According to LPC Bituminous Mixtures Design Guide, performance of several kinds of additives for high modulus asphalt mixture is evaluated by tests. It has done performance comparison among AC20, Sup20 and EME20 using AH70# asphalt. The results show that high modulus asphalt mixture EME2 has high temperature stability and anti-fatigue capability. The testing results in the article had proved that the existing China-made additives can also meet the requirement of High Modulus Asphalt Concrete (HMAC). The mix design of AC20 and Sup20 was done according to LPC Bituminous Mixtures Design Guide, test results are basically the same as EME20 and meet the design requirement. So it can consider using HMAC which satisfies China’s requirement in China.
