硬质沥青混凝土疲劳性能研究

Study of Hard Asphalt Concrete Fatigue Performance

疲劳裂缝是沥青路面常见的一种破坏形式。该文结合交通部重载交通长寿命沥青路面关键技术研究项目,针对硬质沥青混凝土的疲劳性能,作了相关的试验与分析,为半刚性路面的抗疲劳研究提出了参考性建议。

The fatigue crack is a destroying form commonly on the asphalt pavement. Combined with the key technical study project of the long service life asphalt pavement of the heavy-load traffic by the Ministry of Communication and in the light of the fatigue performance of hard asphalt concrete,the article introduces the relative experiments and carries out the relative analysis to provide the referring suggestion for the anti-fatigue study of half-rigidity pavement.
