Stabilization of Lateritic Soil for Road Application Using Lime and Cow Bone Ash

Roads should possess sufficient strength to support wheel loads imposed upon them either during construction or the service life of pavement. It is sometimes necessary treat soils provide a stable subgrade working platform for road surface. Cow bones scattered in Nigerian meat markets and abattoirs have become an environmental concern, hence need seek alternative uses them. This study concentrated on stabilizing potential cow bone ash (CBA) as eco-friendly bio-waste material lime stabilization lateritic soil application. aimed at achieving effective utilization practicable by attempting identify best percentages stabilizers (binders) needed improve soil. Based this, identified methods that were used samples obtained from Ado-Ikere road, Ado Ekiti state, Nigeria method using sample. The following laboratory tests experiments carried out: sieve analysis, atterberg limits, compaction, california bearing ratio (CBR) thermo-scientific X-ray fluorescence (XRF). They investigate influence Different (2%, 4%, 6%, 8% 10%) respectively samples. Also, different proportions addition explored stabilize CBR test results showed 8%, being optimum amount binder CBA increased also revealed can be
