Analytical Study of Flexible and Rigid Pavement Subjected to Combined Bending and Shear by Ansys.

The analysis of flexible and rigid pavement is a difficult, because of the pavement system is multilayered and three dimensional. To provide accurate displacement, strain and Stresses, the system must consider the different characteristics of each layers. This paper represent that behavior of the flexible and rigid pavement under transient pressure by using finite element analysis. Both the pavement have been analyzed by taking section properties of length 25m width 7.75m and total thickness for flexible pavement is 0.665m and total thickness for rigid pavement is 0.6m. In flexible pavement we have taken sub base course, base course and asphalt surface course and for rigid pavement base course and concrete layer. After that assigning the suitable material properties and support condition analysis is done. This study shows that effect of increase of pressure with time on deflection, stress and strain in both rigid and flexible pavement.
