CPR for Highway Repairs
 State Departments of Transportation across the country face a common challenge: how to repair concrete roadways that may be up to 50 years old in some locations. While replacing or overlaying deteriorated pavement can be time and cost prohibitive, Concrete Pavement Restoration (CPR) often provides the better solution.

Interstate 40CPR is a series of engineered techniques developed to manage the rate of pavement deterioration in concrete streets, highways and airports. It is a non-overlay option used to repair areas of distress in concrete pave­ment without changing its grade. This preven­tive procedure restores the pavement to a condi­tion close to or better than original and reduces the need for major and more costly repairs later. Further, CPR addresses the causes of pavement distress, minimizing further deterioration.

 

CPR techniques include:

  • Slab stabilization
  • Full-depth repairs
  • Partial-depth repairs
  • Dowel bar retrofits
  • Cross-stitching longitudinal cracks or joints
  • Diamond grinding
  • Next Generation Concrete Surface grinding
  • Joint and crack resealing
