Abstract:
With the increased use of performance-based specifications, it’s important to have acceptance tests that correlate with performance criteria. Many state departments of transportation have developed high-performance concrete mixtures to produce bridge decks with a low permeability to chloride ions. In many instances, though, prescriptive compressive strength, air content, and slump tests are used for acceptance testing. Based on the Port Authority of New York and New Jersey’s field data, the authors’ experience is that the rapid chloride permeability test (AASHTO T277 or ASTM C1202-07) is a good indicator of chloride permeability with reproducible results. By using the RCP test for mixture design and quality acceptance, it would provide concrete with the properties that are required in service.
