• Abstract:

  Stabilization Is The Process Which Involves Enhancing The Physical Properties Of The Soil In Order To Improve Its Strength, Durability Etc., By Blending Or Mixing With Additives. The Different Types Of Methods Used For Soil Stabilization Are; Soil Stabilization Using Cement, Soil Stabilization Using Lime, Soil Stabilization Using Bitumen, Chemical Stabilization And A New Emerging Technology Of Stabilization That Is Stabilization Of Soil By Using Geo-synthetics. Geo-synthetics Are Synthetic Products Made From Various Types Of Polymers Which Either Woven Or Non-woven .These Are Used To Enhance The Characteristics Of Soil And Have Provided A Practical Way Of Constructing Civil Engineering Structures Economically. In This Study, The Results Of Studies On The Performance Of Geogrids Within Sub Grade Soils Are Carried Out Experimentally Utilizing The California Bearing Ratio (CBR) Testing Arrangement. The Sub Grade Soil Is Subjected To The Following Laboratory Tests; Particle Size Analysis, Atterberg’s Limits, Specific Gravity Test, Compaction Test And CBR Tests Are Conducted On Soil Samples With And Without The Inclusion Of Geogrid Layer And Also By Varying The Position Of It In The Mould. Use Of Geogrid Increases The CBR Value Of The Sub Grade And Thereby Reduces The Pavement Thickness. It Reduces The Intensity Of Stress On Sub Grade. It Was Found That For The Two Samples The CBR Values Increased At 3H/4 Height When Compared To H/2,H/4 Heights From The Bottom. The Optimum Height Of Placement Was Found At A Height Of 3H/4 From The Bottom.
