转炉钢渣做集料在SMA-13中的应用研究

The Study on Application of Converter Steel Slag as Aggregate in SMA-13

在国外,钢渣作为筑路材料被广泛应用在路面工程中,针对太钢转炉钢渣的性能特点,对钢渣进行性能分析,研究其材料特性,设计钢渣沥青混合料,通过比对测定转炉钢渣沥青混合料的高温稳定性、低温抗弯性和水稳定性,结果表明钢渣可在SMA-13中做集料使用。

Taken as the road material, the steel slag has been widely used in the pavement engineering abroad. This paper conducted performance analysis on steel slag, studied its material characteristics and designed steel slag asphalt mixture based on the performance features of converter steel slag from Taiyuan Iron Steel Co.,Ltd. The results showed that the steel slag could be used as the high-quality aggregate in SMA-13 through comparing and testing the high-temperature stability, low-temperature bending resistance and water stability of converter steel slag asphalt mixture.
