Book Description
This report presents the results of an investigation into the effect of truck tire inflation pressure and axle load on flexible and rigid pavement performance as determined using computer analysis. The flexible pavement analysis was conducted with both a nonuniform pressure model and a uniform pressure model as input to the elastic layer program BISAR and the 3D finite element program TEXGAP-3D. A rigid pavement analysis was conducted with both a nonuniform pressure model and a uniform pressure model as input to the program JSLAB.

Book Description
Current operating practice in the trucking industry related to tire pressures and truck tires are summarized. Findings of recent (since 1987) pertiment pavement performance research including both full-scale and analytical pavement response and performance studies are discussed. Pertinent findings developed in previous literature reviews are also included. Regulatory approaches developed by the various states based on information from a telephone survey conducted during July and August 1991 are included. Economic analyses are used to compare the increased annualized bituminous pavement rehabilitation costs with trucking industry benefits. Recommendations regarding the regulation of wide-base truck tires are presented.

Book Description
This study includes the results of (1) a field study to determine the tire inflation pressures currently being carried by Texas highways, (2) a literature and analytical study to determine what tire contact pressures are actually being applied by modern tires to pavements, and (3) an analytical study to evaluate the effect of those contact pressures on the stresses and strains in typical Texas flexible pavements. Descriptions of the analytical studies include discussions of the finite element computer program used to model the tire carcass and the flexible pavements. The tires included in the analytical study included both truck and passenger car tires operated at typical loads and inflation pressures.

Book Description
Dual radial tires and wide base radial single tires were tested in the laboratory under three levels of inflation pressures and axial loads. The measured characteristics of the tires were gross contact area, net area, tire deflection, and contact pressures. The distributions of contact pressures were used in a theoretical analysis to evaluate the flexible pavement performance related parameter. The response of two flexible pavement structures was investigated in terms of the tensile strains at the bottom of the asphalt layer. In the second phase of this research, two full scale pavement sections were instrumented using strain gages to measure the strains at the bottom of the asphalt concrete layer. The data analysis presented in this paper shows the effect of varying the tire type, tire inflation pressure, and axle load and configuration on the response of flexible pavements. The results of the two studies showed that the wide base single tires are more damaging than the dual tires under all combinations of the test variables.

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
