Diamond grinding the surface of this concrete pavement on Wilshire Blvd. in Santa Monica, CA will extend the life of the pavement and provide a smoother, flatter, and more quiet driving surface.
Concrete Pavement Restoration (CPR) is an engineered procedure used to control the rate of deterioration in concrete pavements. In many cases, concrete pavements can be restored to extend their service life by 10 to 15 years or more. Depending on the condition of the pavement, various restoration techniques can be used including, full-depth and partial depth concrete slab repair, diamond grinding the surface, dowel bar retrofit, and resealing joints. These repairs have proven to be more cost effective than installing a thin asphalt overlay on the concrete. Managed use of CPR may be used to improve pavement smoothness, safety, friction, and quietness, in addition to the economic benefits of an extended pavement life.
Benefits of Using CPR
• Can be performed very quickly – within lane closures as short as 2 – 5 hours.
• CPR has great versatility allowing the engineers and maintenance professionals to deal with localized pavement problems with specific solutions while avoiding expenditures on good pavement.
Preserves and often improves the environmental benefits of the concrete pavement.
When implemented as a pavement management procedure, CPR can significantly extend the service life of concrete pavement with a relatively small monetary investment.
