Effect of California Bearing Ratio on the Properties of Soil
Journal Title: American journal of Engineering Research - Year 2016, Vol 5, Issue 4
Abstract
Pavements Are A Conglomeration Of Materials. These Materials, Their Associated Properties, And Their Interactions Determine The Properties Of The Resultant Pavement. Thus, A Good Understanding Of These Materials, How They Are Characterized, And How They Perform Is Fundamental To Understanding Pavement. The Materials Which Are Used In The Construction Of Highway Are Of Intense Interest To The Highway Engineer. This Requires Not Only A Thorough Understanding Of The Soil And Aggregate Properties Which Affect Pavement Stability And Durability, But Also The Binding Materials Which May Be Added To Improve These Pavement Features. The Supporting Soil Beneath Pavement And Its Special Under Courses Is Called Sub Grade. Compacted Sub Grade Is The Soil Compacted By Controlled Movement Of Heavy Compactors. The Performance Of Pavements Depends To A Large Extent On The Strength And Stiffness Of The Subgrades. Among The Various Methods Of Determining The Strength Of Subgrade The CBR Test Is Very Important. The Design Of Flexible Pavement Takes Into Account Some Important Parameters Such As Traffic Load, Material Properties Of Layers And Sub Grade Soil Properties. California Bearing Ratio Is Defined As The Ratio Of Load Required To Cause 2.5mm Or 5mm Penetration To The Standard Load Which Replaced By Material. After Getting The CBR Values Analysis Is Carried Out And Relationships Are Established Between CBR And All The Fundamental Properties Of Soil In Order To Determine Which Properties Of Soil Has More Or Less Influence. Mathematical Concepts Of Linear Regression, Power Series And Linear Series Are Applied So That Proper Relationships Are Established. In Order To Test The Validation Of The Established Relationships The Chi-Squared Test Is Carried Out. Finally, For The Design Of Flexible Pavement Parameters Such As Annual Daily Traffic, Lane Distribution Factor, Vehicle Damaging Factor, Design Traffic In MSA. Using These Data The Required Thickness Is Calculated As Per IRC: 37-2001 Guidelines.
