Flexible Pavements Traditionally Consist Of Bituminous Surfacing, Granular Base/Subbase And Subgrade Soils. Granular Materials Are Used For Bases And Sub-Bases Of Flexible Pavements Both For Low And High Volume Roads. Pavements Of Low Volume Roads Have Thin Bituminous Wearing Courses Such As 20mm Premix Carpet Or Single Coat And Two Coat Surface Dressing. Thick Bituminous Surfacing In The Form Of Dense Bituminous Macadam And Bituminous Concrete Are Used For High Volume Roads. The Pavements For Low Volume Traffic Can Be Considered As A Two-Layered System Consisting Of Granular Base And Subgrade Soil While The High Volume Roads Can Be Considered As Multi Layered Systems. Granular Layers Constitute A Major Portion Of The Thickness Of Low As Well As High Volume Roads. It Is, Therefore, Necessary That The Behavior Of Granular Layer Is Well Understood By Pavement Designers In Order To Optimize The Pavement Construction. Resilient Modulus Of Subgrade Soil Is An Essential Input For Analysis Of Flexible Pavements Using Linear Elastic Layered Theory. Most Of The Agencies Specify That Resilient Modulus Of Subgrade Soil Is To Be Determined By Conducting Repeated Load Triaxial Test On Cylindrical Specimens Of Soil Prepared Using Appropriate Moisture Content And With Selected Compaction Effort. However, Considering The Complexity Of Conducting The Repeated Load Test, Resilient Modulus Value Is Often Estimated From Different Soil Parameters, Which Can Be Determined With Relative Ease Compared To The Resilient Modulus Test. The Parameters That Have Been Empirically Correlated With Resilient Modulus Include California Bearing Ratio (Cbr) And Index Properties Such As Plasticity Index. Correlations Are Also Available For Selecting In-Situ Mr Value From The Dynamic Cone Penetrometer (Dcp) Value Determined On In-Service Subgrade Layer. Since Most Of The Empirical Equations Relating Resilient Modulus With Dcp Value And Cbr Of The Subgrades Are Soil Specific, It Is Necessary To Develop Empirical Equations For Soils Available In The Eastern Part Of India And Considering The Need For Providing Simplified Approaches For Selection Of Resilient Modulus, This Aspect Also Has Been Considered In The Present Investigation.
