建筑垃圾减量化、资源化综合利用的路基填筑技术应用研究

Research on the Application of Subgrade Filling Technology of Construction Waste Reduction and Comprehensive Utilization of Resources

本文以“双碳”背景下的绿色交通体系构建为应用基础,针对建筑垃圾的与日俱增与新建路基工程土资源匮乏的不平衡现象,提出将建筑垃圾减量化、资源化综合利用技术应用于路基填筑,在综合分析建筑垃圾再生骨料组分、不均匀性和吸水率等研究的基础上,进行高液限土建筑垃圾改良效果研究,推荐不同公路等级和交通荷载等级路基适用的建筑垃圾骨料掺量、钻渣掺量和固化剂掺量的科学配比,有效解决路基修建过程中土方匮乏问题,保护了耕地资源,同时,以建筑垃圾减量化、资源化的综合利用,推动中国建造低碳转型,助力国家“双碳”目标实现。

Based on the construction of green transportation system under the background of double carbon,this paper proposes the application of construction waste reduction and resource comprehensive utilization technology to roadbed filling in view of the imbalance between the increasing construction waste and the lack of soil source in the new roadbed project.Based on the comprehensive analysis of the research on the composition of recycled aggregate of construction waste,non-uniformity and water absorption,etc.,research on the improvement effect of construction waste with high liquid limit soil,recommend the scientific ratio of construction waste aggregate content,drilling slag content and curing agent content applicable to roadbed of different highway levels and traffic load levels,effectively solve the problem of lack of earthwork during roadbed construction,protect the area of cultivated land resources,and at the same time,comprehensively utilize construction waste reduction and resource utilization,which promote the low-carbon transformation of China's construction,and help the implementation of the national"dual carbon"target.
