Abstract

This study considered the used of lime to stabilized lateritic soil to be used as landfill liner and cover material. The laterite soil used for this study was collected by method of disturbed sampling from a laterite soil formation located in Shika, Zaria, Kaduna state (Latitude 11015ꞌ N and longitude 70 45ꞌ E). It was treated with lime at 2%, 4%, 6% and 8% lime content. The result of index properties of the soil were determined as liquid limit 47.0%, plastic limit, 27.30%, plasticity index 19.70%, shrinkage limit 22.86% and specific gravity 2.63. Which revealed that the soil belongs to the A-7-6 (12) group according to the AASHTO (1996) classification system, and is classified as CL (Low clay plasticity) under the Unified Soil Classification System (USCS, ASTM 1992). The soil appears grayish-black in colour, transitioning between shades as it moves from wet to dry conditions. Compaction results revealed that the untreated soil exhibited lower maximum dry density (MDD) and higher optimum moisture content (OMC) due to the lubricating effect of residual crude oil. Vermi-remediation improved soil structure, resulting in more defined compaction curves. British Standard Light (BSL) compactive effort produced the lowest MDD and highest OMC This trend is attributed to increased water demand associated with lime hydration and pozzolanic reactions. Despite the reduction in MDD, lime-treated soils exhibited more uniform and stable compaction behaviour. Lime contents, typically between 4% and 6% achieved successful results.
