Abstract EN
This study was carried out to evaluate the effect of bagasse ash (BA) on the California bearing ratio of lateritic soil.
Laboratory tests were performed on natural and bagasse ash treated soil samples in accordance with BS 1377 (1990) and BS 1924 (1990), respectively.
Treated specimens were prepared by mixing the soil with bagasse ash in steps of 0, 2, 4, 6 and 8 % by weight of dry soil.
The preliminary investigation carried out on the natural lateritic soil shows that it falls under silt-clay material of Group A-6 using AASHTO classification and inorganic clay material CL according to Unified Soil Classification System (USCS).
The specific gravity of the soil samples decreased from 2.61 for the natural soil to 2.48 at 8% bagasse ash content.
The liquid and plastic limits increased from 36.32 and 21.30%, respectively, to 38.00 and 21.54% both at 2% bagasse ash content.
The maximum dry density (MDD) of the soil increased from 1.48 Mg/m3 for the natural soil to a peak value of 1.49 Mg/m3 at 8% bagasse ash content.
The Optimum Moisture Content (OMC) increased from 18.5% for the natural soil to 19.0% at 2 and 4% bagasse ash content and then decreased.
The unsoaked California bearing ratio values from 4% BA content and above met the minimum CBR value of 30% specified by (BS 1990) for materials suitable for use as base course material when determined at MDD and OMC.
However, the highest CBR value of 62% recorded at 8% BA content failed to meet the 80% CBR value recommended by the Nigerian general specification (1997) for cement stabilization.
Bagasse ash improved the CBR value of lateritic soil when compacted at optimum moisture content and maximum dry density.
