西藏地区沥青路面裂缝类病害特征研究

Research on Characteristics of Asphalt Pavement Cracks in Tibet Region

由于西藏地区沥青路面受到特殊的气候环境与地质的作用,沥青路面病害形式复杂多样且路面性能衰减速率快。通过对西藏典型区域沥青路面病害调研,分析了西藏地区沥青路面裂缝类病害的特征,以横向裂缝、纵向裂缝、不规则裂缝3类形式为主探讨了沥青路面裂缝类病害所占比例,介绍了裂缝类病害的常见处治措施,并提出了裂缝类病害的基本处治步骤。

As a result of special climatic environment and geological conditions, the damage forms of asphalt pavement in Tibet are complex and varied, and the pavement performance attenuates by a fast rate. Through the investigation and study of typical asphalt pavement diseases in Tibet, the characteristics of asphalt pavement cracks were analyzed. The proportion of cracks in asphalt pavement was discussed, including the transverse cracks, longitudinal cracks and irregular fractures. The common treatment measures of crack diseases were introduced, and the basic treatment steps of crack diseases were put forward. The study provides reference for the construction and maintenance of asphalt pavement in Tibet.
