The research investigates the effects of cow bone ash (CBA) on the chemical and geotechnical properties of lateritic soil for road construction and also relieve the environment from the menace of environmental pollution, arising from indiscriminate disposal of this waste. Cow bone ash (CBA) was used in stabilising lateritic soil at ratios 0, 2, 4, 6, 8 and 10% of disturbed soil sample (fine - grained i.e. silt-clay material) collected from New Ado Iyin Road. The soil sample was subjected to laboratory tests such as Specific gravity, particle size distribution, Atterberg limits, compaction, California bearing ratio and unconfined compressive strength in accordance with British Standards (BS 1377: 1990 and BS 1924: 1990). Optimum of addition of cow bone ash was achieved at 6%. The investigation on the soil sample revealed that a gradual decrease in the results of compaction characteristics, CBR and UCS as decreased was recorded before it further increased with increased in CBA content. Optimum of CBA was recorded at 6% which is best suitable for silt-clay soil. Further study to examine the long term performance of cow bone ash in soil stabilization should be examined.
