Friction

Inclement weather - rain, snow and ice - always increases the risk of accidents and the loss of life. Automobile accidents tend to increase when there is a loss of friction between the tire and the pavement surface due to slippery conditions. Highway departments have found that the best way to decrease accidents during inclement weather is to remove water from the surface and increase the traction between the tire and the road.

The IGGA offers a variety of resources to meet this need. Below, please find case studies, technical articles, fact sheets and other resources.
