摘　　要：针对煤矸石自身特点,以依七高速公路路基填筑煤矸石为例,在研究七台河几种矿区煤矸石材料路用性能基础上,确定了本工程高速公路路用煤矸石各项性能指标要求,结合依七高速公路路基现场试验路铺筑,提出了高速公路路基填筑压实煤矸石施工工艺以及施工质量控制方法。结果表明:煤矸石作为路基填筑材料具有压缩性小、稳定性好的特点,在矿区城市将其作为公路路基填筑材料具有很好的推广应用价值。According to the characteristics of coal gangue itself,in accordance with the seven highw-ay roadbed filling gangue,for example,Based on the research road gangue raw materials is,determine the road with coal gangue various performance indicators,Combined with field test road paving,and puts forward the highway roadbed filling gangue construction technology and construction quality control method.The results showed that:Coal gangue as subgrade filling material have the characteristics of small compressibility,good stability,In the mining city as a highway roadbed filling material has good popularization and application value.
