摘要 为探究钢渣矿物成分对沥青混合料性能的影响,本研究采用不同种钢渣,分别按0%、30%、60%和100%的掺量及陈化前后30%的两种K钢渣进行沥青混合料的水稳定性测试,并采用XRD进行成分分析。研究结果表明:相比于普通石灰岩矿粉及水泥,不同钢渣的硅酸盐矿物及CaO等活性成分含量差异较大,且其对沥青混合料性能的提升存在较大差异。马歇尔稳定度及劈裂强度提升28.0%~40.0%;K钢渣随掺量增加,活性成分含量提高,对混合料性能提升也略有提高,马歇尔稳定度及劈裂强度提升38.0%~40.0%;钢渣陈化后活性矿物成分减少,对沥青混合料的提升效果减弱;水稳定性随活性成分增多有所降低;K钢渣在30%掺量时,水稳定性及劈裂强度性能提升最显著。 To explore the influence of steel slag mineral compositions on the performance of asphalt mixtures,this study conducted water stability tests on asphalt mixtures using different types of steel slag with 0%,30%,60%,and 100%blending ratios,as well as mixtures containing 30%K steel slag before and after aging,and conducted mineral composition analysis using XRD.The results showed that compared with ordinary limestone powder and cement,the content of silicate minerals and active minerals such as CaO in different types of steel slag varied greatly,and there were significant differences in the improvement of asphalt mixture performance with an increase in Marshall stability and splitting strength in the range of 28.0%to 40.0%.With the increasing amount of K steel slag,the content of active components increased,leading to improved performances of the asphalt mixture with an increase in the Marshall stability and splitting strength by 38.0%to 40.0%.After aging,the content of active minerals in steel slag decreased,and the improvement effect on the asphalt mixture weakened.Moreover,the water stability decreased with the increase of active components in the steel slag.The incorporation of 30%K steel slag resulted insignificant improvement in the water stability and splitting strength of the asphalt mixtures.
