沥青路面在使用期间开裂是世界各国普遍存在的问题,路面裂缝本身的危害并不大,但从裂缝不断渗入到路面结构中的水会使基层甚至路基软化,导致路面承载力下降,产生唧浆、台阶、网裂,加速路面破坏。因此,如何采取有效措施,提高路面的抗裂性能是世界各国公路专家都共同关注的问题。下面笔者结合辽宁省部分高速公路存在的一些裂缝情况,谈谈北方高速公路裂缝这种病害产生的原因及
Asphalt pavement cracking during use is a common problem in all countries in the world, the damage of pavement crack itself is not great, but the infiltration of water into the pavement structure through cracks will soften the grassroots or even subgrade, causing the bearing capacity of pavement to drop, , Steps, net crack, accelerate pavement damage. Therefore, how to take effective measures to improve the crack resistance of pavement is a common concern of highway experts all over the world. Now I combine some of the existing highway in Liaoning Province, the situation of some cracks, to talk about the Northern Highway Freeway crack the cause of the disease and
