摘　　要：阿尔及利亚东西高速公路经过多年的运营后,沥青路面已经出现裂缝;在初步处理的过程中,通过对沥青路面的裂缝进行分析,考察路基结构,从设计、施工和运营等方面,对沥青路面出现裂缝的可能成因进行研究,对裂缝的预处理和预防等方面进行了论述;积累了经验,为类似的工程提供可能的借鉴作用。After years of operation, cracks have appeared on the asphalt pavement of Algeria East-west Highway. In the process of preliminary treatment, subgrade structure was investigated by analyzing the cracks on the asphalt pavement. Then, the possible causes of cracks on asphalt pavement were studied and pretreatment and prevention for cracks were dis- cussed from the aspects of design, construction and operation. The accumulated engineering experience could be taken as a certain reference for other similar projects.
