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.
