SBS改性沥青混合料路用性能及其施工应用研究OA

In order to study the improvement effect of SBS modifier on pavement performance of asphalt mixture and its construction applica-tion,the paper takes the upper layer of AC-13 SBS modified asphalt concrete pavement of a newly built urban main road as the research ob-ject.Through analysis,it is concluded that asphalt mixture mixed with SBS modifier can significantly improve pavement performance in terms of high stability,low temperature crack resistance and durability.It can adapt to the cyclical effects of adverse factors such as extreme climate and heavy traffic.
