Abstract

Lime Stabilization is the modern method of Improving physical and chemical properties of soil, this method expected to improve the Performance of Flexible Pavement by treating the Sub-base Materials locally available in the Construction corridor by Lime. The objective of this paper is to evaluate the performance of Flexible Pavement by treating the sub-base materials by Lime and was meant to analyse the CBR and UCS as the measure of the Performance of Flexible Pavement. Materials was classified as Clayey Gravel contained 61.9% Gravel and 28.5% Clay, either material were having a PI of 25% and Liquid Limit of 40.8% wand classified as Clay with low Plasticity. Investigation showed that as the increase in Lime content the CBR values increased by 20.9% at 10% Lime content which gave a CBR value of 22.4% while at 0% was 4.7% but beyond 10% Lime Soil exhibits decrease in CBR. Either as the increase in Lime content the UCS has shown an increase by 24% where at 2% UCS value was 0.8Mpa and at 10% UCS value was 3.2Mpa after seven days curing and submerged into water for four hours as per standards. From the discussion of results as the study jointly analysing the associated factors for the Performance of Flexible Pavements which were CBR and UCS, therefore it was established the optimum Lime content of 10% gives the maximum strength as such Locally available soil along the construction corridor can be used as the Sub-base materials with high Performance of Flexible Pavement.
