摘要：	Coal-reject is the waste resulting from the separation of genuine coal from a jumble of other mined out materials. After extraction of the valuable coal the coal- rejects are generally dumped or stored in site close to coal wash yard. Construction of highways, major part of infrastructure development has resulted in using vast tract of natural resources. This paper discusses characterization of coal-reject as a pavement material based on laboratory finding. The geotechnical properties such as grain size distribution, specific gravity, compaction characteristics, shear strength and California bearing ratio (CBR) of coalreject and coal-reject stabilized using Portland cement is presented. Based on the above results it was observed that coal reject can be used as a marginal highway pavement material.
