Abstract:

In this report, nondestructive test (NDT) methods are evaluated in the context of providing input parameters to perform bridge load rating calculations for different bridge types. Relevant NDT methods are identified based on diverse technologies including mechanical impact, acoustic, electromagnetic, electrical and chemical, cuclear, and miscellaneous methods. The required parameters for successful bridge load rating of concrete precast slab (COPCSS), concrete slab (COSLAB), concrete prestress channel (COPSCH), prestressed girder bridges, and steel bridges are identified and the available NDT methods to provide these parameters are presented. These parameters are categorized in three basic groups that consist of as-built geometric parameters, as-built strength parameters, and as-inspected strength parameters. All the available NDT techniques that can be used to obtain each parameter have been presented. Finally, the NDT methods are rated by cost, ease of use, and reliability of data using a three-level rating system and the most cost effective, feasible, and reliable methods have been recommended.
