Abstract	Nowadays, usage of waste products as an alternative in construction industry has become necessary for achieving sustainable development. Generation of stainless steel from iron ore may release many harmful substances, one such is Ferrochrome steel slag (FCSS). Ferrochrome steel slag is a waste product generated during the production of stainless steel. It has been used as an aggregate in porous asphalt mixture. Disposal of ferrochrome steel slag into the environment may rise hazardous environmental issues. Porous asphalt mixtures are used as surface wearing course as they have greater resistance to skid. Required laboratory tests on aggregate and bitumen will be performed to determine desired bitumen content and to analyse the aggregate properties. Aggregate composition will be replaced with varying percentages of ferrochrome steel slag from 5% to 25% to obtain the accurate sample for replacement. Marshall stability test will be carried out on the replacement sample for determining optimum percentage of replacement for acquiring good strength and resistance
