| 摘 要： | 首先选用多种分析方法对钢渣微粉的化学成分、相成分和微观形貌等进行分析;然后在沥青混合料中掺加钢渣微粉,研究用钢渣微粉部分或全部替代矿粉对沥青混合料性能的影响。结果表明:掺加钢渣微粉明显提高沥青混合料的水稳定性和高温稳定性,而对沥青混合料的抗裂性影响不大;钢渣微粉的适宜掺量为沥青混合料总质量的4.5%。

| Abstract: | The chemical components,phase components,and micro-structure properties of steel slag powder are analyzed. Then steel slag powder is added into the asphalt mixture,and the effect of partial or total replacement of mineral powder with steel slag powder on performance of asphalt mixture is studied.The test results indicate that water stability and high-temper- ature stability of asphalt mixture can be improved markedly when the steel slag powder is used instead of mineral powder. And the influence of the steel slag powder addition on the anti-clacking performance of asphalt mixture isn' t remarkable. The optimum dosage of steel slag powder in asphalt mixture is 4.5% of the total quality. |
