Audible night-visible traffic stripe for a road and method and apparatus for making the same

Year	Description
1999	Invention patented by Forrest C. Marcato on February 11th, 1999. Abstract: A traffic stripe including a first profiled portion having improved reflectivity and a second raised portion which provides an audible indication of its presence to a driver. Also, a method and apparatus for applying the traffic stripe including a vehicle having an apparatus for applying the traffic stripe, an applying assembly for dispersing a reflective material over the traffic stripe, another applying apparatus for applying an anti-adhesion agent, and a deformation apparatus disposed rearward thereof for forming interval grooves in the traffic stripe. The application of the anti-adhesion agent directly onto the traffic stripe or onto the deformation apparatus prevents the freshly applied traffic stripe from lifting off the road surface and adhering to the deformation apparatus.
