摘   要 ：重載交通瀝青路面對于混合料的級配及材料組成要求較高 ，研究采用 AC- 13 和 SMA- 13 兩種不同級配分別制備摻和不摻抗車轍劑的瀝青混合料，探究不同級配組成混合料間的性能差異 ，主要考察了瀝青混合料的動穩(wěn)定度 、殘留穩(wěn)定度 、凍融劈裂強度比及劈裂壽命 ，研究表明 SMA- 13 級配瀝青混合料的高溫穩(wěn)定性、低溫抗裂性及抗疲勞性能較好 ，抗車轍劑材料的加入能整體提升混合料 15%以上的綜合性能 ，建議重載交通瀝青路面采用 SMA- 13 級配和抗車轍劑 ，可實現(xiàn)重載瀝青路面長期的健康穩(wěn)定發(fā)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
