Solid-waste-based alkali-activated cementing road building material, preparation method and road building method
The invention discloses a solid-waste-based alkali-activated cementing road building material, a preparation method and a road building method. The road building material comprises 45-68 parts of slag; 23 parts of fly ash; 382 parts of an original road clay-bound macadam material; and 40-55 parts of water glass. The preparation method comprises the following steps: uniformly mixing sodium silicate, sodium hydroxide and water to prepare a water glass exciting agent with the water content of 75% and the modulus of 1.5; 23 parts of fly ash, 45 parts of slag, 382 parts of an original road clay-bound macadam material and 55 parts of the water glass exciting agent are sequentially put into a stirring machine to be uniformly stirred, and the road building material is obtained. The road building method comprises the following steps: uniformly paving the fly ash and the slag on an original road surface by adopting a powder paver; milling the original soil hardened pavement by adopting a cold regeneration machine; injecting an exciting agent, and fully mixing the exciting agent with the solid mixed material; adopting a road roller and a road grader for repeatedly rolling and scraping the road surface; the material and the preparation method are low in manufacturing cost and good in environmental protection performance; the method is simple in process and high in road building efficiency.
一种固废基碱激发胶凝筑路材料、制备方法及筑路方法，筑路材料：矿渣45～68份；粉煤灰23份；原道路泥结碎石材料382份；水玻璃40～55份。制备方法：将硅酸钠、氢氧化钠、水均匀混合制成含水率75％、模数为1.5的水玻璃激发剂；将粉煤灰23份、矿渣45份、原道路泥结碎石材料382份以及所述的水玻璃激发剂55份依次放入搅拌机中进行均匀搅拌得到筑路材料。筑路方法：采用粉料摊铺机将粉煤灰和矿渣均匀摊铺在原道路路面上；采用冷再生机对原有土质硬化路面进行刨铣；喷注激发剂，使激发剂与固体混合材料充分混合；采用压路机、平路机对路面进行反复碾压与刮平；该材料及制备方法制造成本低、环保性能好；该方法工艺简单，筑路效率高。
