Bituminous pavement structure fully using iron tailings and construction method of bituminous pavement structure
The invention discloses an asphalt pavement structure using iron tailings in the whole structure and a construction method thereof, and aims to realize resource utilization of road construction materials, improve the road performance and reduce the environmental influence at the same time. The structure comprises a roadbed layer, a pavement base layer and a surface layer from bottom to top, and is completely or partially made of iron tailing materials. The roadbed layer is completely made of lime-stabilized iron tailing soil instead of traditional lime-stabilized soil; the pavement base layer is formed by replacing fine aggregate in equal-particle-size water-stable gravel with iron tailings; and the asphalt surface layer adopts iron tailings to partially replace mineral powder in the asphalt mixture. The iron tailing particles have specific particle size distribution, plasticity index and organic matter content, and have specific proportions of iron, silicon, calcium, aluminum and other elements. In addition, the invention further comprises thickness value ranges corresponding to all layers of urban roads of different grades, preparation of iron tailing mixtures and the like. The invention provides an environment-friendly, economic and high-performance novel road structure and a construction method for urban asphalt roads, and has a wide application prospect.
一种全结构使用铁尾矿的沥青路面结构及其施工方法，旨在实现道路建设材料的资源化利用，提升道路性能的同时降低环境影响。该结构从下到上包括路基层、路面基层和面层，全部或部分由铁尾矿材料构成。路基层完全由石灰稳定铁尾矿土替代传统石灰稳定土；路面基层由铁尾矿替换等粒径水稳碎石中的细集料；沥青面层采用铁尾矿部分替代沥青混合料中的矿粉。铁尾矿颗粒具有特定的粒径分布、塑性指数和有机质含量，以及铁、硅、钙、铝等元素的特定比例。此外，本发明还包括不同等级城市道路各层位对应的厚度取值范围、铁尾矿混合料的制备等。本发明为城市沥青道路提供了一种环保、经济且高性能的新型道路结构和施工方法，具有广泛的应用前景。
