-25- Abstract of the Disclosure RUMBLE STRIPS FOR HIGHWAYS The rumble strips comprise wide (5-10 cm) strips of rubber let into grooves in the road surface. The groove is out by a reflex-percussion machine (in which the cutting bit is forcibly withdrawn from the surface the instant the bit strikes the surface, so that the material flakes by induced tension). The rubber strip is wide and bulky, and provides good rumble intensity without interfering with tire passage. The rubber strip may be held in place with a shaped anchor strip, made of metal and bolted to the base of the groove. The strip may extend across the full width of a traffic lane, or may be short.
