摘要
通过对高粘度基质沥青(AH-30)、重交沥青(AH-70)及SBS改性沥青混合料进行SST剪切和贯入剪切试验,对比研究了3种不同沥青混合料的高温抗剪性能.结果表明:高粘度基质沥青混合料的高温抗剪性能优于重交和改性沥青混合料,抗高温车辙能力明显,可适用于南方湿热地区沥青路面中下面层.
Superpave Shear Test and Uniaxal penetration test are carried on high viscosity asphalt based mixture, asphalt mixture for paving heavy traffic road and SBS modified asphalt mixture, contrasting to study the difference of three kinds of different mixtures in shear resistance to high temperature. The result shows that： high viscosity asphalt based mixture is better than normal asphalt based mixture for paving heavy traffic read and SBS modified asphalt mixture in aspect of shear resistance to high temperature, which can be applyed to the southern hot and damp region, and this can produce a good social and economic performance.
