An attempt to stabilize some soils from failed sections of the Sagamu–Papalanto road, southwestern Nigeria with lime was undertaken with a view to improve the geotechnical properties of the soils. The soils were treated with 0 % to 20 % by mass of lime, compacted at the Modified AASHTO level and subjected to consistency limits, unconfined compressive strength (UCS) and California bearing ratio (CBR) tests. Increasing content of lime addition resulted in soils with reducing plasticity with an optimum range of 6 % to 8 % while the UCS and CBR increased. Furthermore addition of between 6 % and 10 % of lime produced soils with desirable strength for use as base course materials. However despite the continuous increase in CBR with increasing lime addition, none of the soils meet the unsoaked CBR requirement for use as base course materials. However the soils qualify for use as subbase materials. Thus, it can be concluded that, the soils responded positively to lime addition; however the degree of response and the eventual effect on its suitability for use varied from soil to soil.read more

A review of the use of lateritic soils in the construction/development of sustainable housing in Africa: A geological perspective
TL;DR: Lateritic soils have been described as highly weathered tropical or sub-tropical residual soils with varying proportions of particle sizes ranging from clay size to gravel, usually coated with sesquioxide rich concretions as discussed by the authors.

Geotechnical characterisation of lateritic soils from south-western Nigeria as materials for cost-effective and energy-efficient building bricks
TL;DR: Lateritic soils which have been described as highly weathered tropical or subtropical residual soils were studied with an attempt to establish its suitability or otherwise as sustainable material in building bricks and housing development that will meet the present challenge of sustaining the environment without costing too much and maintaining a high standard of strength, durability and aesthetics as discussed by the authors.

Comparative Assessment of the Stabilization of Lime-Stabilized Lateritic Soil as Subbase Material Using Coconut Shell Ash and Coconut Husk Ash
TL;DR: In this article, the effect of two agro-based admixtures (coconut shell ash (CSA) and coconut husk ash (CHA) on lime-stabilized lateritic soil were assessed and their results were compared with respect to the most potent stabilizer that can be used for the stabilization of lateritic soils as sub-base material in this study.
