A road’s topmost layer, the friction layer, is literally where the rubber meets the road. The condition of this layer is important for vehicles to maintain proper traction. On high speed roadways, an open-graded friction course (OGFC) is used to reduce hydroplaning by draining water from the roadway quickly. However, this moisture can accelerate the deterioration of the friction layer in the form of raveling. Raveling is one of the leading forms of deterioration for OGFC mixtures, and is often seen as linear patches that are partially bare or potholes. These areas then have a tendency to gather water and other debris, reducing traction and potentially leading to hydroplaning.
