Magnesite waste rock and magnesite tailing semi-rigid pavement base material as well as preparation method and application thereof
The invention discloses a magnesite waste rock and magnesite tailing semi-rigid pavement base material as well as a preparation method and application thereof, and belongs to the technical field of solid waste resource utilization and inorganic binding stabilizing materials. Magnesite waste rock and magnesite tailings in grading design are used as aggregates of the pavement base material, and the particle size ranges of the magnesite waste rock and the magnesite tailings are 10-20 mm, 5-10 mm and 0-5 mm. The pavement base material prepared by taking the continuously-graded magnesite mining and stripping waste rocks and the magnesite tailings as the aggregates is good in anti-freezing property and strong in anti-scouring capability, and can meet the compressive strength requirements of second-grade and below road bases after being maintained for 7 days.
本发明公开了一种菱镁废石和菱镁尾矿半刚性路面基层材料及其制备方法和应用，属于固体废物资源化利用及无机结合稳定材料技术领域。以级配设计的菱镁废石和菱镁尾矿作为路面基层材料的集料，所述菱镁废石和菱镁尾矿的粒径区间为10‑20mm、5‑10mm和0‑5mm。本发明以连续级配的菱镁矿采剥废石和菱镁矿尾矿作为集料制备的路面基层材料抗冻性能好，抗冲刷性能力强，养护7d后即可满足二级及二级以下道路基层抗压强度要求。
