ABSTRACT

Abstract: The important factor for design and construction of pavement is the behavior of underlying sub-grade. Large deformations in the sub-grade will lead to a continuous deterioration of the paved surface. As the sub-grade soil is too weak to bear the load, engineering solutions such as geo reinforcement using geo-synthetics are additives which are earlier used in sub-grade improvement and such experimental study is carried by pervious authors. This paper deals with the sub-grade improvement using geo-textile as a reinforcement sheet and quarry dust as admixtures. In order to increase the strength of the sub-grade the quarry dust is varied with different percentages i.e., 0%, 5%, 10%, 15%, 20% and 25%. In this study, Proctor’s compaction tests, and CBR soaked and unsoaked tests are conducted on locally available soil with reinforced material and with admixture. For this study it is identified that the engineering properties of the soil is improved in all conditions. The soil with quarry dust at optimum value is 20% has CBR soaked value is obtained 6.83% and unsoaked value is obtained 7.02% is increased when compared with conventionally soil. The soil, quarry dust at optimum value is at 20% and Geo-textile has CBR soaked value is 6.59% and unsoaked value is 8.95% is increased when compared with conventionally soil and soil with quarry dust.
