高等级公路沥青路面裂缝病害原因与养护对策研究

Research on the Causes of Cracks in High-Grade Highway Asphalt Pavement and Its Maintenance Countermeasures

高等级公路如果会出现横向裂缝、龟裂、纵向裂缝等不同形式的裂缝病害,严重影响行车安全,因此,有必要对高等级公路沥青路面裂缝病害进行深入研究。结合工程案例,论文通过分析高等级公路沥青路面裂缝的类型以及形成原因,对高等级公路沥青路面养护措施展开研究,并提出针对性的养护对策。

If different forms of crack diseases such as transverse cracks,cracks,and longitudinal cracks will appear on high-grade highways,which will seriously affect the driving safety.Therefore,it is necessary to study the crack disease of high grade highway asphalt pavement.Combined with engineering cases,this paper analyzes the types and causes of cracks in asphalt pavement of high-grade highways,and proposes targeted maintenance countermeasures.
