The utilization of non conventional waste materials like steel slag, copper slag, Scrap Tyres, fly ash etc. in road construction activities is gradually gaining significant importance in India. Owing to the increase in construction cost of roads at an alarming rate there is an increase in the cost of conventional road materials. Steel slag is a waste material produced as a by-product during the oxidation of steel pellets in an electric arc furnace. This by-product can be used as replacement of aggregates in pavement layers. Due to increase in the motor vehicles day by day tends to increase in heaps of discarded rubber tyres. One of the main issues associated with the management of scrap rubber tyres has been their proper disposal. A study was conducted to investigate the possibility of using Granulated Blast Furnace Slag (GBFS) and also with Waste Rubber Tyre (WRT) with various blended mixes of conventional aggregates in subbase layer with different percentages separately. This study also presents the result of experimental investigation on the influence of Rice husk ash (RHA) on the index properties of Red soil which is used as filler material in subbase layer
