Evaluate Truck Tire Types on Top-Down Cracking and Instability Rutting Based on BISAR Analysis

The effects of truck tire types on pavement responses were evaluated via BISAR analysis. The loading configurations for three types of truck tires (11R22.5, 425/65R22.5 and 445/50R22.5) for BISAR input were created based on their tire footprints. The magnitude and orientation of three-dimensional (3-D) contact stresses was reasonably defined for different tires based on measured contact stresses and previous studies. For all cases without considering unbalanced dual tires, super single (425/65R22.5) produced the worst damage to pavement in terms of top-down cracking and instability rutting, while new generation wide-based tire (445/50R22.50 caused the least damage to pavement. If unbalanced load between dual tires was considered, however, dual tires might produce much more damages to pavement than super single tire.
