NRRA: Surface Characteristics of Diamond Ground PCC Surfaces

Status:  Complete
Report Date:  07/05/2022

Summary:

NRRA States have been diamond grinding concrete pavements for many years traditionally as a preservation treatment to improve smoothness and/or enhance friction and in new construction to meet contract requirements and avoid penalties. More recently diamond grinding has used for noise reduction. NRRA States that use diamond grinding have conducted research that can add to the collective knowledge base of this process and performance. This project explores the state of practice of diamond grinding PCC surfaces and the benefits.
