Environment-friendly semi-rigid base layer for road engineering
The invention relates to the technical field of road engineering, and particularly discloses an environment-friendly semi-rigid base for road engineering, and the semi-rigid base material comprises the following components in parts by mass: 1000 parts of waste inorganic matters, 0.6-1.0 part of a soil stabilizer and 50-60 parts of purified water; the waste inorganic matter comprises at least one of soil, construction waste residues or clay, and the proportion of raw materials with the particle size larger than 10 mm in the waste inorganic matter is not smaller than 40%; the soil stabilizer is prepared from the following components in parts by mass: 42 to 48 parts of chlorine salt, 14 to 20 parts of phosphate, 52 to 58 parts of sulfate, 90 to 94 parts of metal hydroxide, 4 to 8 parts of carbonate, 95 to 105 parts of water-based resin, 1 to 3 parts of triethanolamine, 22 to 28 parts of silicon dioxide and 1 to 3 parts of catalyst. The raw materials of the semi-rigid base layer material are selected according to the proportion and then stirred evenly, then paving and rolling are conducted to complete base layer construction, and surface layer construction is conducted 24 h after base layer construction is completed; and the problems of high base construction cost, low strength and long maintenance time in road engineering are solved.
本发明涉及道路工程技术领域，具体公开了一种道路工程用环保半刚性基层，半刚性基层材料中各组分的质量份数为1000份的废弃无机物、0.6～1.0份的土壤固化剂、50～60份的纯净水；废弃无机物包含泥土、建筑垃圾废渣或黏土中的至少一种，废弃无机物中粒径＞10mm的原料占比不小于40％；土壤固化剂中各组分的质量份数为氯盐42～48份，磷酸盐14～20份，硫酸盐52～58份，金属氢氧化物90～94份，碳酸盐4～8份，水性树脂95～105份，三乙醇胺1～3份，二氧化硅22～28份，催化剂1～3份；半刚性基层材料按照上述配比选取原料后搅拌均匀，再摊铺、碾压完成基层的施工，基层施工完24h进行面层施工；解决了道路工程中基层施工成本高，强度低以及养护耗时长的问题。
