雨季台风季沥青路面施工管理策略及影响分析
Management Strategy and Impact Analysis of Asphalt Pavement Construction during Rainy Season and Typhoon Season

本文以上海市奉贤区G228公路为研究案例，深入研究夏季台风季对沥青路面施工的影响及应对策略。研究发现夏季台风季的降雨会降低沥青与集料的粘结力，致使路面出现麻面、松散等病害，基层含水率过高还会影响防水性能；风速过大会加速沥青混合料热量散失，降低压实度、影响平整度；台风来袭常导致停工，延误工期并增加成本。针对这些问题，本文提出了施工组织调整、防雨防风措施以及加强施工过程控制等管理手段。通过设置防雨棚、防风屏障，调整施工进度和顺序，严格控制混合料温度和施工长度等措施，经对比实践表明，采用综合管理手段的施工段，在压实度、平整度、渗水系数等质量指标上表现优异，工期延误天数大幅减少，为雨季台风季沥青路面施工提供了科学有效的管理策略。
This article takes G228 highway in Fengxian District, Shanghai as a case study to deeply investigate the impact of summer typhoon season on asphalt pavement construction and corresponding strategies. Research has found that rainfall during the summer typhoon season can reduce the adhesion between asphalt and aggregates, leading to road surface defects such as roughness and looseness. Excessive moisture content in the base layer can also affect waterproofing performance; Excessive wind speed can accelerate the heat loss of asphalt mixture, reduce compaction degree, and affect smoothness; Typhoons often lead to work stoppages, delays in construction schedules, and increased costs. In response to these issues, this article proposes management measures such as adjusting construction organization, implementing rain and wind prevention measures, and strengthening construction process control. By setting up rain shelters and wind barriers, adjusting construction progress and sequence, strictly controlling the temperature of the mixture and construction length, and other measures, comparative practice has shown that the construction section using comprehensive management methods performs well in quality indicators such as compaction degree, flatness, and water permeability coefficient, significantly reducing the number of days of project delay. This provides a scientific and effective management strategy for asphalt pavement construction during rainy and typhoon seasons.
