江淮多雨地区沥青路面坑槽病害内因分析及预防

Internal Causes Analysis & Prevention of Asphalt Pavement Pits Diseases in Jianghuai Pluvial Region

坑槽病害是江淮多雨地区沥青路面最广泛的病害之一。造成这种现象的原因是复杂的,既有材料、设计、施工及养护的原因,也有交通荷载与环境的原因,其中沥青路面的原材料、级配、压实工艺和离析控制对于混合料水稳定性的影响至关重要。结合江淮区域高等级沥青路面的病害,进行坑槽病害成因的分析,并提出相应预防措施。

The pavement pits is one of the broadest asphalt pavement diseases in Jianghuai pluvial region. The causes to this phenomenon are complex including materials,design,construction,maintenance,and moreover,traffic load and environmental reasons. For mixture water stability,raw material,grading,compaction process and segregation control of asphalt pavement are significant. Combined with high class asphalt pavement diseases in Jianghuai region,the analysis of the causes to pavement pits diseases is made and the relevant preventive measures are proposed.
