High-performance paving cushion material and preparation method thereof
The invention relates to a high-performance paving cushion material and a preparation method thereof, according to a formula, a cement base material, an active mixed material, coarse aggregate, quartz sand, an alkali activator and water are uniformly stirred to obtain the high-performance paving cushion material, wherein the cement base material comprises at least one of sulphoaluminate cement, Portland cement or anhydrite. Compared with the prior art, a sulphoaluminate cement-Portland cement-gypsum ternary system is used for replacing part of Portland cement, and the problems that a pavement cushion layer is low in early strength and prone to loosening are solved. And moreover, more solid waste materials are used, so that green and energy-saving effects are effectively realized, and resources are efficiently recycled.
本发明涉及一种高性能铺路垫层材料及其制备方法，按配方，将水泥基料、活性混合材、粗骨料、石英砂、碱激发剂和水搅拌均匀，得到高性能铺路垫层材料；其中，水泥基料包括硫铝酸盐水泥、硅酸盐水泥或无水石膏中的至少一种。与现有技术相比，本发明使用硫铝酸盐水泥‑硅酸盐水泥‑石膏三元体系替代部分硅酸盐水泥，改善了路面垫层早期强度较低，易松动的问题。并且本发明使用较多固废材料，有效实现绿色节能、资源高效回收利用。
