Abstract:

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.
