    Abstract

    Intersections of asphalt pavement are easily destroyed under heavy traffic in spite of several different technologies employed to combat such damage. Traditional high modulus asphalt mixtures were optimized according to the requirement of intersection maintenance. Penetration grade 40/60 base asphalt, an anti-rutting additive, and hard basalt aggregate were used to design a new high rutting resistance asphalt mixture. The air void content, compaction characteristics, water sensitivity, high temperature performance, and low temperature performance were investigated. Laboratory test results show that the new high rutting resistance asphalt mixture has very good high temperature performance and other beneficial characteristics. From the sensitivity analysis of the material composition, it can be deduced that the performance of the new high rutting resistance asphalt mixture is stable. Field tests also show that the new asphalt mixture is suitable for intersection maintenance of asphalt pavement and can be paved in one layer 9 to 14 cm in thickness.
