城市道路沥青路面养护维修方案研究

Study on Maintenance and Repair Scheme for Asphalt Pavements of Urban Roads

摘要:

为应对城市道路养护需求日益增长、结构性能要求提高以及夜间施工窗口受限等问题，依托上海市某次干道沥青路面养护维修工程，结合路面病害分布、交通运行特征与施工组织要求，系统开展适用于不同路段条件的沥青路面养护维修方案研究。针对不同区域进行了差异化的养护维修方案：上面层材料基于经济和性能的平衡保障，分区域选择了经济合理的面层材料；基层补强方案中，根据车辆类型、交通影响和施工时间等条件因地制宜选择了4种不同道路基层补强方案，有效平衡工程造价、寿命和交通影响等因素，可为城市道路精细化、高效能的养护方案设计提供有益参考。

Abstract:

To address the increasing demand for urban road maintenance, the rising requirements for structural performance, and the limited construction windows at night, relying on a secondary arterial road asphalt pavement maintenance and repair project in Shanghai, and combined with the pavement disease distribution, traffic operation characteristics and construction organization requirements, a systematic research is conducted on the maintenance and repair schemes of asphalt pavement suitable for the different road sections. For the different areas, the differentiated maintenance and repair schemes are implemented. Based on the balance guarantee of economy and performance, the economical and reasonable surface material is regionally selected for the upper layer material. In the base reinforcing scheme, based on the conditions of vehicle types, traffic impact and construction time, four different reinforcing schemes for road base are selected according to the local conditions, which effectively balance the engineering cost, service life, traffic impact and the other factors, and can provide the valuable reference for the design of refined and high-effect maintenance and repair schemes of urban roads.
