温州代表性市政道路的路面车辙分析及其防治建议

Analysis of Road Ruts on Representative Municipal Roads in Wenzhou and Suggestions for Prevention and Control

摘要: 市政道路运营方面最为凸显的就是车辙问题，其对路面质量以及车辆行驶的安全带来很大影响。本次挑选了温州具有代表性的数条道路进行调查并分析车辙情况，对其展开钻芯取样，对车辙出现的原因进行深入分析。并以此作为参考，对各种路面结构车辙创建相应的计算模型，主要探究轴重和温度对车辙产生的影响。通过所得结果可以看出，城区道路交通中存在一定的超载量，且它与车辙深度之间呈正相关关系，伴随着路面厚度的不断加大，温度对车辙也呈现出明显的正相关关系；与单独荷载这一原因相比，荷载与温度耦合前提下驾车者深度增幅平均达到22%；最后根据模型研判结果，从增强交通疏导、优化级配设计、混合料抗车辙剂的使用以及交通渠化区域洒水降温四个方面提出了车辙预防性建议。

Abstract: The most prominent issue in the operation of municipal roads is the issue of ruts, which has a significant impact on road quality and vehicle safety. This time, several representative roads in Wenzhou were selected for investigation and analysis of rut conditions. Drill core sampling was conducted on them to conduct an in-depth analysis of the causes of ruts. And as a reference, create corresponding calculation models for various road structure ruts, mainly exploring the impact of axle load and temperature on ruts. From the results obtained, it can be seen that there is a certain amount of overload in urban road traffic, and it is positively correlated with the depth of ruts. With the continuous increase of road thickness, temperature also shows a significant positive correlation with ruts; compared with the single load, the average increase in driver depth under the coupling of load and temperature reached 22%; finally, based on the model analysis results, preventive suggestions for ruts were proposed from four aspects: enhancing traffic diversion, optimizing grading design, using anti-rutting agents for mixtures, and watering and cooling in traffic channelization areas.
