摘要
唐山西外环高速公路沥青混凝土表面层采用SBS改性剂对基质沥青进行现场改性,避免了成品改性沥青的改性剂离析现象,经过一系列的试验和检测表明改性沥青混凝土大大改善了沥青路面的路用性能,延长了沥青路面的使用寿命。
Original asphalt was in-place modified by SBS modifier on asphalt concrete surface course of Tangshan west circumferential expressway.It avoided modifier separation phenomena of modified asphalt product. The test results show that the asphalt pavement performance was enhanced apparently by modified asphalt concrete, which prolonged the longevity of asphalt pavement.
