Bearable geopolymer base water storage road
The invention provides a novel road concept, namely a bearable water storage road (a bearable geopolymer base water storage road), which is different from the current traditional sponge city mode. Theroad structure comprises a permeable asphalt layer, a permeable concrete layer, a geopolymer water storage layer and a cement concrete lower sealing layer from top to bottom. A cement concrete edge sealing layer is arranged on the edge of the road structure, and a drainage valve is arranged at the bottom of the cement concrete edge sealing layer. The gel material of the geopolymer water storage layer is geopolymer gel, and the aggregate is open-graded coarse aggregate; the geopolymer gel is prepared by mixing aluminum-silicon oxide (Si2O5 and Al2O2) and an alkali activator, and the molar ratio of elements to compounds in the gel is as follows: Si/Al = 1.8-2.5, Al/Na = 0.8-1.2, and H2O/Na2O = 13.5-17.0; the compressive strength of the geopolymer water storage layer meets the standards of expressways and first-grade roadbase layers; the water storage road can bear rainstorm (50mm/d-100mm/d) rainfall for 9-17 hours under the condition that a municipal drainage system is completely paralyzed.
本发明提出不同于目前传统海绵城市模式的新型道路概念——可承重的蓄水道路(可承重地聚合物基层蓄水道路)。道路结构包括从上到下的透水沥青层，透水混凝土层，地聚合物蓄水层，水泥混凝土下封层；在道路结构边部有水泥混凝土边封层，水泥混凝土边封层底部设置排水阀门。地聚合物蓄水层凝胶材料为地聚合物凝胶，骨料为开级配粗骨料；地聚合物凝胶由铝硅氧化物(Si2O5，Al2O2)和碱激发剂混合制备，凝胶中元素和化合物摩尔比为：Si/Al＝1.8～2.5，Al/Na＝0.8～1.2，H2O/Na2O＝13.5～17.0；地聚物蓄水层抗压强度满足高速公路、一级道路基层标准；蓄水道路能够在市政排水系统完全瘫痪的情况下，承受暴雨(50mm/d～100mm/d)9～17个小时的降雨量。
