Optimum Utilization of Marble Dust for Stabilization of Sub Grade and Its Fatigue and Rutting Behaviour of Flexible Pavement

Abstract

Use of industrial waste for soil improvement is efficent and cost effective. Sublevel adjustment of soil is essential and considerable procedure for the development of roads and hinghway.Therefore it is important to understand the properties of these waste for understanding their performance level.This study define a model depend upon genetic algorithium .In this study ,marble dust was added for the stablization of soil which was collected from the Gharuan , Punjab.This soil was group into CL based as Indian Standard Classfication System (ISCS). In this investigation marble dust was added 10% 15 % 20% and 25 % with respect to the weight of soil .Index properties (liquid limit, plastic limit, plasticity index) were rated as different percentages of marble dust is specifed above .In a similar way , (UCS) Unconfined compressive strength and(CBR) California Bearing Ratio Test was calculated at (OMC) Optimum Moisture Content which determined through Proctor test for the modified and parent soil.
Observations based totally on tests specific above showed 20% of waste marble dust to be most effective for strengthening of the discern soil.
Also, the assessnent of observe CBR value with the expected CBR value which was
calculated thrugh the regression analysis using SPSS was done.
From the equation of Heukelom and Klomp, Thompson and Robnett, Transportation and Road Research Laboratory, Erdem Çöleri Resilient Modulus was calculated for the subgrade soil.
Based at the results acquired, pavement thickness was decided for designing
flexible pavement phase as according to IRC 37-2012.
