Diamond Grinding ♦ 9.1 Introduction ... Chapter 10: Rigid Pavement Rehabilitation Anchor: #i1004665 ... Compared with repair/rehabilitation of flexible pavement, rigid pavement repair/rehabilitation costs more and, if not done properly, similar distresses will develop in close proximity, and additional repair/rehabilitation will be required. ...
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. Because the grinding head is cooled with ...

Crack filling, Crack sealing, Stitching, Diamond grinding, Dowel bar retrofitting, Joint repair, Partial-depth repair and Full-depth repairs are the most common techniques used for restoration of rigid pavements. 4.2 RIGID PAVEMENT FAILURE TYPES AND CAUSES Typical rigid pavement failures and their causes are discussed in this section.
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
