| Abstract: | Based on the method in Test Methods of Materials Stabilized with Inorganic Binders for Highway Engineering,the technical performances of lime fly ash stabilized iron tailing gravel in highway application were researched by systemic experiments in this paper.These include the strength,modulus,and frost resistance property,water stability.And the influence factors of the mixture strength were analyzed,too.Then,the mechanism of lime fly ash stabilized iron tailing gravel in strength was expounded.The results show that the mixture of lime fly ash stabilized iron tailing gravel has higher strength and modulus,good frost resistance property and water stability.The technical performances of lime fly ash stabilized iron tailing gravel conform to the current specification,so it can be used as sub-base course or base course material. |
