Anti-cracking building solid waste road flexible base mixture and preparation method thereof
The invention relates to an anti-cracking building solid waste road flexible base mixture and a preparation method thereof. The base mixture comprises building solid waste mixed aggregate, asphalt and mineral powder, the building solid waste mixed aggregate is composed of crushed concrete aggregate, crushed tiles, crushed ceramics and crushed glass, and the mass ratio of the crushed concrete aggregate to the crushed ceramics to the crushed glass in the coarse aggregate of the building solid waste mixed aggregate is (68-74): (23-29): (0.1-0.6); the asphalt is any one or a combination of heavy traffic 70 # matrix asphalt or 90 # matrix asphalt; the mineral powder is limestone mineral powder with the purity of 90%-100% and the particle pitch diameter of 0.8 mu m-12 mu m. On one hand, cracks generated by temperature shrinkage and dry shrinkage of the road base can be reduced, and the phenomenon that reflection cracks appear on a surface layer due to base cracking is effectively prevented; on the other hand, the building solid waste is applied to the road base, so that the material cost is reduced, natural mineral resources are saved, the ecology can be protected, the problems of environmental pollution and the like can be solved, and obvious environmental benefits, economic benefits and social benefits are achieved.
本发明涉及一种抗开裂的建筑固废道路柔性基层混合料及其制备方法，基层混合料包括建筑固废混合骨料，沥青，矿粉；建筑固废混合骨料由破碎混凝土骨料、破碎砖瓦、破碎陶瓷、破碎玻璃组成，建筑固废混合骨料的粗骨料中破碎混凝土骨料、破碎陶瓷、破碎玻璃的质量比例为(68‑74):(23‑29):(0.1‑0.6)；沥青为重交70#基质沥青或90#基质沥青任意一种或其组合；矿粉为纯度为90％‑100％、颗粒中径为0.8um‑12um的石灰石矿粉。本发明一方面能够降低道路基层因温缩和干缩产生的裂缝，有效防止基层开裂导致面层出现反射裂缝的现象；另一方面将建筑固废应用到道路基层中，不仅降低了材料成本、节省天然矿产资源，还能够保护生态，解决环境污染等问题，具有明显的环境效益、经济效益和社会效益。
