New Standards Improve Safety of Adhesive Anchor Systems
The latest of TRB's National Cooperative Highway Research Program (NCHRP) Ready Results explores test methods for adhesive anchors—bolt systems augmented by structural adhesives. Adhesive anchor systems add holding strength to steel-to-concrete connections such as concrete construction panels. However, short-term tests of fully cured adhesives do not accurately predict long-term performance.
NCHRP Report 757: Long-Term Performance of Epoxy Adhesive Anchor Systems provides a suite of testing and materials specifications, design guidelines and specifications, and construction and quality assurance guidelines. The study results were incorporated into new AASHTO specifications and formalized testing procedures that are now available to state transportation agencies to keep the public safe and prevent expensive reconstruction.
