Abstract
为了明确建筑废弃物应用于路基填料的使用性能,通过系统的室内试验,研究建筑垃圾再生骨料的基本性能,通过标准击实试验以及承载比试验,得出混合料的最大干密度、最佳含水量以及CBR值,分析了建筑废弃物混合料不同砖混凝土比例以及在土中的不同掺量对以上指标的影响,得出了建筑废弃物混合料用于路基填料中的最佳配比.经试验和模拟分析,各配比混合料下的CBR值均能满足现行规范的要求,可以在道路工程中使用.
In order to investigate the service performance of construction waste applied to subgrade filling material,through systematic tests,the basic properties of recycled aggregate of construction waste was researched;the maximum dry density,the optimum water content and the CBR value of the mixture were obtained by the standard compaction test and the bearing ratio test.The influence of different proportion of brick concrete and its content in soil on the above indexes were analyzed,and the best proportion of the construction waste mixture in roadbed fillings was obtained.Through the experiment and simulation analysis,the CBR value of the mixture can meet the requirements of the current code,and can be used in the road engineering.
