Abstract

Non - lateritic soils are commonly used for construction purposes. However, due to the variability of the properties of the soil, it does not meet the design requirement. In this study non - lateritic soil sample was taken from a borrow pits in Dungulbi (Bauchi-Gombe road, Bauchi State Nigeria). The materials were characterized and then stabilized with scrap tyre crumb rubber (STCR) in stepped concentration of 1, 2, 3, 4 and 5 % by dry weight of the soil for various sizes of scrap tyre crumbs rubber (STCR) in the range (i.e 0.212, 2.36, 3.35 and 4.75 mm). The test conducted on the non - lateritic soil- STCR include compaction using three energies level (i.e British Standard light, BSL, West African Standard, WAS, British Standard heavy, BSH) and California bearing ratio (CBR). The results obtained, indicate a general decrease in both optimum moisture content (OMC) and maximum dry density (MDD) as the STCR contents increases. There was increase in CBR values for both unsoaked and soaked condition up 3 % STCR replacement thereafter decrease with increase in STCR. Statistical analysis were also carried out using analysis of variance (ANOVA) to check the effect of STCR inclusion on the geotechnical properties of the non - lateritic soil to be used as a road construction material. The results of the multiple linear regression analysis showed that the predicted values are in good agreement with the experimental values. The stabilized soil showed satisfactory strength and can be used for construction of embankment and stabilization of subgrade, subbase and base course of road. This indicates the potential of using 3 % STCR for non – lateritic soil stabilization.
