Abstract
Coalwash (CW) is granular waste by-product that results from the operation of the local coal mining industry. The reuse and recycling of this material in earthwork construction project as landfill option, is attractive from both economic and environmental perspectives. This paper presents an experimental study on compacted CW material prepared at different relative compaction levels. First the basic materials index properties are described and the stress-dilatancy behaviour is examined through a series of drained triaxial compression tests. The experimental data suggests that the different relative compaction levels exhibit different stress strain behaviour but show some degree of similarity in terms of the stress-dilatancy relationship.
