随着山区公路建设的发展,特别是近几年山区农村公路的大规模建设,山区公路沥青路面出现的层间滑移、开裂等病害日益引起大家的重视。其原因主要在于车辆荷载的剪应力和路面结构两个方面。车辆荷载方面,山区公路一般路线纵坡大,变坡较为频繁,弯道较多,而且长大纵坡特别多。弯道多、变坡多会造成车辆的频繁刹车和启动,从而产 With the development of mountain highway construction, especially the large-scale construction of rural road in mountainous area in recent years, the diseases such as interlayer slip and cracking occurred in asphalt pavement of mountainous highway have aroused people’s attention day by day. The main reason is that the vehicle load shear stress and pavement structure in two aspects. In terms of vehicle load, the general length of the mountainous road is large, the slope is more frequent, the corners are more, and the length of the vertical is particularly large. More corners, change the slope will cause frequent braking and start the vehicle, which produces
