摘要
针对江苏高速公路上、中面层广泛使用SBS改性沥青的情况。从通车已经5年的江苏某高速公路利用切割机、风镐挖取上面层沥青混合料,用旋转法沥青回收仪回收老化沥青,并加添加剂后进行各种性能测试,试验表明,加9%的A1型添加剂后,沥青再生可满足规范要求。
Based on the application of SBS modified asphalt in.the upper and mid-course of asphalt pavement of express highway in Jiangsu province,this paper studied the recovery of SBS modified asphalt of Jinghu expressway(Huai'an section) with cutting machine or air pick,and various tests on the recovered asphalt were conducted by rotation method.The test resnlts showed that modified asphalt can satisfy standard requirement after adding 9%recycling agent in it
