Coal mining operation results in two general types of by-products. One is coarse coal refuse and another is fine coal refuse which is also termed as coal mine dust. In coal mine during the mining process a lot of coal mine dust produce. Proper disposal of this is a great problem. This research investigated on the use of nontraditional construction materials, specifically coal mine dust as an engineering material in subgrade of road construction. This investigation consist of performing laboratory tests to determine the engineering properties of the coal mine dust available at coal mine site. Along with the coal mine dust, local sand also used for improving the geotechnical properties of their mixture. MDD and CBR values were performed at first for coal mine dust and local sand sample alone and then for coal mine dust with sand in different proportions. Then the result is compared with the requirements of LGED, Bangladesh to find out the suitable samples for road sub-grade. So, according to the results found and “Road Pavement Design Manual-1999”, it may be recommended that 30% coal mine dust mixed with 70% sand would be suitable for road subgrade construction.
