Highway carbonaceous soft rock high-performance roadbed structure and construction method thereof
The invention discloses an expressway carbonaceous soft rock high-performance roadbed structure and a construction method thereof, and relates to the technical field of road construction, the expressway carbonaceous soft rock high-performance roadbed structure comprises an isolation layer, a carbonaceous soft rock filling area, an upper embankment, a roadbed and a pavement which are sequentially arranged from bottom to top; anti-seepage areas are arranged on the two sides of the carbonaceous soft rock filling area, and anti-seepage layers distributed in sequence are arranged in the anti-seepage areas; a groove is formed in the road surface, a sleeper beam is arranged in the groove, two sets of New Jersey guardrails are arranged above the sleeper beam, and a concrete cushion layer, a sand filling layer and a planting soil layer are clamped in the two New Jersey guardrails from bottom to top. By means of the arrangement, the carbonaceous soft rock excavated along the line can be fully utilized as roadbed filler, the reinforcement and waterproof effects of the geogrid and the composite geotextile, the waterproof effect of the isolation layer at the bottom of the embankment and the water sealing effect of the separation type New Jersey guardrail of the medial strip are fully utilized, and the stability of a roadbed humidity field is jointly ensured; further, the engineering property of the carbonaceous soft rock filler is kept stable.
本发明公开了一种高速公路炭质软岩高性能路基结构及其施工方法，涉及道路施工技术领域，包括自下而上依次设置的隔离层、炭质软岩填筑区、上路堤、路床和路面；炭质软岩填筑区两侧设置有防渗区，防渗区内设置有依次分布的防渗层；路面上开设有凹槽，凹槽内设置有枕梁，枕梁上方设置有两组新泽西护栏，两新泽西护栏内夹设有自下而上的混凝土垫层、填砂层和种植土层。通过本发明的设置，既可充分利用沿线挖方的炭质软岩作为路基填料，又充分利用土工格栅与复合土工布的加筋和防水作用、路堤底部隔离层的隔水作用，以及中央分隔带分离式新泽西护栏的封水作用，共同确保路基湿度场的稳定，进而使炭质软岩填料的工程性质保持稳定。
