钢渣在沥青路面面层中的应用研究

Application on Steel Slag in Surface Course of Asphalt Pavement

近年来,由于公路建设的飞速发展,导致优质的筑路资源紧缺,而钢渣作为一种产量巨大的工业废弃物,其物理力学性质和天然石料类似,若是可以推广应用于道路工程,则会产生巨大的价值。基于此,本文对钢渣的材料组成和基本性质进行了详细的总结,又经过调研分析,综述了近年来钢渣在国内外沥青路面面层中的研究进展和应用现状。研究发现,钢渣沥青混凝土路面的路用性能良好,满足规范要求,钢渣只要经过适当的处理,完全可以广泛应用于沥青路面。但是钢渣在当前的应用环境和技术条件下还普遍存在一些问题,对此,本文最后指明了钢渣未来的发展方向。…

In recent years, due to the rapid development of highway construction, high quality road resources are scarce. The steel slag as an industrial waste of great yield, the physical and mechanical properties are similar to natural stone. If it can be applied to road engineering, it will produce great value. Based on this, the material composition and basic properties of steel slag are summarized in detail, after further investigation and analysis, the research progress and application of steel slag in surface course of asphalt pavement at home and abroad are reviewed. It is found that the steel slag asphalt concrete pavement has good road performance and meets the requirements of the specifications. As long as the steel slag is properly treated, it can be widely used in asphalt pavement. However, there are still some problems in the current application environment and technical conditions of steel slag. In this regard, the future development direction of steel slag is pointed out in this paper.
