Wastes generation has increased year by year and the disposal becomes a serious problem. It is therefore necessary to utilize the wastes effectively with technical development in relevant field. Soil stabilization through the reinforced soil construction is an efficient and reliable technique for improving the strength and stability of soils either for road construction or to mitigate the effects of loads from accidental explosions. In this study, lateritic soil was taken from a borrow pit located along Papa-Ilaro road Ajegunle at Abalabi, via Ilaro, Ogun State, Nigeria and the solid plastic was taken from different waste locations in Ilaro. The plastic was grounded into pellets and were sieved to determine the particle size distribution. For laterite mix, plastic pellets were substituted in the lateritic soil at 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8% and 9% with 0% serving as control. The tests conducted in line with BS 1377 (1990) are the moisture content, specific gravity and compaction. From the soil classification, it was observed that the lateritic soil sample is sandy-clay-loam. It was also observed that plastic pellets slightly increases the bulk densities and dry densities in the same proportion at 1% to 9% plastic as the percentage water content increases. From the results, plastic pellets could be used as stabilizing material for road construction. This will reduce the environmental risk and hazard caused by plastic waste/
