About IGGA The International Grooving & Grinding Association (IGGA) is a non- profit trade association founded in 1972 by a group of dedicated industry professionals committed to the development of the diamond grinding and grooving process for surfaces constructed with Portland cement concrete and asphalt. In 1995, the IGGA joined in affiliation with the American Concrete Pavement Association (ACPA) to form today what is known as the IGGA/ACPAConcrete Pavement Preservation Partner- ship (IGGA/ACPACP3). Today this partnership serves as the technical resource and industry leader in the marketing of optimized pavement surfaces, concrete pavement restoration and pavement preservation around the world. The mission of the IGGA is to serve as the leading technical and promotional resource for the acceptance and proper use of diamond grinding and grooving as well as PCC preservation and restoration.

noise SMA10 pavement,” said Yvonne Bowles, Senior Project Man- ager, Roads and Maritime Services. “This now provides opportunities to integrate the surfacing treatment into future infrastructure where it meets the project requirements and we will continue to work with the industry to ensure learnings are captured and ongoing development of the treatments is undertaken.” “The results of the low-noise diamond grinding trial on the Nambucca Heads to Urunga project are consistent with the former trial on the Hunter Expressway undertaken in 2014. Not only is the noise result equivalent to the asphalt surface, it is likely to have better acoustic durability. NSW road noise policy has been updated to include NGCS, called LNDG in Australia, and our policy documents are evolving to recognize improved surfacing techniques with more emphasis on the whole of life performance,” said Peter Carson, Senior Project Manager, Roads and Maritime Services. “The IGGA and its members have been working with Australian trans- portation authorities to incorporate CDG and other diamond saw cut textures into the RMS tool box since the year 2000, with great success,” said John Roberts, executive director of the IGGA. “The successful roll out of the NGCS further exemplifies the versatility and cost effective- ness of diamond saw cut textures when transportation specifiers are faced with the unique challenges of this modern era.”
