AbstractCombined influence of temperature and mechanical deformations define the resulting contact stresses, heat flow, and rolling loss at the tire–pavement contact. In this study, the thermomechanical coupling of a hyperviscoelastic tire with a deformable pavement layer revealed the impact and extent of temperature influence on the hysteretic loss of a rolling tire. A scheme to predict the three-dimensional contact stress distribution was established that incorporated the thermomechanical interaction between a rolling hyperviscoelastic truck tire and a deformable pavement layer. The fully coupled thermal-stress model addressed two distinct yet intertwined perspectives: (1) establishing a thermomechanical database and prediction tool to generate contact stresses as inputs for pavement structural design, and (2) quantifying the associated rolling loss at the tire–pavement interaction that relates to tire design configurations and environmental impacts. Differences in the resulting contact stresses and rolling energy loss were observed between imposing uniform and nonuniform temperature profiles. Both the range and magnitudes of stresses throughout the tire–pavement contact imprint changed drastically as varying temperature profiles were implemented. Ranking the influence of thermal boundary conditions, the ambient temperature induced the highest impact on the dissipation energy and change in contact stress distribution, followed by the road and inner tire surface conditions. Moreover, the global hysteretic loss within the tire as myriad temperature profiles were imposed did not change significantly; however, the creep dissipation observed within the contact imprint revealed a higher disparity.Practical ApplicationsIn this study, a finite-element model was established to simulate a free-rolling truck tire over a pavement layer and determine the combined influence of temperature and loading on the three-dimensional contact stresses and hysteretic loss. The thermomechanical interaction between the truck tire and pavement layer impacted both the range and magnitude of the contact stresses, wherein differences were observed between imposing uniform and nonuniform temperature profiles. Particularly, the ambient temperature had the highest impact on the contact stress distribution and dissipation energy, in contrast to the level of influence from the pavement surface temperature and internal tire air temperature. In lieu of complex models, nonlinear regression equations were developed as a simple means to generate three-dimensional contact stress inputs for pavement analysis. Future model improvements and considerations may include other rolling conditions, such as braking, accelerating, or cornering conditions; temperature-dependent tire-inflation pressure and interface friction; influence of air and sun through convection and radiation along with daily temperature cycles; and a viscoelastic asphalt pavement layer.
