For concrete pavements in good structural condition, diamond grinding can be a highly effective and economical rehabilitation alternative. The history of continuous diamond grinding for pavement restoration dates back to 1965, to a 19-year-old section of the San Bernardino Freeway (I-10) in California that was diamond-ground to eliminate excessive faulting.

Diamond grinding is a concrete pavement restoration process that renews a worn or slightly irregular surface. Diamond grinding can potentially remove or reduce some pavement deficiencies such as joint faults resulting from minor pavement settlement, worn pavement from wheel rutting, warped slabs, and a rough surface texture.
