摘　　要：建筑垃圾再生料作为新型环保、可循环利用材料,已经受到了广泛的关注。若能将其应用在道路工程中,不仅可以减少对砂石的开采,节约资源,还能降低工程的成本。这对中国公路建设的发展具有重要意义。然而由于建筑垃圾再生料相对天然骨料而言有着强度低、吸水率高等缺点。因此,建筑垃圾再生料路基与传统路基相比会存在明显的差异。将根据现有的研究成果,对建筑垃圾再生料在路基填筑时的基本性能、路用性能以及沉降变性特性进行阐述。最后分析并展望了未来的研究方向,有助推动建筑垃圾再生料在路基工程的应用。As a new environmentally friendly and recyclable material,recycling construction and demolition waste(CDW)have received extensive attention.If it can be applied in road engineering,it will not only reduce the exploitation of sand and stone,save resources,but also reduce the cost of the project.This is of great significance to the development of highway construction in China.However,compared with natural aggregate,CDW has the disadvantages of low strength and high water absorption.Therefore,there are obvious differences between the CDW subgrade and the traditional subgrade.Based on the existing research results,the basic performance,road performance and settlement degeneration characteristics of CDW in subgrade filling are expounded.Finally,the future research directions are analyzed and prospected,which is helpful to promote the application of construction waste recycling materials in subgrade engineering.
