Concrete anchorages - threaded rod applications

Products listed in the following table are approved for use on MnDOT projects unless otherwise indicated.  Products prohibited from use in sustained tension applications may be used for applications which are not considered to carry sustained tension loads.  Adhesives permitted for use with sustained tension applications may be used for all applications (sustained or non-sustained tension).  All bar types and hole types marked with “X” below are approved for use under the conditions stated in the table.  All anchorages must be field tested as required by the contract regardless of nominal pullout requirements.  Refer to project specifications and plans to determine if the anchors are in sustained tension.

Permitted sustained tension applications will be specified in an upcoming technical memorandum.  Until publication of the memorandum, please contact Joe Black for permitted uses of anchorages in sustained tension.
