Truck Equivalency Factors, Load Spectra Modeling and Effects on Pavement Design
The objectives of this study were to develop truck factors for pavement design in Alabama and axle load distribution models for mechanistic-empirical pavement design. In addition, the effects of variations in axle load spectra obtained from different sites on pavement design requirements using both the 1993 AASHTO pavement design guide and a mechanistic-empirical (M-E) design approach were evaluated. Information from thirteen weigh-in-motion WIM sites on rural principal arterials was provided by the Alabama Department of Transportation for this study. Statistical and practical tests were used to determine the daily, monthly, directional, and site variations in truck traffic relating to the development of truck factors. A sensitivity analysis was performed to determine the effect the variation in truck factors would have on the final pavement design thickness. It was determined that using a statewide average truck factor would be sufficient for pavement design of rural principal arterials in Alabama.
