Highway bridge compression-resistant roadbed
The invention discloses a highway bridge compression-resistant roadbed which comprises a soil base layer, a concrete layer, a stabilizing layer, a reinforcing layer, a geotechnical cloth layer, a waterproof geomembrane layer and a surface layer, the soil base layer is located below the concrete layer, the concrete layer is located below the stabilizing layer, the stabilizing layer is located below the reinforcing layer, the reinforcing layer is located below the geotechnical cloth layer, the geotechnical cloth layer is located below the waterproof geomembrane layer, and the waterproof geomembrane layer is located below the surface layer; the soil base layer is prepared from the following components in parts by weight: 20 to 30 parts of lime, 15 to 20 parts of coal ash, 20 to 25 parts of clay, 30 to 50 parts of lime soil and 1 to 3 parts of grit. The overall compression resistance and shock resistance of the roadbed are improved, microcracks are prevented, and the construction quality is improved.
本发明公开了一种公路桥梁抗压路基，包括土基层、混凝土层、稳定层、加强层、土工布层、防水土工膜层和面层，所述土基层位于所述混凝土层的下方，所述混凝土层位于所述稳定层的下方，所述稳定层位于所述加强层的下方，所述加腔层位于所述土工布层的下方，所述土工布层位于所述防水土工膜层的下方，所述防水土工膜层位于所述面层的下方；所述土基层按重量份数计包括：石灰20‑30份、煤灰15‑20份、粘土20‑25份、灰土30‑50份和沙砾1‑3份。本发明提高了路基整体抗压抗震性，防止微裂纹的产生，提高了施工质量。
