摘要
通过室内试验,对新型高聚合物改性沥青混凝土性能进行评价,结果表明,新型高聚合物改性沥青混凝土高温稳定性、低温抗裂性、水稳定性及抗疲劳性能均明显优于SBS改性沥青混凝土,可明显提高沥青路面的抗反射裂缝能力。为验证其抗疲劳性能,选择了基层开裂比较严重的高速大修路段进行试验段铺筑。
Through the indoor test of a new high polymer modified asphalt concrete performance was evaluated. The test results show that the new high polymer modified asphalt concrete high temperature stability, low temperature crack resistance and water stability and anti fatigue performance is significantly better than that of SBS modified asphalt concrete, can significantly improve the reflective cracking resistance of asphalt pavement. In order to verify its anti fatigue performance, the test section was selected for the high speed overhaul of the base cracking.
