AASHTO RAC MEMBER SURVEY RESULTS


Bending Requirements for Steel Bars for Concrete Reinforcement

10/25/18

The Wisconsin Department of Transportation’s Bureau of Structures is gathering information regarding other states' experiences with, and policies on, high strength bar steel reinforcement quality assurance bend testing (per ASTM/AASHTO: “The bend-test specimen shall withstand being bent around a pin without cracking on the outside radius of the bent portion…”).
Please forward this survey to your agency's State Bridge Engineer.

1. Does your agency perform quality assurance bend testing, or does it rely on a manufacturer’s certificate of compliance?

2. Which standard for steel reinforcement does your state specify? (e.g., AASHTO M31 Grade 60, ASTM A615 Grade 60, or ASTM A706 Grade 60)

3. What issues, if any, has your agency experienced with meeting bend test requirements?

4. What strategies has your state employed to overcome these issues?

5. Provide attachments or links to any relevant policies or other materials.
