The report includes the results of an analytical study of the effects of automobile tire loads on thin asphalt pavements over flexible bases. Two different ways of calculating the tire contact pressure were used and the strains induced in the pavement structure were evaluated. The uniform pressure tire model assumes that the tire contact pressure is equal to the tire inflation pressure. The Tielking tire model is a finite element computer program that models the tire as a shell of revolution and calculates the contact pressure distribution by using the tire carcass properties and the tire load. The results were analyzed and the findings indicate that automobile tire loads can lead to fatigue failure and rutting problems for certain combinations of surface thickness - moduli over weak bases. The best performance occurred when stiff bases were used.
