309国道大纵坡路段抗车辙沥青路面施工技术

On construction technique of anti-rutting asphalt roadbed at longitudinal slope section along No.309 national road

针对重载交通大纵坡路段易出现的车辙病害问题,以309国道临汾刘村至吉县窑曲段改建工程为例介绍了抗车辙沥青混凝土路面施工技术,分别阐述了抗车辙沥青混凝土的配合比设计、施工工艺,检测结果表明抗车辙沥青混凝土的高温稳定性能优良,值得推广。

According to the common rutting disease along the heavy traffic longitudinal slope section,the paper introduces the construction technique of anti-rutting asphalt roadbed by taking the reconstruction project of Yaoqu section of No.309 national road from Liucun to Jixian of Linfen as the example,illustrates the mix proportion design and the construction craft of the anti-rutting asphalt concrete,and proves by the test results that the high-temperature stability of the anti-rutting asphalt concrete is better,so it can be further extended.
