Sensors have been installed to study the long-term effects on one of the largest paving projects underway in the U.S. to use full depth reclamation and cold central plant recycling.

Virginia Department of Transportation researchers, along with those from the Virginia Tech Transportation Institute and the Virginia Transportation Research Council, installed the sensors this month on a 40-foot section of a new lane for a widened Interstate 64 in York County. The section is part of the third and final segment of the widening.

The second segment, where FDR and CCPR were also used, was completed last year.The goal is to spread the cost-saving FDR and CCPR methods to other road projects in the state by confirming the techniques’ long-term performance, according to the VDOT. The agency says the methods saved $15 million on the second and third segments of the I-64 widening project.

VDOT also touts the environmental benefits of using reclaimed asphalt pavement in the CCPR process, especially as the state has millions of tons of RAP millings stockpiled from previous road projects.
