Abstract：High modulus asphalt concrete (abbrev. HMAC) is a new pavement material，which improves high temperature
stability by increasing elastic modulus. HMAC is evaluated，which is prepared through adding PR Modulus additive to asphalt
mixture. The results show that high modulus asphalt concrete which adding PR Module additive to asphalt mixture can improve
high temperature stability of asphalt concrete pavement， constant low temperature crack resistance， water stability of
performance has improved，and according to analysis of dynamic modulus tests data，the rutting can be reduced greatly by
increasing the elastic modulus of the asphalt mixture.
