Pavement Reflective Cracking Control with Coarse-Aggregate Asphalt Mix Interlayer

A test road was constructed using different asphalt concrete overlay treatments. The field observations conducted after 3 years of the pavement being in service indicated that the coarse-aggregate asphalt mix interlayer worked exceptionally well in reflective crack control. A three-dimensional finite element analysis showed that the main stresses in the coarse-aggregate asphalt mix interlayer were lower than those in the normal asphalt concrete interlayer with the same thickness. It is believed that the large-size aggregates and high air voids in the mixture can block the paths of initial cracks to extend to the top of the interlayer.
