Semi-rigid base asphalt pavement structure
The invention relates to the technical field of road engineering construction, in particular to a semi-rigid base asphalt pavement structure which comprises a semi-rigid base. The asphalt pavement bottom layer is paved on the upper surface of the semi-rigid base layer; the asphalt pavement bottom layer is divided into a lateral confinement area, a heavy-load driving area and a plastic flow deformation area along the width direction of the road; the heavy-load driving areas are located on the two sides of the plastic flow deformation area. The lateral confinement areas are positioned on two sides of the heavy-load driving area; the lateral confinement area is used for limiting deformation of the heavy-load driving area due to pressure; the plastic flow deformation area is used for bearing deformation of the heavy-load driving area due to pressure; the asphalt pavement middle layer is paved above the asphalt pavement bottom layer; and the asphalt pavement surface layer is paved above the asphalt pavement middle layer. The asphalt concrete pavement has the effect of reducing ruts on the asphalt concrete pavement.
本申请涉及一种半刚性基层沥青路面结构，涉及道路工程建设的技术领域，其包括半刚性基层；沥青路面底层，铺设于半刚性基层上表面；沥青路面底层沿公路宽度方向分为侧限区、重载行车区和塑流形变区；重载行车区位于塑流形变区两侧；侧限区位于重载行车区两侧；侧限区用于限制重载行车区受到压力发生形变；塑流形变区用于承接重载行车区受到压力发生形变；沥青路面中层，铺设于沥青路面底层上方；沥青路面表层，铺设于沥青路面中层上方，本申请具有减少沥青混凝土路面车辙的效果。
