该文对上海市高等级水泥混凝土路面加铺沥青混凝土工程中的评价、材料、设计、施工等的组织与管理技术进行探讨。结合国家的相关规范与上海市的实际状况,通过详细的分析,明确了上海市旧水泥混凝土路面的调查内容和评价标准;根据评价结果建议了不同的加铺对策,对旧水泥混凝土路面应采用合理的利用方案,对损坏较严重的路面优先考虑采取高性能沥青混凝土的加铺对策;遵循可持续发展的理念给出了高等级水泥混凝土路面加铺工程的特点和施工组织原则,明确了交通组织和质量控制的指导思想,以及各施工环节的工艺要求。以沪青平公路改扩建一期工程为例,详细分析了高等级水泥混凝土路面加铺工程的实施过程和要求。跟踪观测表明,该工程的实施效果良好,所采取的加铺技术方案合理、可行。

This paper discusses the organization and management of evaluation, material, design and construction in the high-grade cement concrete pavement overlaying asphalt concrete project. According the national specifications of China and the local consideration of Shanghai, the paper defines the investigation contents and evaluation standards of the local old cement concrete pavement. Based on the evaluation result, the paper proposes the different overlaying countermeasures. The reasonable utilization scheme is used for the old cement concrete pavement. The high-performance asphalt concrete overlaying countermeasures are firstly used for the more seriously damaged pavements. Following the sustainable development concept, the paper describes the characteristics of the high-grade cement concrete pavement overlaying engineering and its construction organization principle, and defines the guiding ideas of traffic organization and quality control, and the technological requirements of each construction link. The paper analyzes the construction process and requirements of high-grade cement concrete pavement overlaying engineering in detail by the Huqingping Highway Reconstruction Extension Phase I project. The observation shows that the implementation effect of this project is excellent, and the adopted overlaying technical scheme is reasonable and feasible.
