摘　　要：为探究寒冷地区沥青路面典型病害,对寒冷地区不同等级公路的沥青路面病害进行了全面的调查分析。调查结果表明:对于寒冷地区的沥青路面,普通公路典型病害为裂缝类,高速公路虽然修补所占比例较大,但裂缝类病害仍不能忽视;对寒冷地区公路裂缝类病害进行整理,发现寒冷地区公路裂缝类病害主要以横向裂缝为主;分析了高速公路修补所占比例较大以及裂缝类病害产生的原因,为寒冷地区沥青路面养护提供了指导。In order to study the typical diseases of asphalt pavement in cold region,the asphalt pavement diseases in different grades of highway in cold area were investigated. Survey shows： For the asphalt pavement in cold area,the typical diseases of common highway are cracks,and the expressway have a large proportion of repaired,but cracks cannot be ignored. Based on the analysis of highway cracks in cold regions,it is found that the main road cracks in cold regions are mainly transverse cracks. This paper analyzes the reasons for the large proportion of highway repair and the causes of cracks,and provides guidance for the maintenance of asphalt pavement in cold areas.
