EVALUATING THE RESISTANCE TO REFLECTIVE CRACKING OF ASPHALT MIXTURES IN SOUTH CHINA

Abstract

Reflective cracking is one of the common problems faced with the asphalt overlay on an existing concrete road. The key to prevent reflective cracking is mainly depending on the performance of asphalt mixture. But now there is not still a simple and facile method and an index to evaluate reflective cracking resistance of asphalt mixture. This paper brings forward impact tenacity as an index and validates it by the simulating test. According to this principle we can design FAC asphalt mixture that is feasible and validated by trial road
