Different pavement design approaches. General framework for pavement design. Traffic Considerations in Pavement Design: Vehicle types. Axle configurations. Contact shapes and contact stress distributions. Concept of standard axle load. Vehicle damage factor.
Flexible Pavement Analysis: Material Characterization Traffic Loading Stresses and Deflections: Asphalt Mix Design. Theoretical models such as linear elastic layered theory. Discussion of the need for use of advanced analytical techniques for flexible pavements. Discussion of different software available for analysis of flexible pavements
