改性剂对沥青胶结料性能指标影响的研究分析

Research and analysis of influences modifier to the performance index of asphalt binder

研究了TPS、路孚8000及Sasobit改性剂对沥青胶结料性能的影响,试验结果表明:三种新型添加剂对高温稳定性均有较大提高,TPS对低温抗裂性也有较大提高,以改善沥青胶结料的高温性能和低温性能。

The influences modifiers TPS, Lufu 8000 and Sasobit to the performance index of asphalt binder were researched. The result showed that three new type modifiers all have great improvement to the high temperature stability arid TPS can enhance crack resistance in low temperature, which can improve the high and low temperature performances,
