The demand for utilization of industrial by products and wastes in road pavement is increasing and becoming more important. Government policies and public awareness is also contributing in the enhancement of both this demand and utilization. Around 4000 marble mines and 1100 marble processing units are spread all over India. Near about 5-6 million tones/year of marble dust is generated and is disposed of on road sides causing environmental degradation, drainage problem and damaging agricultural land. The gradation curve of the sieve analysis resulted that the soil is sandy associated with silt of low compressibility(SM- Silty Sand). The CBR (California Bearing Ratio) value and UCS (Unconfined Compressive Strength) of soil gives the clear idea about the quality of sub-grade material to that of the required as per IRC (Indian Road Congress) Code. The CBR was carried out in soaked and un-soaked condition and all the other parameters including the thickness of sub-grade were kept constant.
