Since then, diamond grinding has become a major element of concrete pavement restoration project in the USA. DGAG was introduced in Australia in the early 21st century. The Company has undertaken diamond grinding / grooving assignments in Australia for the past four years.


IC-QA-R93 Diamond Grinding of Concrete Pavement

produced during diamond grinding permitted. 3 . Heading title changed. 3.1 . Requirements to determine wear rate of diamond blades deleted. Statement on providing details of grinding equipment and procedures moved to clause 4.2 "Equipment". Headings added to form new sub-clauses 3.1.1 to 3.1.4.


Diamond saw cut surface textures improve pavement ...

Diamond grinding of concrete pavement leaves a surface which is often as good as a new pavement. In reducing the bumps in the pavement surface, the dynamic loading from heavy wheel loads is decreased, resulting in lower stresses in the pavement. Diamond grinding reduces road noise by providing a longitudinal texture, which is quieter than ...
