Abstract:
Structural crack repairs should be specified by using performance specifications. They are less likely to limit competition in bidding repair work when compared to proprietary or descriptive specifications. However, in order to use performance specifications, and adequate quality assurance test is needed. A laboratory test program was conducted to determine an acceptance criterion which would facilitate the use of performance specifications. The test results indicate that acceptance based on repaired strength can lead to rejecting adequate repairs. A mode of failure criterion is proposed and would provide specifiers the quality assurance test needed.
