随着国家公路建设的蓬勃发展,在建公路对筑路材料的需求量迅猛增大,如何缓解这一矛盾,充分利用工业废渣代替碎石作为公路、城市道路的路面基层材料是一种较为科学有用的方法。目前,公路、城市道路的基层材料一般采用半刚性基层,如二灰碎石基层、水泥稳定碎石基层等,这些材料与工业废渣相比,材料费较高,道路的初期投入较大。按照当前基础建设的形势,如果能科学有效并且迅速的将高炉重矿渣应用于公路和城市道路中去,将会产生巨大的经济效益。高炉重矿渣属于工业废渣,大量的废渣堆积可能毁坏农
With the vigorous development of national highway construction, the demand for road construction materials on the roads under construction is rapidly increasing. How to alleviate this contradiction, and make full use of industrial waste instead of rubble as road and grassroots road materials for urban roads is a relatively scientific Useful method. At present, the grassroots materials of highways and urban roads generally use semi-rigid grassroots, such as lime-flyash gravel base and cement stabilized gravel base. These materials have higher material cost and higher initial investment in road than industrial waste. According to the current situation of infrastructure, if the scientific and effective and rapid application of blast-furnace slag on roads and urban roads, it will have enormous economic benefits. Blast furnace heavy slag belongs to industrial waste, a lot of waste accumulation may destroy agriculture
