    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
