Diamond Grinding Concrete: Pavement Restoration at its Best
“Diamond grinding involves removing a thin layer (4-6 mm) at the surface of hardened cement concrete by using closely spaced diamond saw blades. The blade assembly cuts tiny grooves in the pavement surface, providing texture as it smooths down surface irregularities,” as described by the Grooving and Grinding Association.Diamond Grinding and Concrete Pavement Restoration,Although diamond grinding has been an available restoration procedure since the 1960's, recent developments and increased experience have made diamond grinding and concrete pavement restoration the best first rehabilitation option for concrete pavements. In particular, the cost competitiveness of diamond grinding has been enhanced with new, high-production equipment, and improved synthetic diamonds for saw blades. In addition, long-term performance data of diamond ground pavementsAdvantages of Diamond Grinding Concrete Pavement,,18.04.2017· Diamond grinding is a concrete pavement restoration process that renews a worn or slightly irregular surface. Diamond grinding can potentially remove or reduce some pavement deficiencies such as joint faults resulting from minor pavement settlement, worn pavement from wheel rutting, warped slabs, and a rough surface texture.RPMTAG Chapter 5 - Diamond Grinding and Grooving,Diamond grinding is one of the most cost effective concrete pavement restoration (CPR) techniques.
