  • RPMTAG Chapter 5 Diamond Grinding and Grooving

    Diamond grinding is one of the most cost effective concrete pavement restoration (CPR) techniques. It consists of “grinding” 3/16 to 1/4 inch (5 to 7 mm) of the surface of jointed plain concrete pavement (JPCP) using closely spaced diamond saw blades. The result is a level, smooth, and generally quieter ridingОнлайн-запрос
