Next Generation Concrete Surface (NGCS) refers to a concrete surface designed to reduce noise levels without tires losing their grip on the road surface. NGCS uses a combination of diamond grinding and grooving on the concrete surface to achieve this.

The NGCS is a long-lasting, economical, noise reducing surface developed for concrete pavement. These diamond saw-cut surfaces are designed to provide a consistent profile absent of positive or upward texture. Since the NGCS is a “manufactured” surface, it is more consistent and predictable than most traditional surfaces.

The NGCS surface was developed through a partnership consisting of the IGGA, American Concrete Pavement Association (ACPA), Portland Cement Association and Purdue University. Extensive field testing and evaluation were conducted by Mn/DOT at the MnROAD pavement research facility.
