Diamond Grinding – Pavement Interactive

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 water, a byproduct of diamond grinding is a slurry of ground PCC

RPMTAG Chapter 5 - Diamond Grinding and Grooving

It is important to recognize that diamond grinding can only be used to restore some of the functional characteristics of the pavement such as smoothness and skid resistance. If the pavement has structural or material deficiencies, diamond grinding will not repair or improve any of these defects. Diamond

Grinding Diamond grinding is the removal of a thin (generally about 0.25 in. [6 mm]) layer of concrete from the surface of the con- crete pavement. Sawing is accomplished using special equip- ment outfitted with a series of closely spaced diamond saw blades. Major applications for diamond grinding are to remove surface irregularities (most commonly joint faulting or joint elevation differences ...

Repair and Rehabilitation of Rigid Concrete Pavements

Diamond grinding improves a pavement ride by creating a smooth, uniform profile by removing faulting, slab warping, studded tyre wear, and patching unevenness. It is also used for removing bumps in the newly placed concrete pavement, especially at the transverse construction joints. This extends the pavement's service life by reducing impact loadings, which can accelerate cracking and pumping.

Pavement Manual: Diamond Grinding

Diamond grinding (DG) removes a thin layer at the surface of hardened PCC pavement using closely spaced diamond blades. DG used to be an expensive operation; however, new, high-production equipment as well as improved synthetic diamonds for saw blades made DG a more cost competitive option for PCC pavement rehabilitation. DG has not been extensively used by the department as a

20/04/2019  Dowel Bar Retrofit (DBR) is a method of pavement repair that helps to re-establish a pavement’s load transfer integrity by placing steel, epoxy-coated dowels into already existing concrete across joints and cracks. The concrete is cut using a diamond-tipped blade and slots are created. Once the existing concrete has been removed, the dowels are placed in these slots, backfilled with a non-shrink grout, and the concrete is ground to ensure that the pavement
