Definitions

• the present invention relates to a coating material with visible hard colored charges, such as, for example, bituminous coated, resinous coated, concrete with aggregate, etc., usable in public works and building in pavement, floor coverings, of facades or other building elements, etc. It also relates to the process for manufacturing this coating material.
• colored coatings are commonly used, for example to improve road signs, to beautify the living environment, to differentiate reserved areas, tracks or lanes, for the enhancement of works, equipment or premises, etc.
• a person skilled in the art traditionally implements, for example, paving, paving and fitting of natural stones, as well as coverings composed of natural hard fillers (gravel, gravel, sand, fine, chips). stone, ...) or industrial, and a generally hydraulic agglomeration binder (concrete with visible aggregates), or hydrocarbon (bituminous mixes), or made of a resin (resinous mixes).
• agglomeration binder concrete with visible aggregates
• hydrocarbon bituminous mixes
• resin resin
• the natural or industrial aggregates can be surface-colored by the binder which agglomerates them or else, they can be colored beforehand, industrially and surface-wise, by a coating of various dyestuffs.
• This film coating is, for example, constituted in the second case, by a resin which can be freely colored with pigments which give gravel agglomerated in resinous mixes, the extreme diversity of colors which clearly distinguishes this type of coatings more commonly applied to floors. of buildings.
• the aggregates thus colored individually by a coating of pigmented resin are agglomerated by means of transparent or even colorless binders (epoxy resins, polyurethanes, methacrylates, ...) which, by transparency, highlight the coating color or colors of said aggregates.
• the originally opaque hydraulic binders In the case where the coloring of the coating is due to the binders, the originally transparent or colorless resinous binders, the originally opaque or translucent bituminous binders (so-called "clear" bitumens), are colored by pigments or fine charges. These colored binders also stain the natural or industrial aggregates which they agglomerate, and thus give their coatings their color.
• hard, natural and industrial fillers can be colored by different agglomeration binders or coating processes, and various dyeing materials, the surface colorings obtained do not durably withstand the often severe constraints of pedestrian or road sites, namely:
• agglomeration binders are commonly colored:
• the colors of hydraulic binders are deemed to be limited (to the point that concretes are often used as supports and joints for generally natural and therefore slightly colored fillers which they are asked to fix); - the colors of the coating resins and the generally colorless agglomeration resins (including those reputed to be as resistant as granite) are, depending on the types, more or less sensitive to UV, yellowing, chalking, weathering, and / or sensitive to abrasion, puncture, wear, maintenance products and processes;
• the colors of the pigmented bitumens are generally little appreciated by prescribers, reputed to be arbitrary, insufficiently varied, they impose monochrome coatings (mottled excluded) and they are more or less sensitive to UV, marking, fouling, difficult to maintain, they are also sensitive to wear and tear (the colored bitumen film, in contact with traffic, is also gradually deteriorated and eliminated) until, again, the original color of the aggregates is highlighted; in addition, the pigmentation of the bitumen also generates the major drawback of coloring all the tools or machines for production, transport, application; the pigmented bitumens being moreover incompatible with each other, they pollute each other irreparably, which requires (to pass from one color to another), costly cleaning or to specialize tools and machines according to the colors and therefore to multiply production and application lines, which translates into heavy investments; these drawbacks have the inevitable consequences of limiting the choice of colors of the coatings, and of increasing the costs thereof, without benefit for the quality of the coatings or for that of their colors.
• a coating for traffic lanes, in particular roads, cycle paths, sidewalks and pedestrian paths, car parks or parking spaces, of the bituminous binder, hydraulic or polymer type, having reinforced reflective properties is described, characterized in that it comprises 10 to 80% by weight of glass debris which contain at least 10% by weight of essentially reflective glass debris having at least one metallized or enamelled surface or containing metallic inclusions, of dimension less than 20 mm.

• the current methods of manufacturing resinous coated materials and traditional bituminous coated materials, black for example, can be directly transposed to that of colored coatings according to the invention.
• the manufactured hard fillers can advantageously consist of mass-colored glass, which can be (depending on the compositions) opaque and of stony appearance or more or less translucent.
• This aggregate of tinted glass in the mass can be constituted by crushed and / or ground glass, or even rolled (blunt), or by glass machined into aggregates with controlled shapes.
• these manufactured loads Thanks to their hardness and resistance to abrasion, scratches, wear, punctures, loads (heavy vehicles for example), these manufactured loads have properties comparable to those of natural hard loads (gravel, gravel , sands, fines) traditionally used for the production of pedestrian and road surfaces, in particular.
• these manufactured charges colored in the mass can be fixed, joined, agglomerated as and as well as natural hard charges with, for example:
• hydrocarbon binders particularly clear bitumens (but also, black or colored opaque bitumens);
• - resinous binders for example polymeric binders (polymer matrices with organomineral macromolecular skeleton, thermosets, thermoplastic elastomers) colorless, transparent or incidentally pigmented.

• prefabricated coatings made with certain fixers or binders (paving, facade panels, for example).
• colored fillers in the mass can also be obtained in controlled, predetermined, regular or irregular shapes, for example by bringing the glass to the state of a sheet more or less thick than a cylinder for example, marks , etching continuously millions of imprints to the desired shapes so that after cooling and a shock or a fall the whole disintegrates according to the contours of the imprints thus producing as many charges likely to allow the manufacture of coatings responding to specific technical and / or aesthetic requirements.

• the colored bituminous mixes according to the invention can be obtained with more or less opaque bitumens, even black for example, which can be removed on the surface of the coatings by shot peening, for example, to highlight the color or colors of the fillers on a background (or seals) of black, or even, if necessary, colored binder.
• the more the traffic will use or will eliminate more or less translucent or opaque bitumen on the surface the more the colors of the apparent charges will be highlighted, while the same constraints deteriorate the colors of the mixes traditionally colored.
• the clear bitumens which are logically the preferred binders for obtaining, according to the invention, bituminous mixes with the colors (including mottled) of the aggregates, are less costly than the pigmented clear bitumens currently used although the colors (always monochrome) of these are deemed to have the following disadvantages:
• the properties of the colored hard fillers manufactured according to the invention and the properties of the clear bitumens allow the conditioning of mixes of all colors and of different types (of different particle size compositions) in the form, for example, of bags, cans or "breads", the latter being for example molded in cylinders or in parallelepipeds with preferably a sleeve in their center to promote their rigidity and facilitate their handling. It is enough to coarsely fractionate (with a pickaxe for example) the solidified asphalt and to bring it (in a tank or a can for example) to a temperature close to that of the manufacture of the binder (generally from 40 ° to 60 ° C. ) to obtain - without any alteration in the qualities - "ready-to-use" mix, in all colors, including mottled, the latter being obtained by mixing in the desired proportions coated mixes of different colors.
• these packaging for, for example, 30 to 60 kg per unit (either one or two M 2 of coating depending on the thickness) make it possible to remedy the incapacity of bitumen power plants to produce at least less than 2 tonnes of asphalt (discontinuous) or 10 tonnes (continuous), which results in the difficulty for companies to treat punctually, with colored bituminous mixes, small or micro surfaces (signaling, pedestrian crossings, speed bumps, reserved spaces , "boats", directional islands ...), and what explains their treatment (always at risk) with paints, resins, coatings and other expensive pavings for example.
• the processes for obtaining and using coatings according to the invention have the important advantages of being identical or similar to those currently used in practice, so that the manufacture and application of these new coatings colored in the mass, do not require either a change of habits, or upgrading of the knowledge of technicians or operating personnel, or studies or special precautions for organization or implementation, or investments for adaptation or the acquisition of special materials or equipment, or the risk of consequent handling errors, or additional maintenance costs.
