摘要
随着我国经济的迅猛增长,基础设施日益健全,工业化进程在为人们生活带来诸多便捷的同时,也催生了大量固体废弃物的产生。这些废弃物的堆放不仅侵占了宝贵的土地资源,而且引发了严重的环境污染问题,使得废弃物的妥善处理成为一个亟待解决的重大课题。随着道路建设总里程的持续增加,道路路基施工对砂石材料的需求日益增大,而将固体废弃物应用于道路路基建设,成为一种有效的废弃物处理方式。此外,部分固体废弃物在半刚性基层中的应用展现出了卓越的性能,如粉煤灰和钢渣等,其凭借自身或经活化后展现出的化学活性,能够在结构中生成足够的强度,满足工程施工的严格要求,同时探讨了固废在半刚性基层中的应用。
With the rapid growth of China s economy and the increasingly sound infrastructure,the process of industrialization has brought us a lot of convenience in life,but also given rise to a large number of solid waste generation.These waste piles not only encroach on valuable land resources,but also caused serious environmental pollution problems,making the proper disposal of waste has become a major issue that needs to be resolved.As the total mileage of road construction continues to increase,the demand for sand and gravel materials for roadbed construction is increasing,and the application of solid waste to roadbed construction has become an effective way of waste disposal.In addition,the application of some solid wastes in semi-rigid subgrade shows excellent performance,such as fly ash and steel slag,etc.,which,by virtue of their own or activated chemical activity,can generate sufficient strength in the structure to meet the strict requirements of engineering construction.The application of solid waste in semi-rigid base layers is also explored.
