Put Bridges to the Test

This article on bridges and culverts describes the best practices in evaluating concrete bridge structures. There are a number of approaches to inspection, with a range of complexity and cost. The simplest and most common is a visual inspection, a methodical, hands-on approach that looks at cracking, scaling or exposed aggregate, spalling, reinforcement, efflorescence and stains and honeycombing. Hammer sounding could also be used. Follow-up evaluations are also described, including nondestructive tests to determine underlying structural components and the integrity of the concrete. Usually, some concrete cores and powder samples are required; other invasive tests of underlying steel infrastructure are also described. Sidebar on less destructive tests is presented.
