Abstract: This paper investigates on the possibility of improving and comparing the engineering properties of three samples of lateritic soil from Ogun, Oyo and Osun with pulverized cow bone, a processed animal waste obtained from abattoirs, for road construction. The effect of PCB on the soil samples was assessed by adding 2-8% PCB at a 2% increment to the lateritic soil. The Atterberg limits(Liquid limit, Plastic limit, Plasticity Index) obtained were Ogun ( 57%, 21.16%, 35.84%), Oyo (51.4%, 25.19%, 26.21%) and Osun (29.4%, 14.68%, 14.72%). The high plasticity index of the Ogun state soil shows that the soil may be susceptible to cracking and shrinkage. Although the strength properties, California Bearing Ratio and Unconfined Compressive Strength of all the samples improved with increment in PCB additive from 0 - 8% PCB achieving the following peak (Soaked CBR, UCS) values with PCB stabilization; Ogun(15%, 93.37%), Oyo(19.65%, 95.19) and Osun(18%, 171.315%), the compaction result did not concur with the endless addition of PCB to the lateritic samples.
