Developing a Quantitative Rating System for Continuously Reinforced Concrete Pavement

Abstract

A jointed concrete pavement rating system based on sampling and quantitative surface distress data was developed several years ago for North Carolina. This rating system has been adopted by the pavement management system for the priority ranking of projects. The first attempt to develop a similar rating system for continuously reinforced concrete (CRC) pavement was made with no fruitful results. There remains an urgent need for a comparable CRC rating system for project ranking. Another attempt that used a different approach was made. A linear regression equation was developed, and the correlation with experts’ rating was reasonably good.
