Diamond grinding was first used in California, in 1965 on a 19-year-old section of I-10, to eliminate significant faulting. Since this first application, pavement grinding has grown to become a major element of PCC (Portland Cement Concrete) pavement restoration. The procedure is also used to insure a smooth ride on a newly constructed pavement.
