Mn/DOT Concrete Pavement Rehab Program
Concrete Pavement Rehabilitation is an extremely valuable tool to Mn/DOT in the effort to maintain our concrete pavements. The repair standards were developed in the early 1980's and revised yearly since. Great strides in technology were made in the first years, while more recently the changes have been minor as current techniques are now working well.
It is recommended that investigation into soundness of the pavement be performed before a project and specific repairs are decided upon. This investigation should include 'chaining' the pavement, coring and sometimes milling at the joints to determine severity of deterioration, and coring near and far away from the joints to test for freeze-thaw durability.
For more information about the basic types of concrete repairs and general uses and guidelines for each type of repair - Contact the Concrete Engineering Unit.
Audio-visual training aids are available by contacting the Concrete Engineering Unit at 651-366-5523.
Mn/DOT Concrete Rehabilitation Boiler Plates
**CD-HV and CX Repair Details have been revised to include 11 dowel bars per lane instead of the previously published 8 dowel bars per lane.
**Please review the revised memo to discuss changes to the details.
Changes have been made to all of the CPR details as of November 2011. The previous CPR details and the State Aid Repair Details have been modified and combined. Please review 2011 CPR Memo for details about specific changes.
The CPR Boiler Plates may be viewed either by Microstation or Adobe Acrobat. Either file includes all of the details.
