Highway base mixture and low-carbon construction method
The invention discloses a road base mixture and a low-carbon construction method. The road base mixture comprises gravel aggregate and a pre-excitation composite cementing material, and the pre-excitation composite cementing material comprises a hydraulic cementing material, mineral powder, gypsum powder, fly ash and an exciting agent which are mixed and ground. And one-step full-thickness construction can be realized by using the base mixture. A large amount of superfine slag powder and fly ash are used in the pre-excited composite cementing material to replace cement components in the existing cementing material, so that the highway construction cost and the construction and maintenance cost are greatly reduced, and low-carbon emission and consumption of highway engineering can be realized. And the pre-excited composite cementing material is subjected to secondary activation, so that the activity of the slag can be comprehensively exerted, and the early strength and the base bearing capacity are favorably improved. The surface is covered with an oil permeable layer after paving, maintenance is not needed, the construction period is shortened, and the maintenance cost is reduced. The integrally formed roadbed is high in shear resistance, small in expansibility, compact in structure and free of rotten roots at the bottom.
本发明公开了一种公路基层混合料及低碳施工方法，包括碎石骨料、预激复合胶结料，预激复合胶结料包括混合研磨的水硬性胶凝材料、矿粉、石膏粉和粉煤灰和激发剂。利用基层混合料可实现一步法全厚度施工。预激复合胶结料中大量使用矿渣微粉以及粉煤灰，替代现有胶结料中的水泥组分，公路造价成本，施工养护成本都大幅降低，能够实现公路工程的低碳排放和消耗。预激复合胶结料经过二次激活，矿渣活性能够得到全面的发挥，有利提高早期强度和基层承载能力。一步法全厚度施工，摊铺后其表面覆盖有透油层，无需养护，节省工期和养护成本。整体成形的路基抗剪切能力强，膨胀性小，结构密实，底部无烂根。
