Inverted roadbed and pavement structure for comprehensively utilizing solid wastes
The invention discloses an inverted roadbed and pavement structure capable of comprehensively utilizing solid wastes. Comprising an upper embankment, a roadbed, a pavement subbase layer and a pavement upper base layer, wherein the upper embankment, the roadbed, the pavement subbase layer and the pavement upper base layer are paved in sequence; the upper embankment is filled with demolition and construction solid waste recycled aggregate; the roadbed is paved by cement-desulfurized slag-gypsum composite stable engineering muck; the pavement lower surface layer and the pavement middle surface layer are paved by the hot mix plant recycled SBS modified asphalt mixture, the upper surface layer is paved by the semi-flexible pavement material, and the asphalt wearing layer is paved by the high-viscosity modified asphalt mixture. Optimized combination design is carried out according to the stress characteristics and functional characteristics of all the structural layers, and the structure can be used for high-grade roads and has the advantages of being long in service life, high in driving safety and comfort and the like; the material selection of each structural layer accords with the green ecological development concept under the background of double carbon, and the reasonable utilization of bulk solid wastes in the field of road engineering is realized.
本发明公开了一种固体废弃物综合利用倒装式路基路面结构，包括依次铺装的拆建固体废弃物再生集料填筑的上路堤、由水泥‑脱硫矿渣‑石膏复合稳定工程渣土铺筑的路床、由脱硫石膏‑水泥稳定拆建固体废弃物再生集料铺筑的路面底基层、由废旧混凝土再生骨料级配碎石铺筑的路面上基层、由厂拌热再生SBS改性沥青混合料铺筑的路面下面层和中面层、由半柔性路面材料铺筑的上面层、由高粘度改性沥青混合料铺筑的沥青磨耗层。本发明根据各结构层受力特性与功能特点进行优化组合设计，可用于高等级道路，具有使用寿命长、行驶安全性和舒适性高等特点；各结构层选材符合“双碳”背景下绿色生态发展理念，实现了道路工程领域大宗固体废弃物的合理利用。
