0.引言随着我国经济迅速发展,高等级公路及高速公路多以沥青路面为主,裂缝作为沥青路面常见的病害之一,对我国经济和人民生活产生了较大影响,必须引起广泛关注。裂缝从产生到发展都会对路面产生一系列严重的危害,首先影响行车舒适性和路面美观,严重时甚至会危及行车安全,其次雨水或积水渗入路面底层甚至到达基层后,在行车荷载的反复作用下会对沥青混合料产生冲刷作用使路面结构承载力下降,同时也会改变路面结构的受力模式,加速路面的整体破坏,使

Cracks, as one of the common diseases of asphalt pavement, have a great impact on the economy and people’s livelihood in our country and must be widely concerned. Crack from generation to development will have a series of serious damage to the road, first of all affect the comfort and road appearance, in serious cases even endanger traffic safety, followed by rain or stagnant water into the ground and even after reaching the grass-roots level, in the repeated driving load As a result, the asphalt mixture will be washed out to reduce the bearing capacity of the pavement structure, and at the same time, the stress mode of the pavement structure will be changed to speed up the overall damage of the pavement.
