抗车辙剂在城市主干路沥青路面施工中的应用研究——以栖霞区马高路北延道路建设工程为例

Research on the Application of Anti Rutting Agent in theConstruction of Urban Main Road Asphalt Pavement—Taking the North Extension Road Construction Project of Magao Roadin Qixia District as an Example

为解决城市道路的车辙问题,节约养护维修成本,延长道路使用寿命,围绕抗车辙剂作用机理、抗车辙沥青混合料配合比设计以及施工工艺等方面展开了抗车辙剂在城市主干路沥青路面施工中的应用研究。研究结果表明:抗车辙剂的加入可以有效改善沥青混合料的高温抗变形能力;路面长期性能跟踪观测结果显示,掺加抗车辙剂的沥青路面具有更小的车辙深度以及更好的长期服役性能。抗车辙剂将在我国城市道路中具有广阔的应用场景。

In order to solve the problem of rutting on urban roads,save maintenance costs,and extend the service life of roads,the article conducts research on the application of anti rutting agents in the construction of urban main road asphalt pavement,focusing on the mechanism of action of anti rutting agents,the design of anti rutting asphalt mixture proportions,and construction techniques.The research results indicate that the addition of anti rutting agents can effectively improve the high-temperature deformation resistance of asphalt mixtures.The long-term performance tracking observation results of the road surface show that the asphalt pavement with added anti rutting agent has smaller rut depth and better long-term service performance.Anti rutting agents will have broad application scenarios in urban roads in China.
