This Study Aims To Investigate The Effect Of Glass Fiber And Rubber On The Properties Of Expansive Soil And Its Suitability As Subgrade Reinforcement In Road Applications. The Maximum Dry Density (MDD), Optimum Moisture Content (OMC), And California Bearing Ratio (CBR) Were Evaluated For Varying Percentages Of Glass Fiber And Rubber In The Soil. The Results Showed That The Addition Of Glass Fiber And Rubber Had A Positive Effect On The Soil Properties. The MDD And CBR Increased With Increasing Fiber And Rubber Content, While The OMC Decreased. Additionally, The Reinforced Soil Exhibited A Significant Improvement In Strength Compared To The Unreinforced Soil. The Study Suggests That The Incorporation Of Glass Fiber And Rubber Can Enhance The Performance Of Expansive Soil As Subgrade Reinforcement In Road Applications.
