ABSTRACT
Warm mix asphalt mixture, a certain technical measures to reduce the viscosity of asphalt can make asphalt mix at relatively lower temperature than hot mix asphalt. In order to improve the pavement performance, warm mix technology of rubber asphalt mixture were discussed in this study. Then the influence of warm mix agent on the formation of rubber asphalt mixture, ore heating temperature and road performance was analyzed by the test. Results showed that the mix temperature and ore heating temperature were both decreased by 10°C with the use of warm mix agent, Sasobit; at the same time, high temperature performance and fatigue property of the modified asphalt mixture were improved, while the low temperature performance was decreased and the water stability was affected slightly.
