| Abstract: | The influence of a new kind of warm mix asphalt additive on viscosity and conventional proper ties of SBS modified asphalt were studied. The optimized conditions of preparation warm mix asphalt as follows ： stirring speed 200 r/rain, stirring time 30 rain ,the pH of warm mix agent solution is 8 and concen tration is 6%. The results showed that a certain degree the warm mix agent can improve the softening point and penetration, ductility variable16ngth, high and low temperature performance of asphalt have been effectively improve and enhance. |
