摘　　要：研究了桥面铺装下层的制备新工艺,以铁尾矿、炉渣为主要新原料,普通硅酸盐水泥为胶凝剂,钢纤维为掺合料,制备出轻质高强、隔热保温的桥面铺装下层混凝土。试验研究表明:新型混凝土的有关性能均达到交通部规定标准,隔热保温性能明显优于普通混凝土及沥青混凝土,可以解决大跨度桥梁温度突变病害,并为综合利用铁尾矿和炉渣提供了一条新的技术途径。The new technique in fabrication of bedding deck pavement,using iron tailling,slag as new ingredients,common pottland cement as gelling agent,and steel fibre as additive to produce bedding deck pavement concrete with light weight,excellent toughness and heat insulation was studied.All the performances of the new concrete are up to the standards set by the Ministry of Communications.As well,the heat insulation is ob-viously better than that of the common concrete and asphalt concrete,so it can cure the diseases caused by sudden changes in demperature in big span bridges and provide a new technical way to utilize iron tailling and slag comprehensively.
