结合对上海市浦东新区一临近东海的城市道路沥青路面状况的详细调查,描述了沥青路面的损坏类型。其中横向裂缝、车辙和沉陷是沥青路面的主要破坏形式,占到总破坏面积的80.9%。最后分析了产生的原因,提出了今后城市道路在设计和施工中应着重注意的几个问题,并建议在路面施工中应提高沥青压实度标准,在路基施工中应注意采取切实措施确保沟浜回填质量。

Investigation & Analysis on Damage of Urban Road Asphalt Pavement

Combined with a careful investigation of urban road asphalt pavement (close to East China Sea, Pudong Shanghai), the different damage types of asphalt pavement were put forward in the paper. There were main damage types such as transverse cracks, rut and pavement pression, which covered to 80.9% of the total damaged areas. Then, the author made an analysis of damage reasons and applied some related important problems in the future design and construction of urban roads. And the author emphasized that the asphalt compaction criterion should be strengthened, the river backfill quality should be guaranteed during the construction.
