Semi-flexible pavement with good water permeability
The invention discloses a semi-flexible pavement with good water permeability. The semi-flexible pavement comprises a pervious concrete base layer, wherein the pervious concrete base layer is preparedfrom the following components in parts by mass: 6-8 parts of limestone fine aggregate; 5-10 parts of limestone mineral powder; 1 to 2 parts of triisopropanolamine; 35 to 45 parts of iron tailing sand; 2-3 parts of an expanding agent, 3 parts of lipase, 5 parts of sodium tripolyphosphate, 3 parts of butyl acrylate, 4 parts of alkyl glycoside, 4-9 parts of allyl methacrylate, 3-7 parts of starch ether, 20-30 parts of kaolin, 15-20 parts of sodium silicate, 6-8 parts of ferroferric oxide, 2-3 parts of zinc oxide, 3-5 parts of vegetable oil, 0.5-1 part of an antioxidant and 20-30 parts of water.The semi-flexible pavement adopts the pervious concrete base layer, so that the semi-flexible pavement has good durability and water permeability.
本发明公开了一种透水性好的半柔性路面，包括透水混凝土基层；其中，透水混凝土基层由如下质量份数的组分组成：6～8份石灰岩细集料、5～10份石灰岩矿粉、1～2份三异丙醇胺、35～45份铁尾矿砂、2～3份膨胀剂、3份脂肪酶、5份三聚磷酸钠、3份丙烯酸丁酯、4份烷基糖苷、4～9份甲基丙烯酸烯丙酯、3～7份淀粉醚、20～30份高岭土、15～20份硅酸钠、6～8份四氧化三铁、2～3份氧化锌、3～5份植物油、0.5～1份抗氧化剂以及水20～30份。本发明半柔性路面采用透水混凝土基层，使半柔性路面具有良好的耐久性和透水性。
