Abstract:
Destinado a sustituir una o más de las clásicas bandas que configuran un paso de "cebra", consiste en un elemento prefabricado en el que participa un marco perimetral (1) que encierra a un núcleo plano (3), fijable mediante adhesivo a la calzada y estructurado mediante una base geotextil en la que se definen uno o más lechos (4) para implantación de mensajes informativos y/o publicitarios, establecidos mediante proyección por plasma o de tipo holográfico, que quedan cubiertos, al igual que la propia base geotextil, por una capa de poliuretano para protección de los mismos frente a los rayos ultravioleta, y opcionalmente también por una capa de poliuretano con esferas de vidrio reflectante, juntos con dispersión de carburos, para aumentar la resistencia al desgaste.
Abstract:
The invention relates to a device for additional marking of a pedestrian crossing which comprises several parallel coloured stripes. The device comprises a strip-shaped base body (1), which may be driven over and which is constructed in a saddle-roofed manner, whereby reflector bodies (8) are arranged on the front inclined face (7), for example, as an inlay in a groove (7).
Abstract:
A pavement marking tape (100) having a scrim (112), wherein the scrim is extensible to enable the tape to conform to irregularities in a road surface (116), and thereby bond more securely to that surface.
Abstract:
The invention relates to a premanufactured covering which mainly consists of a thermoplastic material and which covering is intended for roads, parking areas, etc. The covering has reflective material, friction material or the like on the intended upward surface. The covering according to the invention is characterized in that the material includes a visible temperature indicator when being applied.
Abstract:
A pavement marking and a method of making a pavement marking, where retroreflectivity and skid-resistance can be independently controlled while making efficient use of the optical elements and skid-resistant particles. One illustrative embodiment includes two topcoats (30, 32) on a base sheet (12) having first (28) and second major surfaces, the first major surface having a plurality of protuberances (14) located thereon which are separated by valleys (16). A first topcoat (30) is attached to the first major surface of the base sheet and a second topcoat (32) is selectively located on the protuberances. A first mixture of optical elements and/or skid-resistant particles (36) is attached to, e.g., partially embedded in, the first topcoat and a second mixture (34) of optical elements and/or skid-resistant particles is attached to, e.g., partially embedded in, the second topcoat.
Abstract:
A pavement marker includes a marking member (11), such as a sheet (11) or a raised pavement marker body, having an upper surface useful as a pavement marking indicium and a lower surface, and a bottom layer (14) of polyorganosiloxane pressure-sensitive adhesive in intimate contact with the lower surface. A pressure-sensitive adhesive laminate system for attaching a pavement marker to a roadway surface includes a first layer of pressure-sensitive adhesive material, such as a polyorganosiloxane adhesive, a second layer of pressure-sensitive adhesive material, and a layer of deformable material interposed between the first and second pressure-sensitive adhesive layers, wherein the deformable material of the interposed layer is characterized by high cohesive (shear) strength. A method of marking a pavement having a temperature below 15 DEG C includes providing a pavement marker of the invention and contacting the pavement with the pressure-sensitive adhesive and applying pressure to the top layer to bond the pavement marking material to the pavement.
Abstract:
A preformed thermoplastic pavement marking material composition comprising an intermix and drop-on combination of glass beads and long term skid resistance aggregate provided in the necessary proportions to achieve high skid resistance of Class S5 while maintaining high retroreflectivity of Class R5 using non-clustered regular glass beads per standard IS EN 1436. More specifically the composition particularly pertains to markers such as lines, legends, arrows, indicia, and decorative markings including pavement marking patterns utilizing thermoplastic sheeting which utilize an adhesive (sprayable or otherwise) to maintain the integrity of the pattern prior to and during its application to a substrate.
Abstract:
Vialeta de senalizacion en carreteras formada por una base de soporte (2) fijada al asfalto en su parte inferior y una carcasa superior (1) con cristales reflectantes (5) en sus caras laterales acopladas entre si a traves de unas guias verticales (12) en la superficie superior de la base de soporte (2) que se corresponden con unas protuberancias verticales (7) en la parte inferior de la carcasa superior (1). En la base de soporte (2) en su superficie inferior hay unos canales de sujecion (8) al asfalto con paredes angulares laterales que recorren todo la vialeta de un lado al otro.
Abstract:
The present application generally relates to a thermoplastic road marker having improved crack-resistance, to compositions of such road markers, and to methods of making and applying these road markers. Some embodiments of the present disclosure relate to a thermoplastic road marking composition, comprising: ethylene vinyl acetate ("EVA") and/or ethylene acrylic acid ("EAA") copolymers in an amount of between about 1.5 wt% to about 6.0 wt%; and core-shell particles in an amount of between about 0.5 wt% and about 3.0 wt%. In at least some embodiments, the EVA and/or EAA have a melt flow index equal to or less than 45 g/ 10 min at 190o? C.
Abstract:
This invention concerns a pre-fabricated marking system and a method for producing such a marking system, comprising the steps of a) producing a base layer (4) made of a first meltable composition whereby said first meltable composition comprises a material selected from the group consisting of resin, polymer, filler, softener and plasticizer, b) cooling the so produced base layer (4), c) applicating at least one, wholly or partly covering layer (5) onto the base layer (4) of one or more different second meltable composition(s) whereby said second meltable composition comprises a material selected from the group consisting of resin, polymer, plasticizer and preferably one or more pigments (2,3), and d) solidifying at least the base layer (4).
