Expressway roadbed structure capable of preventing roadbed softening
The invention discloses an expressway roadbed structure capable of preventing roadbed softening. The roadbed structure comprises a roadbed a water collecting tank, a drainage channel and a closed conduit, wherein the roadbed comprises an asphalt mastic macadam mixture pavement layer; a medium-grained asphalt concrete layer is arranged at the lower end of the asphalt mastic macadam mixture pavementlayer; a coarse-grained asphalt concrete layer is arranged at the lower end of the medium-grained asphalt concrete layer; a cement stabilized macadam base layer is arranged at the lower end of the coarse-grained asphalt concrete layer; a cement stabilized gravel subbase layer is arranged at the lower end of the cement stabilized macadam base layer; and a compacted soil base layer is arranged at the lower end of the cement stabilized gravel subbase layer; the water collecting tank is arranged in the compacted soil base layer; the drainage channel is mounted at the lower end of the water collecting tank; and the closed conduit is arranged at the lower end of the drainage channel. The roadbed structure realizes prevention and treatment of expressway roadbed softening.
本发明公开了一种可防路基软化的高速公路路基结构，包括：路基，且路基包括沥青玛蹄脂碎石混合料路面层，所述沥青玛蹄脂碎石混合料路面层的下端设置有中粒式沥青混凝土层，所述中粒式沥青混凝土层的下端设置有粗粒式沥青混凝土层，所述粗粒式沥青混凝土层的下端设置有水泥稳定碎石基层，所述水泥稳定碎石基层的下端设置有水泥稳定砂砾底基层，所述水泥稳定砂砾底基层的下端设置有压实泥土基层；集水槽，其设置在所述压实泥土基层的内部；排水道，其安装在所述集水槽的下端；暗渠，其安装在所述排水道的下端。其实现了对高速公路路基软化的防治。
