Granite residual soil roadbed structure and construction method thereof
The invention discloses a granite residual soil roadbed structure and a construction method thereof, and belongs to the technical field of environmental protection. Comprising a bottom isolation layer, a granite residual soil filling area, geocell protection areas, a strength compensation layer and a pavement structure layer, the bottom isolation layer is arranged at the bottom of the granite residual soil filling area, and the geocell protection areas are arranged on the two sides of the granite residual soil filling area respectively. The geocell protection area comprises a left geocell protection slope and a right geocell protection slope, the top of the granite residual soil filling area is a strength compensation layer and a pavement structure layer, a subbase layer and a base layer of the pavement structure layer are cement stabilized macadam layers, and the subbase layer and the base layer are of a whole-width full-paving type structure. And a closed central separation strip is arranged on the pavement structure layer. According to the method, rainfall runoff is effectively prevented from eroding the granite residual soil side slope, water is prevented from permeating into the granite residual soil roadbed, the humidity stability of a granite residual soil filling area is guaranteed, the long-term performance stability of the granite residual soil roadbed is guaranteed, construction is more convenient, and the manufacturing cost is low.
一种花岗岩残积土路基结构及其施工方法，属于环保技术领域。包括底部隔离层，花岗岩残积土填筑区，土工格室防护区，强度补偿层和路面结构层五个部分，花岗岩残积土填筑区的底部为底部隔离层，花岗岩残积土填筑区的两侧分别为土工格室防护区，土工格室防护区包括左土工格室护坡及右土工格室护坡，花岗岩残积土填筑区的顶部为强度补偿层及路面结构层，路面结构层的底基层和基层为水泥稳定碎石层，底基层和基层为整幅全铺式结构。路面结构层上有封闭式中央分隔带。本发明有效避免降雨径流冲蚀花岗岩残积土边坡，避免水分入渗花岗岩残积土路基，保证花岗岩残积土填筑区的湿度稳定，保障花岗岩残积土路基的长期性能稳定，施工更加方便，造价低廉。
