Publication Details Concrete Pavement Rehabilitation Guide for Diamond Grinding . Primary Topic: Pavement Rehabilitation. Description: Document briefly summarizes diamond grinding technique for rigid pavement restoration and discusses the concept, equipment, advantages, design considerations, construction, performance and document also provides an example guide specification.
Diamond Grinding – PCC Pavements. Although typically used for rigid pavement surface restoration, diamond grinding can be used to eliminate relatively small surface distortions in existing rigid pavement prior to flexible or rigid overlays. Because it roughens the existing rigid pavement surface, diamond grinding also improves the bond ...
Diamond grinding is a concrete pavement restoration technique that corrects irregularities such as faulting and roughness on concrete pavements. Diamond grinding should be used in conjunction with other Concrete Pavement Rehabilitation (CPR) techniques. A full CPR job can restore structural and functional capacity of a pavement to acceptable levels

Diamond grinding addresses serviceability problems but not their root cause. For example, diamond grinding can substantially reduce the roughness on a faulted rigid pavement, but it will not address the cause of faulting, nor will it prevent roughness in the future as a result of additional faulting.

Diamond grinding is a procedure used to restore or improve pavement ride quality and surface texture. Although diamond grinding has been an available restoration procedure since the 1960''s, recent developments and increased experience have made diamond grinding and concrete pavement restoration the best first rehabilitation option for concrete pavements.
