基于疲劳裂缝沥青路面的防治技术措施

Technical measures for prevention and control of Asphalt Pavement Based on fatigue crack

随着国民经济的快速发展,交通量日益增大,道路承受的车辆反复荷载、重载现象日益突出。由于沥青路面长期暴露在大气环境之中,不仅要经受行车荷载的往复作用,而且还要经受气温的循环作用。所以沥青路面在车辆荷载和温度的重复作用下,产生疲劳裂缝。本文从路基施工、路面施工以及养护方式出发,分析沥青路面产生疲劳裂缝的防治措施。

With the rapid development of the national economy and the increasing traffic volume, the repeated load and heavy load of vehicles under the road are becoming increasingly prominent. Because asphalt pavement is exposed to the atmospheric environment for a long time, it not only has to bear the reciprocating effect of traffic load, but also has to undergo the circulation of temperature. Therefore, the fatigue cracks occur on the asphalt pavement under the repeated action of vehicle load and temperature. Based on the roadbed construction, pavement construction and maintenance methods, this paper analyzes the prevention measures for fatigue cracks on asphalt pavement.
