沥青路面养护工程施工平整度质量控制

Construction Smoothness Quality Control of Asphalt Pavement Maintenance Project

据统计,到2019年江苏省高速公路总里程已达到4700余公里,有60%以上运营时间超过10年,同时交通量不断的增长,在行车荷载及环境综合因素作用下,高速公路沥青路面出现空槽、车辙、裂缝等病害,导致路面平整度不足,影响沥青路面行车舒适性及安全性。为了确保沥青路面进行养护的平整度质量,文章结合2019年广靖锡澄高速公路路面集中养护工程实践,从原路面铣刨、沥青混合料生产、沥青混合料摊铺、碾压、接缝处理、质量控制等方面,分析沥青路面养护工程中平整度施工质量控制,并对关键施工环节提出了控制建议,可为同类工程提供借鉴。

According to statistics, by 2019, the total mileage of the expressway in Jiangsu Province has reached more than 4700 km, with more than 60% of the operation time being more than 10 years, and the traffic volume is increasing. Under the influence of the driving load and the environment, the asphalt pavement of the expressway has an empty groove and a rutting. The cracks and other diseases, resulting in insufficient road surface flatness, affect the ride comfort and safety of the asphalt pavement. In order to ensure the quality of the smoothness of the asphalt pavement, the paper combined with the practice of concentrated maintenance in the pavement of the Guangzhou-Jingxi Expressway in 2019, paving, rolling and connecting the asphalt mixture from the original road surface planer, the asphalt mixture production and the asphalt mixture. From the aspects of joint treatment and quality control, this paper analyzes the quality control of smoothness construction in asphalt pavement maintenance engineering, and puts forward some control suggestions for the key construction links, which can be used for reference for the same kind of projects.
