摘要
以某沥青混凝土路面道路交叉口转弯处的病害为例,分析了道路转弯处沥青混凝土路面破损的各种原因.通过对实际发生问题的研究,认为通过采取一些相应的措施可以预防和减少沥青混凝土路面车道转弯处的损坏.主要措施有:处治上应从改善车道转弯处路面结构入手,采用抗剪强度高的路面结构,提高抗变形能力;加强施工管理,确保路面施工质量;对通过交叉口附近的车辆进行限载、限速.
As an example of the damage of an asphalt concrete pavement at the intersection, the reasons of damage were researched at the turn comer. The experimental results shows that it need enhance the shear strength of the pavement structure, and improve resistance to deformation at the intersection of the roads. While it also need strengthen construction management. In addition, vehicles near the intersection shoud be load limit and speed limit. The engineering practices show that the damage of the asphalt concrete pavement lane comer can be prevented and reduced.
