试验分析了一种新型的 SEBS改性沥青和酸性石料的粘接性能 ,通过对比发现 ,SEBS改性沥青与花岗岩酸性骨料的粘附性能与 SBS改性沥青都能达到 4级。使用石灰石作为填料 ,可以明显提高 SEBS改性沥青和酸性花岗岩集料的的水稳定性能 ,使用石灰石填料的 4% SEBS改性沥青混凝土试件残留马歇尔稳定度可以达到浸水前的 84%。
The adhesion of a new kind of SEBS modified asphalt and acid stone was analyzed experimentally. It was found by comparison that the adhesion between SEBS modified asphalt and granite acid aggregate and SBS modified asphalt reached grade 4. The use of limestone as filler can significantly improve the water stability of SEBS modified asphalt and acidic granite aggregate. The residual Marshall stability of 4% SEBS modified asphalt concrete with limestone filler can reach 84% before water immersion.
