- Abstract:
- With the fact that plasticizers were used successfully in plastic products to improve the low-temperature flexibility of asphalt binder,two kinds of plasticizer are selected in this paper to study the impact of two plasticizers on asphalt.In this paper,4 different dosages of the two plasticizer totally 8 dosages were put into asphalt to study the performance of asphalt binders by several routine tests including the penetration,softening point,ductility,viscosity,measuring-stress ductility and elasticity resuming.And the modification effect was evaluated in the aspect of temperature sensitivity,high temperature and low temperature,elastic recovery and aging.The test results showed that the plasticizers did help significantly in the low-temperature performance of the modified asphalt binders,also in the facts of temperature sensitivity,anti-aging ability and elasticity resuming,but not in high-temperature performance.In general,the plasticizer DOM was better than DOP in improving the properties of asphalt binders.
