    Abstract
  • In order to evaluate the temperature-lowered effect of Sasobit and its influence on the road performances of asphalt mixture, penetration test and softening point test for asphalt with Sasobit were done, void ratio test, rutting test, bending-beam test and frost thawing and splitting test were done to asphalt mixture samples without Sasobit mixed in normal temperature and with Sasobit mixed in low temperature, and their performances were analyzed. Test result indicates that the high temperature stability of asphalt with Sasobit increases, the changes of the void ratio, crack resistance stability in low temperature and water stability of mixtures with Sasobit are unobvious, but its high temperature stability enhances, it is feasible that the mixing and molding temperatures of asphalt mixture are lowered by using Sasobit.
