This investigation of the performance of diamond grinding on jointed concrete pavements is part of a study entitled "Deter mination of Rehabilitation Techniques for Rigid Pavements," conducted between 1985 and 1988 by the University of Illinois for FHWA. The objective of the study was to improve pro
{Di d i diDiamond grinding can t d t lif extend pavement life significantly at a competitive cost. {Diamond grinding is a key Preventive Maintenance tool. {Diamond grinding will increase customer satisfaction, increase friction, reduce noise and reduce life cycle costs. .
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 ...

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.
The causes and types of failure of pavements, particularly of rigid pavements needs to be understood in order to initiate proper repair and rehabilitation programme to increase their service life. The repair and restoration of rigid pavement depends on the type of distress. Cracking is the most common feature of the rigid pavement.
