Abstract
Abstract A pressure regulating marking on a roadway area is formed by applying onto a surface area a traffic-wear resistant layer having a small thickness and constituted by a pigmented resin material, providing a plurality of retroreflective globules having a minimum dimension which is many times greater than the thickness of the traffic-wear resistant layer, wetting the globules by a wetting resin material which is compatible with the pigmented resin material of the traffic-wear resistant material, and applying the globules which are wetted by the wetting resin material, onto the traffic-wear resistant layer, so that the wetting resin material forms, in the region of each of the globules a collar which firmly connects each globule to the traffic-wear resistant layer.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
191 words
A method of forming a traffic regulating marking on a roadway area, comprising the steps of forming a traffic wear resistant later on a surface of a roadway area, which layer has a predetermined thickness and is constituted by a pigmented resin material, said traffic wear resistant layer having an outer face; providing a plurality of retroreflective globules having a minimum dimension which is a multiple of the thickness of said traffic wear resistant layer and an elongated major dimension; wetting said globules by a wetting resin material which is compatible with said pigmented resin material of said traffic wear resistant layer; and applying the globules which are wetted by said wetting resin material, onto said outer face of said traffic wear resistant layer, so that the elongated major dimensions of said globules wetted by said wetting resins are in contact with but not embedded in said outer face of said traffic wear resistant layer, and said wetting resin material forms, on said outer face in the region of each of said globules, a separate collar which individually connects each globule to said outer face of said traffic wear resistant layer.
Claim 2
Independent Claim
191 words
A method of forming a traffic regulating marking on a roadway area, comprising the steps of forming a traffic wear resistant later on a surface of a roadway area, which layer has a predetermined thickness and is constituted by a pigmented resin material, said traffic wear resistant layer having an outer face; providing a plurality of retroreflective globules having a minimum dimension which is a multiple of the thickness of said traffic wear resistant layer and an elongated major dimension; wetting said globules by a wetting resin material which is compatible with said pigmented resin material of said traffic wear resistant layer; and applying the globules which are wetted by said wetting resin material, onto said outer face of said traffic wear resistant layer, so that the elongated major dimensions of said globules wetted by said wetting resins are in contact with but not embedded in said outer face of said traffic wear resistant layer, and said wetting resin material forms, on said outer face in the region of each of said globules, a separate collar which individually connects each globule to said outer face of said traffic wear resistant layer.
Claim 3
Dependent Claim
21 words
The method of claim 1, wherein the thickness of said traffic wear resistant layer is not greater than one half millimeter.
Claim 4
Dependent Claim
17 words
The method of claim 1, wherein the minimum dimension of said globules is greater than one millimeter.
Claim 5
Dependent Claim
15 words
The method of claim 1, wherein said globules are asymmetrical in a vertical sectional plane.
Claim 6
Dependent Claim
16 words
The method of claim 4, wherein said globules are elongated in the direction of light impingement.
Claim 7
Dependent Claim
26 words
The method of claim 1, wherein said wetting resin is identical to said pigmented resin material and is differentiated therefrom by a higher degree of catalyzation.
Claim 8
Dependent Claim
52 words
The method of claim 1; and further comprising the steps of providing a fiber reinforced base layer, said forming step including placing said traffic wear resistant layer onto said base layer so as to form a prefabricated tape material and applying said prefabricated tape material onto the surface of the roadway area.
Claim 9
Dependent Claim
26 words
The method of claim 1, wherein the said traffic wear resisting layer is a fiber reinforced base layer which is impregnated with a wear resistant resin.
Claim 10
Dependent Claim
38 words
The method of claim 1, wherein said pigmented resin material is hardenable, said globules wetted by said wetting resin being applied onto said traffic wear resistant layer when said pigmented resin material of said layer is not hardened.
Claim 11
Dependent Claim
192 words
A roadway area, comprising a pavement forming an area surface; and a traffic regulating marking including a traffic wear resistant layer secured to said surface and having an outer face, said traffic wear resistant layer having a predetermined thickness and being constituted by a hardenable pigmented material, a plurality of retroreflective globules contacting and upwardly protruding from said outer face of said traffic wear resistant layer, said retroreflective globules having a minimum dimension which is a multiple of the thickness of said traffic wear resistant layer and an elongated major dimension, said retroreflective globules being applied on said outer face of said traffic wear resistant layer so that the elongated dimension of said retroreflective globules are in contact with but not embedded in said outer face of said traffic wear resistant layer, and a wetting resin material which wets said globules before applying onto said outer face of said traffic wear resistant layer and forms a plurality of separate collars each extending upwardly from said outer face of said traffic wear resistant layer and individually connecting a respective one of said globules with said outer face of said traffic wear resistant layer.
Claim 12
Dependent Claim
192 words
A roadway area, comprising a pavement forming an area surface; and a traffic regulating marking including a traffic wear resistant layer secured to said surface and having an outer face, said traffic wear resistant layer having a predetermined thickness and being constituted by a hardenable pigmented material, a plurality of retroreflective globules contacting and upwardly protruding from said outer face of said traffic wear resistant layer, said retroreflective globules having a minimum dimension which is a multiple of the thickness of said traffic wear resistant layer and an elongated major dimension, said retroreflective globules being applied on said outer face of said traffic wear resistant layer so that the elongated dimension of said retroreflective globules are in contact with but not embedded in said outer face of said traffic wear resistant layer, and a wetting resin material which wets said globules before applying onto said outer face of said traffic wear resistant layer and forms a plurality of separate collars each extending upwardly from said outer face of said traffic wear resistant layer and individually connecting a respective one of said globules with said outer face of said traffic wear resistant layer.

Claim 16
Dependent Claim
17 words
The roadway area of claim 1, wherein said globules are elongated in the direction of light impingement.
