Contact stresses at the tire/pavement interface for a stationary or rolling wheel comprise not only of vertical stress compounds but also centripetal stress as well. In this research, wheel load in the form of conically distributed centripetal load and uniformly distributed vertical load were considered and a new development for a closed form solution was introduced. The solution was utilised to analyse a three-layered pavement structure in order to clarify the influence of centripetal load on the pavement responses. Higher tensile stresses at the surface of the pavement along the edge of the load were found. Furthermore, tensile stresses were found at the bottom of the top layer below the centre of the load
