Last year the International Grooving & Grinding Association (IGGA) announced construction of diamond grinding and grooving test sections at Virginia Tech Transportation Institute (VTTI) Smart Road research facility.
These test sections were constructed to facilitate future road research by VTTI and others. In January 2011, Safety Grooving and Grinding constructed three test strips situated on two test areas. The three test strips included a conventionally diamond ground (CDG) section and an area that was both CDG followed by longitudinal grooving of each half of the lane using two different groove spacings; ½ and ¾ in.. Each of the two test areas were ground one lane wide and 528 feet long.
