Indoor and field test studies were carried out on the mechanical properties of high-modulus asphalt concrete (HMAC) with special admixture PR Module. The test results show that the external admixture increases the rebound modulus value of asphalt concrete material by 45% and the dynamic modulus by more than 77%, while the test results of the on-site drop weight deflection meter (FWD) show that the comprehensive modulus of high-modulus asphalt concrete pavement is higher than that of SBS modified asphalt pavement, and the external admixture is a good choice to improve the overall bearing capacity of the pavement structure.
