Abstract: The disclosed coating method has the ability to satisfy some or all of the very troublesome requirements of highway marking or striping and is therefore useful to mark or stripe paved surfaces. The method involves:(a) supplying to the point of application an amine co-curative which includes an aliphatic amine (e.g. trimethyl hexamethylene diamine) and a cycloaliphatic amine (e.g. cyclohexane-bis[methylamine]);(b) supplying to the point of application a suitable curable liquid vicinal epoxide composition;(c) applying the co-curative and the liquid epoxide to the paved surface (preferably after intimately mixing the co-curative and the liquid epoxide); and(d) permitting the resulting mixture to cure in situ on the paved surface.

Abstract: A method and apparatus for marking a line, such as the centerline, along a roadway, using a vehicle carrying paint marking apparatus, in which a pair of television cameras, one mounted on each side of the vehicle, view the edges of the roadway and project the images onto a split screen. By keeping the images on the screen in a predetermined relationship the operator can steer the vehicle in a path along the roadway uniformly spaced from its edges. Preferably a third camera, centrally located on the vehicle, views the vanishing point of the roadway when straight and the image of the vanishing point is registered with a predetermined mark associated with the screen.

Abstract: Pavement striping tape is drawn through a guide mounted on a rolling machine by the direct action of the front pavement roller. The tape is delivered from a spool or spools on a first spindle mounted above the tape guide and the tape backing paper is automatically withdrawn from the tape and wound up on a spool or spools on a second spindle spaced from and rotationally powered from the first spindle. Both spindles are driven by the movement of the tape downwardly due to the direct action of the front pavement roller. The striping tape is pressed by the roller into hot fresh asphalt paving material during the final rolling of the asphalt.

Abstract: Pavement-marking sheet material made from deformable, reduced-elasticity polymeric materials are made retroreflective by adhering to the sheet material a thin support film having retroreflective elements partially embedded in it.

Abstract: A paint composition for application at elevated temperatures to form markings on roadways that bear traffic rapidly. The composition includes a paint vehicle and a modifying material dispersed in subdivided form in the paint vehicle. The modifying material is solid and substantially insoluble in the paint vehicle at normal ambient temperatures, and forms an at least substantially dissolved sprayable liquid blend with the paint vehicle at elevated temperatures. As an example, a substantially neutral polyamide reaction product of a polymerized fatty acid and polyamine is dispersed in subdivided form in a paint vehicle that comprises resin-modified drying oils dissolved in a volatile liquid.

Abstract: Coating compositions, useful for marking trafficable surfaces such as roads, are disclosed and claimed which comprise a polymer-monomer mixture and a catalyst system. The relative amounts of the components are chosen so as to provide compositions which have, surprisingly, a desirable balance of stability and fast cure.

Abstract: A distinctively and unambiguously marking of the directions of travel on motoring highways, airports and other surfaces with the aid of a thin novel saw-tooth marker strip that is adhered to the traveling surface and has distinctively colored successive surfaces of retroreflecting materials, including transverse cylindrical refractive elements embedded between wedges in the thin strip.

Abstract: Pavement markings of improved durability are obtained by first forming a bonding layer on the pavement surface with a liquid coating composition that comprises a polyamide condensation product of dimerized fatty acid and polyamine and then forming a top or marking layer over the bonding layer by applying through a flame solid particles of a marking material that comprises the same type of polyamide, preferably in a higher-molecular-weight version.

Abstract: A paint composition that rapidly congeals to traffic-bearing condition when sprayed at an elevated temperature onto a paved surface, comprising a paint vehicle and a normally solid substantially neutral polyamide reaction product dispersed in the paint vehicle, characterized in that the ingredients from which the reaction product was made include diphenolic acid.

Abstract: Ambient drying traffic paint compositions and methods for their application are disclosed comprising a resin binder and pigment(s) in a three-component or four-component solvent system, in parts by weight of:Solvent boiling point: 190-141.degree. F.; 5-11solvent boiling point: 140-106.degree. F.; 12-17solvent boiling point: 105-90.degree. F.; 2-28solvent boiling point greater than 225.degree. F; 0-12The disclosed compositions are applied at ambient temperatures without the use of external heating means and a relatively fast dry time of about 20 to 60 seconds is obtained.

Abstract: The disclosure describes a new material adapted to be laid down and adhesively secured on a road surface to provide a traffic regulating sign thereon, the material having an upper surface exposed to traffic and provided with a plurality of sharp tips projecting above said surface for imparting good non-skid properties thereto, the said new material comprising an upper layer adjacent to said upper surface, at least partially embedding hard particles to form said sharp tips and consisting of a polymeric resin having a high molecular cohesion such as a polyamide resin, a polyurethane resin or a polyterephthalic resin, thereby adding improved wear resistance properties to non-skid and high visibility properties.

Abstract: There is described a method for road surface marking with tape material, including the steps of forming an essentially bituminous primer layer on such surface and then pressingly laying a prefabricated tape material on said primer layer, such layer being formed with an essentially adhesive composition having a relatively low viscosity when contacted with the road surface and comprising a substantial percentage of cross-linkable components at least part of which is hydrophilous. The layer is capable of attaining within a few minutes a viscosity of about 10.sup.5 cp and then further hardening to provide a final resistance to horizontal stresses applied to the tape material of at least 3 kg/cm.sup.2. There also are described devices for promoting cross-linking by preforming pre-polymers of a two-component reactive composition.

Abstract: A resinous road marking composition comprising in addition to pigments and fillers a hydrocarbon resin having an average molecular weight of up to 10,000 and containing 4 to 50 per cent by weight of chemically built-in phenolic components which composition may contain an additional hydrocarbon resin being free from phenolic components. A process for preparing said composition which is pourable as a hot melt wherein the resinous binder is maintained molten at a temperature in the range from 100.degree. to 200.degree.C and a mixture of the fillers and pigments is added thereto and mixed in homogeneously.

Abstract: A method is disclosed for applying rather viscous line marking material to road surfaces whereby simultaneously with the manufacturing of marking strips in the same continuous motion crossribs from the same material are shaped on the marking strips. The marking material flows out through a slit between the back edge of the bottom side and the lower edge of the back wall of a storage box, a periodical up- and down movement being imparted to this back wall for shaping the ribs, preferably by means of fast upward driving impulses each of one followed up by a separate downward driving impulse. Preferably the material is forced to flow out substantially in a direction at an angle of at least 30.degree. to the direction of movement of the storage box and the trailing end thereof is kept in engagement with the road surface.
