A hard grade asphalt Pen 10/20 and limestone aggregate are used to produce the high modulus asphalt mixture (HiMAM)-AC20 in this paper. A SBS modified asphalt PG70-22 is compared with Pen 10/20 asphalt. After mix design is finished, the basic properties of this mixture are tested including Marshall Stability, dynamic stability, rutting depth, bending strain, indirect tensile strength ratio and so on. The resilient modulus and complex modulus of hard grade asphalt mixture (HaGAM) are investigated by means of the uniaxial compression test. Three temperatures are adopted for resilient modulus and five temperatures are adopted for complex modulus with the different frequencies. Master curves are constructed by regressions for a sigmoidal function. Cole-Cole plane is used to analyze viscoelastic property of HaGAM. The results indicate that this hard grade asphalt can be used to produce HiMAM with the excellent rutting resistance. Complex moduli of HaGAM are higher than SBS asphalt mixture at the same temperature, but viscous flow of HaGAM is easier than SBS-AM below 37.8℃.
