Abstract:The objective of this project is to identify a representative school bus (weight and axle spacing) for load rating highway bridges. The ALDOT Bridge Rating and Load Test Section currently uses a 12.5-ton school bus (four tons on the front axle and 8.5 tons on the rear axle) as one of its seven standard bridge load-rating vehicles. However, 99% of the buses in Alabama have a gross vehicle weight rating (GVWR, provided by the bus manufacturer) greater than 13 tons and the average GVWR is 14.5 tons. This project will compile a database of axle weights and spacings for all Alabama school buses, measure axle weights and spacings of selected school buses loaded with school children, and perform bridge rating analyses on a set of critical Alabama bridges to determine a representative school bus for bridge load rating.
