摘要
以福州绕城高速公路福州北互通内拆迁产生的建筑渣土为实例,对建筑渣土的颗粒组成、级配特征及组分特性等展开研究.并进行了填筑路基试验段的现场测试,探索了建筑渣土的振动压实特性,给出了路基利用建筑渣土填筑的合理松铺厚度和碾压遍数等参数.
Describes the research on the particle composition,particle size distribution and components properties of the construction wastes,taking the construction wastes utilized in the Surround Urban Freeway in Fuzhou as the case study. To evaluate the compaction property by vibrating,a field test was conducted in a subgrade test section. Then,some key parameters utilizing construction wastes as the subgrade filler,such as the reasonable thickness of uncompacted layer and the number of roller passes,are provided. The research is valuable for further studies on the properties of construction wastes utilized as subgrade filler.
