Lime mineral powder stabilized steel slag pavement base mixture and preparation method thereof
The invention belongs to the technical field of road engineering, and discloses a lime mineral powder stabilized steel slag pavement base mixture and a preparation method thereof. The lime mineral powder stabilized steel slag pavement base mixture is prepared from the following raw materials in percentage by weight: 4-9% of cementing material and 91-96% of steel slag aggregate, wherein the cementing material is prepared from the following raw materials in percentage by weight: 17-25% of lime and 75-83% of slag powder. The 7d unconfined compressive strength of the steel slag-based pavement base mixture prepared under the condition that Portland cement is not added is remarkably improved through optimal design of the mass ratio of the lime to the mineral powder to the steel slag.
本发明属于道路工程技术领域，公开了一种石灰矿粉稳定钢渣路面基层混合料及其制备方法。本发明中石灰矿粉稳定钢渣路面基层混合料，由包含以下百分含量的原料制备而成：胶凝材料4～9％，钢渣集料91～96％；其中，胶凝材料由包含以下百分含量的原料制备而成：石灰17～25％，矿渣粉75～83％。通过对石灰、矿粉和钢渣的质量配比优化设计，使在不加入硅酸盐水泥的条件下所制备的钢渣基路面基层混合料7d无侧限抗压强度显著提升。
