Abstract

A method and apparatus for applying a traffic stripe having improved reflectivity includes 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.

Claims

1. A method for applying a night-visible traffic stripe to a road surface, said method comprising the steps of:

applying a material capable of adhesion and forming a traffic stripe to a road surface;

applying a reflective material to the traffic stripe;

applying means for preventing adhesion between the traffic stripe material and a deformation means such that the deformation means remains substantially free of traffic stripe material during a deformation step; and

deforming the traffic stripe material with the deformation means to form spaced grooves in the traffic stripe material;

wherein said step of applying means for preventing adhesion includes applying a predetermined quantity of liquid to the deformation means prior to said deforming step to cause the reflective material to adhere to the deformation means and thus form a protective coating between the deformation means and traffic stripe.

2. The method of claim 1 wherein said material applying step comprises forming a thermoplastic line by extruding the thermoplastic material from an extrusion assembly.

3. The method of claim 1 wherein said deforming the traffic stripe material step includes serially pressing projections into the material to form the spaced grooves.

4. The method of claim 1 wherein the deformation means comprises a rotatable wheel having projections with spaced grooves around the periphery thereof and said deforming step comprises passing the rotatable wheel over the traffic stripe material such that spaced grooves are formed in the traffic stripe material by pressing the projections into the traffic stripe material.

5. The method of claim 4 Wherein said applying means for preventing adhesion step comprises applying the predetermined quantity of liquid onto the rotatable wheel prior to said deforming step such that the liquid moistens the periphery of the wheel and the reflective material adheres thereto to form the protective coating.
