常见路面反射裂缝处治措施分析与评价

Analysis and Evaluation on Treatment Measures for Common Pavement Reflective Crack

高速公路沥青路面反射裂缝类病害是路面最常见的病害,目前经常采用的有开槽灌缝、抗裂贴、玻纤格栅、聚酯玻纤布、条形挖补五种裂缝处治措施。原有路面的裂缝在进行处治后,何时反射至加铺罩面层,发展的速度如何,均没有明确的定义,而只是靠管理者的经验来判定。详细介绍了几种路面裂缝处治措施,对不同处治措施的实际处治效果进行评价,从裂缝出现、裂缝发展进行全过程分析,重点分析了不同处治措施对于裂缝抑制的效果、裂缝发展的速度以及发展趋势,推测出不同处治措施的使用寿命。

The reflective crack of asphalt pavement on expressway is the most common disease of pavement.At present,five treatment measures are often adopted,including grooving and joint grouting,crack resistant paste,glass fiber grid,polyester glass fiber cloth and strip patching.There is no clear definition for the problem when the cracks on the original pavement will be reflected to the overlay after treatment or how fast they will develop.But it only depends on the experience of the manager.The actual treatment effects of different treatment measures are evaluated,the whole process analysis of crack occurrence and development is made,and the effects of different treatment measures on crack inhibition,crack development speed and development trend are emphatically analyzed,so as to speculate the service life of different treatment measures.
