摘要
通过模拟SBS改性沥青在生产、施工临时存储时的状况,对改性沥青的针入度、软化点、延度、弹性恢复等主要性能指标进行了全面试验,获得了交替升(降)温时改性沥青的性能衰变规律,并分析了其性能衰变原因。
Simulating the SBS modified asphalt's temporary deposition condition during production and (construction), we have made a (comprehension) test of the important performance indexes including (penetration), softening point, ductility and elastic recovery. Through the test, we have obtained the (performance) decay law of the modified bitumen and analyzed the cause of its alternative temperature change.
