Research on application of iron tailings on road base

Abstract

In order to make good use of waste iron tailings considering energy conservation and environment protection, a new research on the use of tailings in road base has been carried out in this study. A type of iron tailings stabilized with cement made of appropriate amount of cement was firstly selected as the semi-rigid base material. After the mix proportion design based on material characteristics, compaction tests, unconfined compression tests and economic analysis were conducted on the mixture. It shows that iron tailings stabilized with cement with a more than 15% cement content meets the test requirements well and can be applied on the base and subbase course of low-grade highway. Helping to save road materials and reduce project costs, the study has a promising application prospect. © (2013) Trans Tech Publications, Switzerland.
