Virginia Transportation Research Council research report

Higher tire pressures create higher stresses in the pavement. A thicker HMA layer is better able to resist rutting in the sense that the layer is usually stiffer. Finally, truck wheel wander can influence rutting. The increase in wheel wander can increase the amount and distance of lateral movement in the pavement.
