摘　　要：0引言公路或城市道路达到其结构寿命年限时就会产生裂缝、拥包、坑槽等病害,从而影响行车的舒适性甚至安全。若不及时修补,路表水很容易淤积在坑槽内,使下面层长期被积水浸泡,出现材料松散、剥落,从而形成更深、更大的坑槽。若积水渗入路面基层,则会使基层材料软化,路面的整体承载能力大幅下降,导致沥青混凝土路面出现严重的结构性破损。而且,沥青混凝土路面一旦出现坑槽破坏,坑槽边缘和底部材料受到骤增的车辆冲击荷载作用,会加速坑槽破损的进一步扩展。所以,Three main methods for patching potholes on asphalt pavement were expouned,including cold material patching,hot material patching and hot recovery patching.The effect degrees of different patching methods to the repair quality were discussed.The results show that the patching methods of excavating pit and filling with regular material are still the best way to choose at the current technical level and personnel situation.
