摘   要 ：重载交通沥青路面对于混合料的级配及材料组成要求较高 ，研究采用 AC- 13 和 SMA- 13 两种不同级配分别制备掺和不掺抗车辙剂的沥青混合料，探究不同级配组成混合料间的性能差异 ，主要考察了沥青混合料的动稳定度 、残留稳定度 、冻融劈裂强度比及劈裂寿命 ，研究表明 SMA- 13 级配沥青混合料的高温稳定性、低温抗裂性及抗疲劳性能较好 ，抗车辙剂材料的加入能整体提升混合料 15%以上的综合性能 ，建议重载交通沥青路面采用 SMA- 13 级配和抗车辙剂 ，可实现重载沥青路面长期的健康稳定发展。

Abstract:Heavy-duty traffic asphalt pavement has higher requirements for gradation and material composition of mixtures. Two kinds of gradation, AC-13 and SMA-13, are used to prepare asphalt mixtures with and without anti-rutting agent respectively, the difference of performance among different gradation mixtures is explored, and the dynamic stability, residual stability, freeze-thaw crack strength ratio and crack life of asphalt mixture are mainly investigated, the results show that the SMA-13 gradation asphalt mixture has good high temperature stability, low temperature anti-cracking and anti-fatigue properties, and the adding of anti-rut agent material can improve the comprehensive properties of the mixture more than 15% , it is suggested that SMA-13 gradation and anti-rutting agent should be applied to heavy-load asphalt pavement to realize long-term healthy and stable development of heavy-load asphalt pavement.

Keywords:gradation design; heavy-duty traffic; road performance; anti-rutting agent
