路面建成后,不论其是水泥混凝土路面,还是沥青混凝土路面,都会产生各种形式的裂缝。初期产生的裂缝对路面的使用性能无明显影响,但随着表面水的侵入,导致裂缝两侧路面结构层,特别是裂缝附近土基的含水量加大,甚至饱和,使路面强度明显降低,在大量行车荷载反复作用下,产生冲刷和唧泥现 After the completion of the pavement, whether it is cement concrete pavement or asphalt concrete pavement, will produce various forms of cracks. However, with the intrusion of surface water, the water content of the pavement structure layer on both sides of the crack, especially the soil near the crack, increases or even increases, so that the road surface strength is obviously reduced, Repeated action in a large number of driving loads, resulting in scouring and jacking mud now
