#aAlso available online. 530 #aFinal report;#bSep. 1982-Aug. 1986. 513 #aIn cooperation with the Department of Transportation, Federal Highway Administration. 500 #bResearch study number 2-8-83-372. 536 #aThis 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. The field study showed that tire inflation pressures are much higher on the road than those typically used in design procedures or even in analysis. Truck tire pressures average between 95 and 100 psi on the road and 75-80 psi typically used in design. However, these high truck tire inflation pressures translate to contact pressures in the range of 150 to 200 psi. The effect of these high contact studies show that, for pavements typical of the Texas Farm to Market System, the thin, flexible surfaces or thick stiff surfaces offer the best protection against these high contact pressures.
