沿江通道地面富锦路(江杨北路–牡丹江路)沥青砼施工现场质量控制
The Quality Control of Asphalt Concrete Construction Site of Fujin Road (Jiangyang North Road-Mudanjiang Road) along the Ground Level of Yangtze River

本文以上海沿江通道地面富锦路(江杨北路–牡丹江路)工程为例，研究了沥青砼施工现场质量控制的关键点及其控制效果；通过对摊铺速度控制、碾压次数控制、混合料料温控制和接缝质量控制四项质量控制点进行定量控制研究，分析了不同工程段落所得到的实施效果。结果显示，摊铺机的行驶速度主要影响沥青面层的压实度和平整度，本工程的最佳混合料温度参数为初压温度不低于125℃，复压温度不低于100℃，终压温度不低于65℃之间；若是改性沥青砼，温度要求增加15~20℃；并对碾压遍数和冷接缝的处理均提出了严格的质量控制方案，最终施工完成后的沥青路面压实度、渗水系数、平整度三个指标有了显著提高，舒适性和安全性得到了有力保障。
In this paper, taking the Fujin Road (Jiangyang North Road-Mudanjiang Road) project along the ground level of Yangtze River in Shanghai as an example, the key points and control effects of quality control in asphalt concrete construction site were studied. Through quantitative control research on four quality control points: paving speed control, rolling frequency control, mixture temperature control, and joint quality control, it analyzes the implementation effects obtained in different engineering sections. The results show that the driving speed of the paver mainly affects the compaction and flatness of the asphalt surface layer. The optimal temperature parameters for the mixture in this project are the initial compaction temperature of not less than 125？C, the re-compaction temperature of not less than 100？C, and the final compaction temperature of not less than 65？C; if it is modified asphalt concrete, the temperature is required to be increased by 15~20？C; and strict quality control plans were proposed for the treatment of the number of rolling passes and cold joints. After the final construction was completed, the compaction degree, water permeability coefficient, and smoothness of the asphalt pavement were significantly improved, and comfort and safety were effectively guaranteed.
