Recycling Efforts Save VDOT More Than $15M

VDOT is in the process of widening 21 miles of I-64 in the Hampton Roads area with work starting in 2015 and scheduled to finish in 2021. Allan Myers is the contractor of record for Segment II of this work which includes widening to six lanes to support regional growth, traffic to beaches, and port capacity improvements. This seven-mile segment included bridge widening and rehab of existing structures, 19 ramps, 3 interchanges, 4 box culvert extensions, and 17,000 SF of noise wall.

“This is the largest pavement recycling project happening in the country right now,” Brian Diefenderfer, Ph.D., P.E. with the Virginia Transportation Research Council says. “There are two recycling processes being used on Segment II and Segment III; FDR and CCPR. FDR is being used to provide a foundation for the pavement system and the CCPR material is being placed as a base layer.”
The contractor on the project, Allan Myers, had the option to use recycled concrete aggregate or recycled asphalt pavement (RAP) and they chose the concrete in this case.

“Recycled concrete was more readily available in market close to the project,” says Shannon Moody, public relations manager at Allan Myers. “The CCPR for the project also requires a significant amount of RAP that we were not interested in taking from our RAP supply for the FDR.”
Allan Myers is always looking for innovative ways to do business,” Moody says. “The CCPR innovative process and technology was an expertise we were interested in developing for the I-64 Segment II project and future work. In addition, recycled material is advantageous for the environment and economical.”

Wirtgen experts met with operators, quality assurance technicians and superintendents at Allan Myers to train them on the KMA 200 over multiple days. Wirtgen will also send personnel as needed to refresh training and monitor the performance of the equipment to ensure its operating correctly.”
