灌入式复合沥青路面在交叉口车辙防治中的应用

Application of poured composite asphalt pavement in prevention and control of rutting at intersections

灌入式复合沥青路面是在基体沥青混合料中灌注特殊浆剂而形成的一种路面结构,结合城市旧路提升改造实践,对灌入式复合沥青路面在城市道路交叉口车辙病害防治中的应用进行研究。研究表明,由于灌入式复合沥青路面的特殊结构形式,使得其在重载交通路况下抗车辙效果显著,减轻了因车辆的急停及起步而导致的车辙、推移等病害。灌入式复合沥青路面能延长道路使用寿命,对节约城市道路维修资金具有积极作用。

Poured composite asphalt pavement is a pavement structure formed by pouring special slurry into the matrix asphalt mixture.Combining with the practice of upgrading and reconstructing old urban roads,the prevention and treatment of rutting disease of poured composite asphalt pavement at urban road intersections is carried out application in research.Studies have shown that due to the special structure of the poured composite asphalt pavement,it has a significant anti-rutting effect under heavy-duty traffic conditions,and reduces the rutting,moving and other diseases caused by the sudden stop and start of the vehicle.The pouring composite asphalt pavement can prolong the service life of the road,and has a positive effect on saving urban road maintenance funds.
