【摘要】 针对大粒径再生碎石,根据散体材料桩对骨料各项要求进行了物理试验分析,对比天然碎石、混合碎石和再生碎石的微粉含量含泥量、表观密度、吸水率、压碎指标、最大干密度等,对大粒径再生碎石应用于散体材料桩的适应性进行了分析,试验成果对大粒径再生碎石拓展应用具有促进作用。更多还原

【Abstract】 According to the aggregate requirements of granular material pile,physical tests of large-grain diameter regeneration gravel were conducted. Powder content,mud content,apparent density,water absorption,crushing index,maximum dry density were measured and compared to natural gravel,mixed gravel and regeneration gravel,the inherent mechanism of experimental phenomena is discussed,the thesis make an adaptability analyze on that regeneration gravel was suitable as aggregate of granular material pile. This results of tests have a promoting value to expand applications of large-grain diameter regeneration grave.更多还原
