A Follow Up Evaluation of the Concrete Pavements (US 58) Rehabilitated in 2012

About the project:

The Virginia Department of Transportation (VDOT) usually rehabilitates old concrete pavements with an asphalt overlay making them a composite pavement. In 2012, a portion of US 58 west in Southampton County received two additional treatment options: a bonded concrete overlay and an unbonded concrete overlay. Around the same time, the eastbound lanes of the same area received the traditional treatment of an asphalt overlay. This provided an opportunity to compare the performance of all three treatment options. US 58 is a four-lane divided primary highway built in 1988 with an 8-in-thick continuously reinforced concrete pavement. VTRC will evaluate the performance of these sections after 12 years of traffic. This evaluation will include visual observation of surface distresses, reviewing district maintenance records, examining VDOT pavement management system condition ratings, and reviewing falling weight deflectometer test results to measure the structural health of the pavement.
