Bridge Capacity Assessment and Control of Posting, Permit and Legal Vehicle Loads

  • Fred Moses

Abstract

Several recent projects conducted by the author have concerned new methods for bridge evaluation, including strength capacity and safe life assessment. These projects have led to new AASHTO proposals for capacity evaluation and flexible methods for regulating safe loads on bridges. Economic pressure to revise truck weight regulations have also been considered. Proposals for evaluating permit trucks for different highway classifications have been reported. A comprehensive study of optimal truck weight regulations to balance vehicle productivity with increased costs for bridge repairs and replacement have been studied. These projects have been supported by the US Transportation Research Board and various state agencies.
