  要:结合路面养护大中修实体工程,对沥青混合料掺加抗车辙剂前后的路用性能进行了试验研究。结果表明:HXR型抗车辙剂的掺入可显著提高沥青混合料的高温抗车辙性能,对其抗水损害性能有一定的改善效果。路用性能检测表明:添加抗车辙剂的路段各项检测指标均满足公路沥青路面施工技术规范要求,其车辙深度及增加幅度均小于未添加抗车辙剂的路段。

Abstract: Based on the large and medium-sized maintenance project, pavement performance of asphalt mixture before-and-after mixed with anti-rutting agent was studied. The results showed that the rutting resistance of asphalt mixture could be significantly improved by adding HXR anti-rutting agent, and water damage resistance of asphalt mixture was improved. The performance test showed that each detection index of the road adding anti-rutting agent meeted the technical specification requirements of highway asphalt pavement construction, and increasing range of rutting depth were less than the road without agent.

Key words: asphalt mixture; anti-rutting agent; large and medium-sized maintenance project; pavement performance
