Abstract: In the present study, an attempt is made to use Kota stone mining, cutting and quarry waste as a full replacement to conventional aggregate in Granular Subbase Course (GSB). For the study, Kota stone mining waste was hand crushed into aggregates of the desired size and evaluated for physical and mechanical parameters as per Ministry of Road Transportation and Highways specifications (MoRT&H 2013). Kota stone quarry waste and slurry waste is used as fines and screening. Modified proctor test was conducted to find optimum moisture content (OMC), and maximum dry density (MDD) for all the six grading and soaked California bearing ratio (CBR) was performed to analyse mechanical properties of the mix. From the result of this experimental research, it is observed that Kota stone mining and slurry waste satisfies parameters specified by MoRT&H 2013 and can be used as GSB material in the flexible pavement.
