Abstract:
This summary report presents results from a study that established a relationship between truckload spectra and bridge service life at the national, regional, and State levels. Weigh-in-motion data and bridge inspection data were obtained nationwide from the Long-Term Pavement Performance (LTPP) and Long-Term Bridge Performance Programs (LTBP), respectively. The study used weigh-in-motion data to obtain various truck-loading statistics for all trucks fleet weights, overweight trucks fleet weights, single-axle weights, tandem weights, and tridem-axle weights.
