It is the commonly used technology by adding High Modulus Asphalt Modifier to improve the properties of modified asphalt in road construction. The main function of high modulus asphalt modifier is to improve the performance of asphalt concrete by improving the properties of asphalt binder. There was a little research about the High Modulus Asphalt Modifier effect on the properties of asphalt binder; more research is about the performance of asphalt concrete. It is necessary to predict the

The effect of high modulus asphalt modifier on the properties of asphalt binder was studied in the paper. The experimental results show that as the high modulus modifier adding ratio is increased, the penetration of the blending asphalt, softening point, and the viscosity of the asphalt at 76˚C increase, and there is little change about viscosity at 135˚C. Adding the high modulus asphalt modifier reduces the toughness of asphalt mixture and the ductility, and improves the penetration index of the asphalt.
