Full-granularity steel slag pavement base material for heavy-duty pavement
The invention discloses a full-granularity steel slag pavement base material for a heavy-load pavement The full-granularity steel slag pavement base material is prepared by adding water into a dry material and uniformly mixing, and the dry material comprises 3.4-5.0% of a cementing material and 95.0-96.6% of steel slag aggregate; the cementing material is prepared by mixing 70-90% by mass of cement and 10-30% by mass of steel slag micro-powder according to a certain ratio; and the water accounts for 5-6% of the total mass of the dry material. Excellent physical properties and potential gellingactivity of the steel slag are utilized, the base material with high strength, small cement dosage and reduced dryness can be prepared without additives, the base material is suitable for the heavy-load pavement, and the service life of the heavy-load pavement is prolonged; and an application of the full-granularity steel slag in the base material is realized, natural resources are effectively saved, the problems of environmental pollution and the like caused by improper treatment of the steel slag are reduced, the production cost is reduced, and remarkable social, economic and environmentalbenefits are achieved.
本发明公开了一种用于重载路面的全粒度钢渣路面基层材料，由干料加水均匀拌合制备而成，所述干料包括胶结料、钢渣集料；其中胶结料、钢渣集料总质量的百分数为：胶结料3.4％～5.0％、钢渣集料95.0％～96.6％；所述胶结料为水泥与钢渣微粉按一定比例混合制备而成，水泥与钢渣微粉的质量百分数为：水泥70％～90％、钢渣微粉10％～30％；水占干料总质量的5％～6％。本发明所述基层材料利用了钢渣优异的物理特性和潜在胶凝活性，无需外加剂，便可制备得到强度高、水泥用量小、干缩小的基层材料，适用于重载路面中，延长重载路面的服役寿命；而且实现了全粒径钢渣在基层材料中的应用，有效节约了天然资源，减少了钢渣处理不当导致的环境污染等问题，降低了生产成本，具有显著的社会经济环境效益。
