Certified Ready-Mix Program
MnDOT has developed the Certified Ready-Mix Program for the quality control of concrete production under a Certification program for ready-mix concrete plants.
Concrete Pavements and Rehabilitation
MnDOT's concrete paving program currently using water/cement ratio specifications. Concrete paving references include requirements for alkali silica reactivity (ASR), concrete texture specifications, historical concrete pavement data (COPES) and the concrete pavement ride information (Smoothness).
MnDOT has developed the concrete pavement rehabilitation (CPR) program using techniques that were developed in the mid-1980's and have evolved over time. Included are guidelines, CPR details and specifications.
MnDOT's new policy for sealing joints is based on the type of material below the concrete pavement. See the new Joint Sealing Recommendation Guidelines for additional information.
