This workshop will cover all aspects of rehabilitation for concrete pavements, concrete curb and gutter, and median sidewalk pavement. Specifications from the Minnesota Local Road Research Board have been incorporated into the Minnesota Department of Transportation (MnDOT) standard plates. This class will cover all the repairs, including recommendations on when to use low-volume full-depth repairs or the MnDOT high-volume full-depth repairs.

The workshop includes two field reviews: one to determine what to repair and the other to review actual concrete rehabilitation repairs constructed in 2012 on 22nd Street around Seward School in Minneapolis, including diamond grinding.
