Book Description
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.

Book Description
To help assess proposals for further changes in federal truck weight limits, Congress requested this study through Section 158 of the Surface Transportation and Uniform Relocation Assistance Act of 1987. To conduct the study, the National Research Council convened a special Transportation Research Board committee with experts in pavements, bridges, highway safety, freight transportation economics, motor vehicle design, highway administration, motor carrier operations, and enforcement of motor vehicle regulations. The study focused on four issues identified in the study request that involve potential changes to federal weight limits for Interstate highways: (1) Elimination of existing grandfather provisions; (2) Alternative methods for determining gross vehicle weight and axle loadings; (3) Adequacy of the current federal bridge formula; and (4) Treatment of specialized hauling vehicles--garbage trucks, dump trucks, and other trucks with short wheel bases that have difficulty complying with the current federal bridge formula. For each of these issues, the study committee estimated the nationwide effects of changes in federal limits proposed by the trucking industry, highway agencies, and other groups. Projections of heavy-truck miles by type of truck, region of the country, highway functional class, and operating weight were developed for a base case and alternative truck weight regulatory scenarios. These projections were then used to estimate impacts on truck costs, pavements, bridges, and safety.

Book Description
e effects of increased truck loads and higher tire pressures on performance of flexible pavements were investigated in this project. This Volume 1 report presents the research performed and the useful results obtained. Tire pressure studies were performed using both in field measurements and theoretical simulations of the effects of tire pressures on pavements. Volume 2, provides documentation for all of the computer programs developed on the project
