Grooving

For decades, Department of Transportation (DOT) officials have recognized the importance of grooving on bridge deck surfaces to reduce hydroplaning risks, increase water drainage and aid in vehicle control. DOTs have found the low cost invested to groove the deck offers the best return on investment for the entire project. Statistics show a clear relationship between grooved surfaces and a reduction in accidents.

The same is true for airport runways - safety is paramount. Pilots have observed that transverse grooved surfaces drastically reduce all types of skids on wet or flooded runways and provide positive nose-wheel steering during landing rollout. Grooved surfaces also prevent the onset of drift and weathervaning. Pilots find overall ground handling and stopping characteristics on grooved surfaces a dramatic improvement over ungrooved surfaces.

Whether you are searching for a roadway or airport runway solution, the IGGA offers a variety of resources to meet these needs. Below, please find case studies, technical articles, fact sheets and other resources.
