Quality asphalt paving and resiliency equals longevity

Paving Innovations

Barriere began the rehabilitation of Rte. 23 by milling off and recycling 1 1/2 to 1 3/4 inches of the old asphalt with Roadtec cold asphalt planers. The contractor relied on its new RX-900 Roadtec milling machine plus a new, smaller Roadtec RX-700 that it was evaluating for expansion of the division. With the machines working together, they were able to mill one full 12-foot-wide lane length a day.
Barriere used some of its millings as base course material down near the town of Venice in the hurricane-ravaged areas. The remainder was trucked back to the asphalt plant site for recycling.

The Roadtec Shuttle Buggy SB-2500C MTV's function was to assure continuous paving and reduce any stop-start paver impact motions that could possibly reduce available financial incentives.

A Broce MK-1 transfer sweeper with conveyor and a separate dump truck immediately followed two Broce CR-350 brooms that were working in a stepped overlay formation in order to sweep the newly milled surface clean of all remaining millings and other debris. Sweeping assured a clean, dry roadway for the new asphalt to bond with the milled surface.

Led by two powerful Roadtec milling machines and a Roadtec SB-2500 material transfer vehicle, a modern asphalt paving train relentlessly made its way along the inside high-speed travel lane of LA Rte. 23. The train did far more, however, than just rehabilitate a portion of the mainline highway as it went. It brought back almost three decades of significant memories.

In 1981, over twenty-seven years ago, Bertrand A. Wilson was a foreman and James Fulton was a screed operator on a paver. Both men were working for Barriere Construction Co. LLC on a new four-mile long highway project in Plaquemines Parish, about 30 miles south of New Orleans.

Now, over two and a half decades later, Wilson and Fulton are back on the same job. As times change, so did their positions. They are still with Barriere, but now Bert Wilson is the division president with the company and Jim Fulton is a project superintendent. One thing remains somewhat similar, however, the quality the company puts into the roads they build, pave, mill and resurface. That remains unchanged and unchallenged.

This essentially was the reason why Barriere was awarded the 1983 National Asphalt Paving Association's prestigious Sheldon G. Hayes award for excellence in roadbuilding and asphalt paving on this project.

One very interesting fact about the project, however, is the cost and quantity differential between the two projects. The original contract with the Louisiana State Highway Department was for $7,098,529 and called for 124,300 tons of asphalt.
