Advances in Constructional Engineering

As urbanization accelerates, the volume of construction waste has surged dramatically. How to achieve efficient resource utilization of this waste has become a crucial issue for environmental protection and sustainable development. Road subbase, as an essential part of infrastructure, holds significant potential for use. This paper focuses on the application of construction waste in road subbases, analyzing its physical and mechanical properties as well as environmental impacts. It explores reasonable processing and mixing techniques to ensure safe, economical, and environmentally friendly utilization of construction waste, promoting green development in road construction. The study shows that the rational use of construction waste not only reduces construction costs but also effectively minimizes the negative environmental impact of waste disposal, making it widely valuable for promotion.
