler efficiently reuses hot mix asphalt layer
Roadtec’s cold-in-place recycling train, a cost-effective alternative to conventional methods of rebuilding asphalt roadways that reuses 100 percent of the old HMA layer, employs the Roadtec’s RT-500 cold recycler to crush and screen RAP produced by the RX-900 cold planer, and an on-board pugmill mixes emulsion into the recycled material. A windrow loader can pick up the material and feed it to a conventional paver; however, an optional conveyor can load directly into the paver from the RT-500.
Roller simplifies frequency and amplitude adjustment
Improve performance with Hamm’s HD+ Series of asphalt rollers, available in the 13.8-ton HD+ 120 or the 14.5-ton HD+ 140 models. Choose from three models in each size – conventional vibration in both drums, vibration in the front and oscillation compaction in the rear or high frequency vibration to 4,020 vpm. Frequency and amplitude can be controlled independently on either drum for increased flexibility in the roll train, and can be adjusted by the operator on the dashboard.
