Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
164 words
An elongated, prefabricated, composite, self-adhesive roadway warning device for transverse attachment to a roadway surface, said device comprising: an elongated pavement mixture layer having a first side and an opposite second side, said first side defining an exposed warning surface, an elongated intermediate layer having a first side and an opposite second side, said first side of said intermediate layer being attached to and substantially covering said second side of said pavement mixture layer, an adhesive layer having a first side and an opposite second side, said first side of said adhesive layer being attached to and substantially covering said second side of said intermediate layer, said second side of said adhesive layer adapted to adhere to the roadway surface, and removable covering means attached to said second side of said adhesive layer, wherein said warning surface protrudes from the roadway surface across which said warning device is transversely adhered, said protruding warning surface being adapted to jar vehicles driven over said warning device.
Claim 2
Dependent Claim
164 words
An elongated, prefabricated, composite, self-adhesive roadway warning device for transverse attachment to a roadway surface, said device comprising: an elongated pavement mixture layer having a first side and an opposite second side, said first side defining an exposed warning surface, an elongated intermediate layer having a first side and an opposite second side, said first side of said intermediate layer being attached to and substantially covering said second side of said pavement mixture layer, an adhesive layer having a first side and an opposite second side, said first side of said adhesive layer being attached to and substantially covering said second side of said intermediate layer, said second side of said adhesive layer adapted to adhere to the roadway surface, and removable covering means attached to said second side of said adhesive layer, wherein said warning surface protrudes from the roadway surface across which said warning device is transversely adhered, said protruding warning surface being adapted to jar vehicles driven over said warning device.
Claim 3
Dependent Claim
36 words
The elongated warning device according to claim 1 wherein said second side of said adhesive layer is adapted to be attached to said first side of said pavement mixture layer of a second substantially identical device.
Claim 4
Dependent Claim
67 words
The elongated warning device of claim 1 wherein the shape of said first and second sides of said pavement mixture layer is substantially rectangular, the shape of said first and second sides of said intermediate layer is substantially rectangular, and said pavement mixture layer and intermediate layer each having first and second elongated opposite edges and first and second opposite ends substantially perpendicular to said opposite edges.
Claim 5
Dependent Claim
17 words
The elongated warning device of claims 1 or 3 wherein said intermediate layer is formed from mesh.
Claim 6
Dependent Claim
14 words
The elongated warning device of claim 4 wherein said mesh is formed from plastic.
Claim 7
Dependent Claim
14 words
The elongated warning device of claim 4 wherein said mesh is formed from metal.
Claim 8
Dependent Claim
39 words
The elongated warning device of claim 3 wherein the distance between said first and second sides of said pavement mixture layer is less than the distance between said opposite elongated first and second edges of said pavement mixture layer.
Claim 9
Dependent Claim
29 words
The elongated warning device of claim 3 further comprising means for longitudinally annexing one warning device to another substantially similar warning device to provide a longitudinally extended warning device.
Claim 10
Dependent Claim
74 words
The elongated warning device of claim 8 wherein said first end of said pavement mixture layer has a groove portion and said second end of said pavement mixture layer has a tongue portion, said tongue portion being adapted to mate and engage with a groove portion of a second substantially identical warning device and said groove portion being adapted to mate and engage with a tongue portion of a third substantially identical warning device.
