Fly ash is a byproduct causes environmental pollution. Every year remarcable amount of ferming land is used for it’s disposal. But it has some geotechnical properties which we can use for civil engineering pueposes. The present study aims at development of specifications for use fly ash in road construction and their suitability in improved sub-grade of a road pavement. Laboratory proctor Test for MDD and CBR Test for CBR values were performed at first for fly ash and sand sample alone and then for fly ash with sand in different proportions. Then the result is compared with LGED, Bangladesh requirements to find out the suitable samples for road sub-grade. According to ROAD DESIGN STANDARDS, RURAL ROAD (2005) published by LGED and JICA- required CBR for improved sub-grade material for low and medium traffic road construction is 8%. In this study it is found that, upto 40% fly ash mixed with sand gives more than 8% CBR. So, at most 40% fly ash may be used as a supplement of sand for improved subgrade.
