SBS改性沥青SMA混合料在淮盐高速公路的应用研究

Application of SBS Modified Asphalt SMA Mixture in Huai′an-Yancheng Highway

以江苏省淮安(淮)—盐城(盐)高速公路HY22标为例,对SBS改性沥青SMA混凝土的高温抗车辙性能、低温抗裂性能和水稳定性进行试验分析,结果表明,SBS改性沥青SMA混合料具有良好的路用性能,是一种值得推广的沥青路面材料。

Taking Jiangsu provincial Huan＇an-Yancheng highway HY22 for example, analysis on the performance of high temperature ant-track, low temperature ant-crack and moisture stability of SBS modified SMA mixture was put forward. The experimental result shows that SBS modified SMA mixture has good road performance and is worth popularizing as asphalt pavement material.
