摘要
采用温拌添加剂Sasobit改性而成的温拌橡胶沥青是一种新材料,通过对不同Sasobit掺量下的温拌橡胶沥青进行常规性能、粘度性能以及混合料的高温性能试验,分析Sasobit对温拌橡胶沥青及其混合料高温性能的影响及其规律.试验结果表明:Sasobit的最佳掺量为3%,其降粘效果约为20℃.
Warm-mixed rubber asphalt modified by Sasobit warm asphalt additive is a new material. In order to analyse the influences and laws of the high-temperature performance of warm-mixed rubber asphalt which is im- pacted by Sasobit, regular performance tests, viscosity properties tests, and high-temperature performance tests of mixture with different percent of Sasboit were carried out. Finally, the results showed that the best percent of Sasobit is 3 %, the temperature of reducing viscosity of Sasobit is approximately 20 ℃.
