近年来,随着公路交通事业的迅猛发展,我国山区的公路也逐渐增多。由于山区的路比较窄,一旦交通量增长、载重车辆比例增加、车辆超载,山区公路沥青路面便会出现开裂的情况,这也是山区沥青路面的使用质量和寿命达不到应有水平的原因。这种情况如果得不到及时处理,将造成路面水下渗,路面承载力降低。本文将着重探讨山区公路沥青路面的开裂问题,提出山区公路沥青路面开裂的防治对策。 In recent years, with the rapid development of highway transportation, the roads in mountainous areas of our country have also gradually increased. As the roads in mountainous areas are relatively narrow, once the traffic volume increases, the proportion of truckloads increases and the vehicles are overloaded, the asphalt pavement on mountainous roads will be cracked. This is also the reason why the quality and service life of asphalt pavement in mountainous areas are not up to the required level. If this situation can not be dealt with promptly, it will cause the seepage of the road surface and reduce the bearing capacity of the road surface. This article will focus on the cracking of asphalt pavement in mountainous areas, and puts forward some countermeasures to prevent cracking of asphalt pavement in mountainous areas.
