This report is the first in a series regarding a study entitled "Evaluation of Truck Sizes, Weights, and Tire Pressures on Pavement Deterioration", being conducted by the Center for Transportation Research at The University of Texas at Austin. The overall study examines several aspects of possible cause and effect relationships between increasing truck weights, sizes, tire pressures and pavement deterioration. The first phase of this study includes three scenarios. The first is a base scenario, which is characterized by an assessment of the effects on pavements of the entire vehicle fleet operating with currently prescribed weight limits and pre 1973 tire pressures. The second is an existing traffic scenario, characterized by the most recently observed (1984) SDHPT vehicle weight data and tire pressures. The third is a future traffic scenario, whereby hypothetical vehicle configurations are utilized to evaluate a possible way of reducing pavement damage.
