| 摘 要： | 以AC-16混合料的3种级配为研究对象,通过室内车辙试验分析了3种级配在不同SBS改性剂掺量下的高温稳定性。分析结果表明:随着SBS改性剂掺量的增加,沥青混合料的动稳定度DS会明显增大,车辙深度RD会明显减小;较粗集料的沥青混合料的动稳定度明显高于较细集料沥青混合料的动稳定度。

| Abstract: | Based on the wheel tracking test in laboratory,three types of mixtures are used to study Styrene Butadiene Styrene(SBS) modifier on high temperature performance of AC-16 asphalt mixture.It is shown that Rutting Depth(RD) would reduce and Dynamic Stability(DS) would increase obviously with the increasing of SBS modifier,the DS of the coarser asphalt mixtures would be larger than that of the finer mixtures. |
