Abstract:Due to their high performance, composite pavements have been used by highway agencies as a cost-effective alternative for high traffic volume roadways. In the North Carolina Department of Transportation (NCDOT) Pavement Management System (PMS), however, a function to allow engineers to select the composite pavement as the optimal pavement alternative for a project is lacking. The reason is that, historically, composite pavements have been classified as conventional asphalt pavements in North Carolina, even though these two types of pavements probably perform differently. This study was conducted to address this issue. Researchers identified composite pavement sections in the PMS, developed distress models and performance models for composite roadway families, and determined triggering distresses and recommended appropriate treatments. The findings of this study will help NCDOT engineers to build a new composite pavement maintenance system that can be added to its PMS. This new system, together with the existing asphalt and JCP systems, can provide engineers with a wider selection of pavement types and allow them to recommend appropriate treatments for maintenance and rehabilitation activities.
