| 摘 要： | 对铁尾矿砂及尾矿砂加入石灰水泥后的物理力学性能进行了试验研究，并与石灰土进行对比。结果表明：铁尾矿砂掺加石灰、水泥后，其强度随着龄期而增长，具有半刚性材料的特性，用石灰、水泥稳定尾矿砂作为路面基层材料具有很好的路用性能，同时用石灰和水泥稳定的效果更佳。

| Abstract: | This paper investigated the physical mechanics properties of iron tailings sand and iron tailings sand mixed into lime and cement, and compared it with lime-clay. The results show that the mixture strength of iron tailings sand and lime or cement grows as the age grows, and the iron tailings sand stabilized with lime or cement has great pavement performance as road base materials, the better effect is from the mixture of lime, cement and the iron railings sand. |
