| Abstract: | 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... |
