摘　　要：建筑垃圾处理后资源化利用,可以减少对环境的破坏,同时大量减少了新材料的用量,为当今循环经济和绿色发展开辟了一条新道路;但在建筑垃圾再生利用过程中还存在很多的问题有待进一步研究解决。针对建筑垃圾在路床填筑中再生利用进行研究,从购买的建筑垃圾再生料的基本指标检测入手,在到填筑的不同含石量最佳含水率测试,最后利用无损的动态变形模量测定仪(Evd)进行路床填筑性能测试。由动态变形模量测定的不同龄期下测试结果进行分析,得出建筑垃圾再生料填筑的路基床有随龄期增加不断增大的结果。After the treatment of construction waste,the utilization of resources can reduce the damage to the environment,and greatly reduce the consumption of new materials,which opens up a new road for today s circular economy and green development.However,there are still many problems to be solved in the process of construction waste recycling.The recycling of construction waste in roadbed filling was studied,starting from the basic index test of the purchased construction waste recycling materials,then to the best moisture content test of different stone content,and finally using the non-destructive dynamic deformation modulus tester(Evd)to test the roadbed filling performance.Based on the analysis of the test results of different ages measured by dynamic deformation modulus,it is concluded that the roadbed filled with construction waste recycled material is increasing with the age.
