Diamond grinding of Portland cement concrete pavements and micromilling of bituminous asphalt pavements are superficially similar in concept but that''s just about the only thing they have in common Diamond grinding of aging Portland cement concrete PCC pavements renews the pavement''s skidresistance and provides a smootherriding
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 particles and
Diamond grinding of aging Portland cement concrete PCC pavements renews the pavement''s skidresistance and provides a smootherriding pavement And the resulting smoother profile reduces dynamic loading on the pavement thus extending its service life
