Soil Improvement By Using Jute Geotextile and Sand-A Comparative Study

The Good Connectivity To Any Part Of The Country In All Seasons Is The First Step To Develop The Infrastructure Of The Nation. The Structure Of Road Consists Of The Formation Or Subgrade And The Pavement. The Structural Element Of The Pavement Is The Foundation (Soiling Or Bottoming) Also Called The Sub-Base Of The Base. The Base May Be Surfaced Either With A Concrete Or A Bituminous Surfacing.Subgrade Is And Integral Part Of Road Pavement Structure As It Provides Support To The Pavement As Its Foundation. The Main Function Of The Subgrade Is To Give Adequate Support To The Pavement And For This The Subgrade Should Possess Sufficient Stability Under Adverse Climatic And Loading Conditions. The Formation Of Waves, Corrugations, Rutting And Shoving In Black Top Pavements Are Generally Attributed To Poor Subgrade Conditions.Geotextile, Both Natural And Synthetic, Are Helpful In Improving The Geotechnical Properties Of Soil. These Fabrics Are Used For Erosion Control, Drainage, Filtration, As Separation Layer, For Vegetation Support Etc. Jute Is Also A Geotextile Which Is More Ecofriendly And Can Be Used In Road Works Cost Effectively.
