The structural adequacy of rigid pavement can generally be get predicted based upon its structural response to the applied loads mostly in terms of deflection and stress, In the present study, Rigid roadway pavement is modeled as a rectangular plate supported by elastic soil foundation having sub grade modulus (K) which permits only downward deformation of mass i. e. no horizontal deformation. The class A static load is applied to pavement having different thickness from 150mm to 300mm and analysis using computer software STAAD-PRO and manually by Westergaard analysis theory performed and the results are obtained which shows inverse relation between thickness and deflection then analysis is further extent for pavement consist of 30 percent recycled concrete aggregate having different properties like density, modulus of elasticity and compressive strength are presented graphically for comparison study to clearly marks the green and sustainability concept and increase thickness provides eco-friendly economy, strength and increase life span to road pavement as well as safety to road user.
