摘要
随着建筑业的快速发展,由建筑业产生的建筑垃圾也在逐年增加。建筑垃圾除处理费用相当惊人外,还会带来严重的环境问题和不良的社会影响。本文主要以建筑垃圾为研究对象,将其作为再生骨料与土掺和做路面基层材料为研究目的。先分析建筑垃圾的组成成分和物理性质;其次研究土的最佳含水率和最大干容重;最后根据设计的再生骨料和土的配合比制作试件,按照标准条件养生,测定7d和28d的无侧限抗压强度。通过试验得到的结论为无侧限抗压强度在养生7d后达到了二级及二级以下公路底基层的强度要求,养生28d后达到高速公路及一级公路底基层和二级及二级以下公路基层的要求。
With the quick development of the building industry,construction waste from building industry is also increasing year by year.Besides the handling charge of construction waste is staggering,it also brings about serious environmental problems and bad social affect.This article mainly focused on the way which the pavement grass-roots material is made from the recycled aggregates of construction waste mixed with the soil.Firstly,the composition of construction waste and the physical characters were analyzed.Secondly,the optimum moisture content and maximum dry density of the soil were studied.Finally,the specimen were made according to the mixture ratio of the recycled aggregate and the soil,specimen were cured under standard condition,unconfined compressive strength were measured after curing 7 days and 28 day.The results showed that the unconfined compressive strength cured 7 days met the under base curse requirements of second grade or under second grade road,and the unconfined compressive strength cured 28 days met the under base curse requirement of expressway or base curse requirement of the second grade or under second grade road.
