摘要
为探索煤矸石填筑路基的合理碾压方式,以青兰高速邯涉段工程为依托,采取煤矸石路基填筑冲击压实与普通振动压实后冲击增强补压两种碾压方式铺筑试验路,分别采用灌砂法和沉降法对不同试验段压实度进行对比检测,同时对碾压前后的煤矸石进行取样筛分试验和压碎值试验,最后分析了不同压实方式对煤矸石路基的压实度、级配及压碎值的影响效果.
To explore reasonable rolling way for coal gangue as subgrade filling materials,based on project of Handan-She County segment within Qinglan Express,two kinds of rolling ways which are impact compaction and ordinary vibrating compaction followed with impact enhancing compaction are applied on to pave test road.Then,sand replacement method and sedimentation method are comparatively selected to measure compactness on every test sections.Meanwhile,sample screening test and crushing value test are applied on co...
