Concrete Repair

eCPR refers to a series of repair techniques used to bring the structural capacity or rideability of a deteriorating concrete pavement to an acceptable condition. CPR techniques each have a unique purpose to repair or replace a particular distress (kind of deterioration) found in concrete pavement, or to prevent or slow further deterioration. The seven most common CPR techniques are:

  • Slab stabilization
  • Full-depth repair
  • Partial-depth repair
  • Retrofitting dowels
  • Cross-stitching longitudinally-oriented cracks or longitudinal joints
  • Diamond grinding
  • Joint & crack resealing

Learn more about each technique at at the International Grooving & Grinding website.
Here’s an interesting article by Kristin Dispenza (IGGA) that was published in Roads & Bridges, February 2020, entitled “Is Slurry An Ugly Word?”
