Research for AASHTO Standing Committee on Highways. Task 319. Evaluating Applicability of the Dual-Ring Test Procedure for Assessing the Cracking Tendency of Repair Materials

The research is complete. The research included an experimental laboratory investigation to evaluate use of the dual-ring test procedure for assessing the cracking tendency of concrete repair materials. The study found the procedure suited for comparing the cracking resistance of different repair materials but not for predicting when cracking is likely to occur. A draft proposed standard test method was prepared for consideration by the American Association of State Highway and Transportation of State Highway Officials (AASHTO) Highway Subcommittee on Materials (SOM), adoption as a provisional standard test method, and inclusion in the AASHTO Standard Specifications for Transportation Materials and Methods of Sampling and Testing. The report has been provided to AASHTO staff and the proposed test method has been provided to the chair of SOM's Technical Section 3c, Hardened Concrete, for distribution and review by the members of the technical section.
