ACPA Concrete Pavement Progress Q1 2020

Although traffic slowed, which was expected, the need to address traffic accidents or other problems in the lanes led to new traffic control features, he says. “Motorist assistance patrols and access to 24/7 wrecker services helped us move disabled vehicles out of the way sooner,” he adds. Existing pavement was removed, and the old concrete was crushed and re-used with the Class 7 cement-treated base for the new pavement, says Shirley. “The subgrade required soil stabilization and subsurface drainage, which meant a lot of work by the contractor before the pavement could be placed.” The project, which included bridge work, placement of a permanent con- crete median, and construction of six box culverts, beganMarch 2017 and was completed April 2019, says Don Weaver, president of Weaver-Bailey Contractors, Inc., an ACPA member. The 12-in. concrete pavement was placed on a 6-in. cement-stabilized base course, he says. “One of the challenges was change in elevation, with the north end of the project on high ground that went down into wetlands,” says Jonathan Foster, vice president of Weaver Bailey. “This area and the surrounding surface roads typically flood so we built the road up two to five feet higher to lessen the chance of flooding,” he adds. “One of the challenges was change in elevation, with the north end of the project on high ground that went down into wetlands.
