Abstract

Diamond grinding and diamond grooving are two methods of refurbishing existing Portland cement concrete roadways. Both methods use diamond-infused steel blades to remove some of the roadway. In diamond grinding, the cutting blades are spaced close together, and the fins between the channels can break off, resulting in a rough contact patch. In diamond grooving, the blades are farther apart and the contact patch is similar to the original road surface. Using OBSI testing on the resulting roadways, it has been determined that ground and grooved surfaces can exhibit vastly different noise characteristics than the original surfaces. In this paper, the relationship between noise characteristics and properties of the refurbished surfaces is examined. It was found that the noise characteristics depend primarily on the contact patch left behind after the grinding process. By increasing the space between the blades, it was possible to reduce the roughness of the pavement and thereby decrease noise.
