Abstract
A high-friction road patch may comprise an aggregate capable of providing sufficient friction between a road surface and vehicle wheel. In some embodiments, the patch may comprise a waterproof, asphalt overlay with a first layer of cured bitumen and calcined bauxite aggregate particles, a second layer of viscous bitumen and a reinforcement component, and a binder layer for bonding the overlay with the road surface. The resulting product may provide a sufficient skid resistance value in an overlay that is far less susceptible to or incapable of debonding as with prior art solutions.
