钢渣SMA-13在武黄大修工程中的应用研究

Application Study of Steel Slag SMA-13 in Wuhuang Highway Heavy-repairing Project

依托武黄高速公路大修改造工程 ,采用破碎钢渣以及 SBS改性沥青 ( PG76 - 2 2 )等作为原材料 ,进行钢渣沥青混凝土的应用研究 ,设计出 SMA- 13型沥青混合料的配合比 ,并在武黄高速公路豹段匝道处进行了钢渣 SMA- 13试验段的铺筑。后期检测试验结果表明试验段各项性能指标较好。

Based on Wuhuang highway heavy repairing project,steel slag SMA 13 asphalt mixture was designed using crushed steel slag and SBS modified asphalt PG 76 22 as raw materials.Meanwhile,steel slag asphalt mixture was paved at entrance and exit of Baoxie,Wuhuang highway and the results of examination were satisfied.
