Surface retexturing, rejuvenation boost N.C. interstate performance

Faced with a lack of funding, Division 3 of the North Carolina Department of Transportation decided to use a process - surface retexturing coupled with asphalt binder rejuvenation using a maltene-binder rejuvenator -that was less extreme than the initial idea to mill and replace the open graded friction course. New specifications were developed, and the process met the requirements to improve surface friction for safety, as well as macro texture for improved transverse water low and a reduction in hydroplaning, as well as correction of in-place asphalt binder rheology for lifecycle extension and durability. Details of the project are presented here.
