DEVELOPMENT OF RIGID AND FLEXIBLE PAVEMENT LOAD EQUIVALENCY FACTORS FOR VARIOUS WIDTHS OF SINGLE TIRES

An analytical study to compare the effects of axles with single and dual tires on pavement performance is presented. Both rigid and flexible pavements were analyzed using currently available finite-element and elastic-layer analysis programs. The stresses and strains obtained from these programs were used in fatigue failure models to develop equivalency relationships between dual tires and various widths of single tires. Equivalent wheel-load factors were developed for various widths of single tires on both rigid and flexible pavements. These factors can be used to evaluate regulations relating to tire and axle loadings. They also permit conversion of mixed traffic having axles with single tires to equivalent 18-kip dual-tire, single-axle load applications for use in pavement design and evaluation. (Author)
