Abstract
Abstract - Stabilization is the modern Technique of Improving physical and chemical properties of soil, Stabilization of Granular Soil can be done by either Lime, Cement and other materials like Stone Dust which in turn the Geotechnical properties of soil may be improved. In this paper materials were investigated by adding percentage of Stone Dust on the Lime treated soil by 10% of Lime and observe the improvement of Geotechnical properties. This method expected to improve the Performance of Flexible Pavement by treating the Sub-base Materials locally available in the Construction corridor by Lime and Stone Dust. The objective of this paper is to evaluate the effects of granular materialsafter adding 10% Lime and varying the percentage of Stone Dust 5%, 10%, 15%, 20%, 25% and 30% by analysing CBR and UCS as the measure of the Performance of Flexible Pavement.Investigation showed that as the increase in Lime content the OMC were tend to increase and MDD exhibit to decrease but after the addition of Stone Dust MDD increases with the increase in Stone Dust to a certain percentage and then starts to decrease due to the mixing of heavy particles of stone dust in significant amount where at 30% Stone Dust MDD decreases and OMC increases. CBR values increased by 20.98% at 10% Lime content which gave a CBR value of 22.4% while at 0% was 4.7% after the addition of Stone Dust CBR observed to be improved from 22.4% to 47.1% at 30% Stone Dust which is equivalent to 47.6%.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 3.3Mpa after seven days curing and submerged into water for four hours as per standards, as the addition of Stone Dust on the 10% Lime treated Soil UCS values has been increases slightly from 3.3Mpa to 4.76Mpa at 30% Stone Dust + 10% Lime. 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 10% Lime + 30% Stone Dust content of and established.
