Highway roadbed structure capable of preventing roadbed softening and cooling asphalt pavement
The expressway roadbed structure comprises a roadbed, a gravel layer and an asphalt pavement layer which are sequentially arranged from bottom to top, the roadbed is located on the foundation, and embankments are arranged on the two sides of the roadbed, the gravel layer and the asphalt pavement layer respectively. A plurality of water guiding grooves are formed in the gravel layer at intervals along the highway, the water guiding grooves are formed in the width direction of the highway, the two ends of each water guiding groove are connected with downward-inclined water discharging grooves correspondingly, and the tail ends of the water discharging grooves are connected with a drainage system located in the embankment. Low partition plates are vertically arranged at the two ends in the water guide grooves respectively, so that water storage grooves are formed in the lower portions of the water guide grooves, first water absorption layers are laid at the bottoms in the water storage grooves, gravel supporting plates are horizontally arranged on the upper portions of the water guide grooves and the lower water grooves, a plurality of water filtering holes are formed in the gravel supporting plates at intervals, and second water absorption layers are laid in the gravel layer above every two adjacent water guide grooves; the two sides of the second water absorption layer are connected with the first water absorption layers in the two adjacent water guide grooves through a plurality of water absorption strips arranged at intervals.
本发明公开了一种可防路基软化并能对沥青路面降温的高速公路路基结构，包括由下往上依次设置的路床、砂石层和沥青路面层，路床位于地基上，路床、砂石层和沥青路面层的两侧分别为路堤，砂石层内沿高速公路沿线间隔设有若干导水槽，导水槽沿高速公路宽度方向设置，导水槽的两端分别连接有倾斜向下设置的下水槽，下水槽的末端连接位于路堤内的排水系统，导水槽内两端分别竖直设有低矮隔板使导水槽下部形成储水槽，储水槽内底部铺设有第一吸水层，导水槽和下水槽的上部水平设有砂石支撑板，砂石支撑板上间隔设有若干滤水孔，相邻两导水槽上方砂石层内平铺设有第二吸水层，第二吸水层的两侧分别通过若干间隔设置的吸水条与相邻两导水槽内的第一吸水层连接。
