依托项目工程将掺钢渣混合料应用到路面面层与基层中，分别铺设SMA-13和AC-16钢渣沥青混合料面层试验段、水泥稳定钢渣碎石混合料和水泥粉煤灰稳定钢渣碎石混合料基层试验段，并对试验段检测指标进行研究和跟踪评价。结果表明，试验路段相关技术指标满足规范要求，运营过程中路面无明显病害，验证了掺钢渣混合料在路面面层与基层应用中的可靠性与可行性。

Based on the project, steel slag mixture is applied to the pavement surface layer and base layer. SMA-13 and AC-16 steel slag asphalt mixture surface test sections, and the cement stabilized steel slag gravel mixture and cement fly ash stabilized steel slag gravel mixture base layer test sections are laid. The test indexes of the test sections are studied and tracked. The results show that the relevant technical indexes of the test sections meet the requirements of specifications, and there are no obvious defects during operation, which verifies the reliability and feasibility of the steel slag mixture in the pavement surface layer and the base layer.
