Virginia Department of Transportation (VDOT)RICHMOND, Va. (AP) _ The Virginia Department of Transportation says an environmentally friendly pavement used to rebuild a section of Interstate 81 is holding up to the test of time and tires. VDOT says the $10.2 million project was conducted in Augusta County three years ago. The department used three pavement recycling processes to rehabilitate a 3.6-mile portion of the southbound lane of the interstate. VDOT Commissioner Charlie Kilpatrick says the I-81 project demonstrates that pavement recycling is viable on high-volume, high-priority routes. VDOT says the process also saved millions of dollars by recycling existing road material. A report says VDOT should use the pavement recycling method “where it is most suitable.”
