The synthetic resins used according to the invention have an average molecular mass of 500 to 1500 g / mol, preferably ranging from 700 to 1200 g / mol. The resin of the composition according to the invention is advantageously a so-called tackifying resin. These resins are for example hydrocarbon thermoplastic resins, that is to say mainly composed of carbon and hydrogen and optionally comprising heteroatoms such as oxygen, nitrogen or sulfur. These resins are for example obtained by copolymerization of aromatic petroleum cuts. They are clear resins, soluble in most industrial solvents and in particular in aromatic and aliphatic solvents. Preferably, these resins are neutral and devoid of functional groups. The resins of the invention are preferably chemically inert, hydrophobic and remarkably stable. The hydrocarbon resins are chosen from low molecular weight polymers which can be classified, according to the type of monomer they comprise, into indene hydrocarbon resins, aliphatic pentanediene resins, mixed pentanediene and indene resins, diene resins. dimers of cyclopentanediene, diene resins of isoprene dimers. There may also be mentioned some modified resins such as hydrogenated resins. According to a preferred embodiment, the resin is chosen from indene hydrocarbon resins. The natural resins suitable for the present invention are substances exuded by certain plants. They can be of fossil origin or so-called harvest. They can be used as they are (natural resins) or be chemically transformed. When produced by currently existing plants, they constitute renewable raw materials. Natural and natural modified harvest resins include, but are not limited to, enhanced resins, dammar, natural and modified natural rosins, rosin esters, rosin soaps, and metal resinates.

Natural rosins include gem and wood rosin and tall oil rosin, such as tall oil pitch. Among the modified natural rosins, mention may be made of hydrogenated, disproportionated, polymerized and maleicized rosins. Among the rosin esters, mention may be made of esters of glycerol and natural, hydrogenated, disproportionated, polymerized and maleicized rosin, and esters of pentaerythritol and natural and hydrogenated rosins. Among the metal resinates, mention may be made of metal carboxylates, for example Ca, Zn, Mg, Ba, Pb, Co, obtained from natural or modified rosins, calcium resinates, zinc resinates and mixed resinates of calcium and zinc. Among the fossil resins, mention may be made of copals. To usefully enter the formulation of the binder according to the invention, the resin must have a softening temperature of 100 to 200 ° C, and preferably 120 to 180 ° C.

Of course, it is possible to use mixtures of two or more natural or modified natural resins according to the invention. For more information on natural and modified natural resins, see the article by Bernard DELMOND, "Natural resins", Engineering techniques, "Physico-chemical constants" treatise - K340-1 to 12, May 2002.

In order to obtain a clear and colorable putty, the resins used according to the invention must have a Gardner color index, measured according to ISO 4630, equal to at most 8, preferably at most 6 and more preferably at most. equal to 3. The above ISO standard specifies a method for the Gardner Color Scale evaluation of the color of light yellow / brown liquid products using color measuring instruments. . The synthetic oils used in the invention consist of three main groups of molecules, paraffinic, naphthenic and aromatic molecules. The paraffinic molecules consist essentially of linear hydrocarbons, the naphthenic saturated cyclic hydrocarbon molecules and the aromatic molecules of unsaturated benzene rings. There are also molecules that contain atoms other than carbon and hydrogen, including nitrogen and oxygen. As indicated above, the binder may comprise one or more natural oils such as oils of vegetable origin. As is well known, vegetable oils are obtained by trituration of seeds, kernels, oleoginous vegetable fruits. Vegetable oils can be used raw or refined. They can also be modified by chemical reactions, such as esterification, these oils possibly being chemically modified. Among the vegetable oils that are suitable for the binder according to the invention, mention may be made of: linseed, rapeseed, sunflower, soybean, olive, palm, castor oil, wood, corn, squash, grape seed, jojoba, sesame, walnut, hazelnut, almond, shea, macadamia, cotton, alfalfa, rye, safflower, peanut and copra. Of course, the viscosity of the oil is chosen according to the resin or resins used to formulate the binder, so as to obtain a binder having the required penetrability and softening point or viscosity. The vegetable oils according to the invention may have iodine numbers of between 0 and 200. The binders formed by the mixture of the oil and the resin are preferably of grade 160/200. The solvents which can be used according to the invention are preferably esters having a melting point of between -100 and 0 ° C, preferably between -80 and -5 ° C.

The fluxing agents may be petroleum or vegetable fluxes. Preferably, fluxing agents based on fats of natural origin are used. This type of fluxing agent, also known as fluxing oil, based on animal and / or vegetable fats, makes it possible to avoid the release of volatile organic compounds (VOCs). The fluxing oil can therefore be a vegetable oil, one of its derivatives such as its fatty acid part, a mixture of fatty acids, a transesterification product or an alkyd resin derivative of the oil. However, these fluxes are often used in combination with catalysts including metal salts, although these are not recommended for the environment. It is also possible to use natural-based fat-based fluxes comprising hydrocarbon fatty chains, these naturally-occurring fats having undergone at least one chemical functionalization reaction having introduced at least one oxygenated functional group. Such fluxing agents are described in patent EP 1645 595. Preferably, the oxygen functional group introduced during the chemical modification of naturally occurring fats is chosen from the following groups: carboxylic acid, dicarboxylic acid, epoxide, peroxide, aldehyde, ether, ester, alcohol and ketone, this list not being limiting. By ether function is meant the ether ether function. Fats of natural origin are chosen from oils obtained in nature or their derivatives, fats obtained in nature or their derivatives, and mixtures thereof, for example animal and / or vegetable oils and fats. Preferentially, the vegetable oils will be used. Naturally occurring fats which will be chemically functionalized according to the invention, and therefore activated, may therefore be, without limitation, directly the oils and fats of natural origin, or fatty acids, esters of fatty acids, preferably alkyl esters, more preferably alkyl mono-esters, fatty alcohols, fatty alcohol esters, triglycerides, diacid esters, rosin acid esters, rosin acids, these compounds, and mixtures of these compounds, of animal or vegetable origin. These particular fluxes have good solvent properties at the time of mastic preparation and good reagent properties after processing so as to give the mastic its use properties, without release of volatile organic compounds. In addition, the drying power is sufficient to polymerize quickly enough without catalyst. Esterified and epoxidized tall oil derivatives and oxidized rapeseed fatty acid esters may be mentioned in particular. These fluxes are marketed under the trademark VEGEFLUX®. The elastomers that can be used according to the invention include, for example, polyesters, polyacrylates, polysulphides, polysilicones and polyester amides. Conjugated dienes such as butadiene, isoprene and block copolymers of such dienes with vinyl aromatic compounds such as styrene-butadiene may also be mentioned. An elastomer that can be used according to the present invention is a tri-block copolymer based on styrene and butadiene units marketed, for example, under the name Kraton® D-1184, Kraton® D-1116, Kraton® D-1192 and Calprene® C 401. , Calprene® C 411, Calprene® C 419, Finaprene 4118 and Europrene Sol T 6205.

When the oil and the resin are synthetic, a fatty acid salt and fatty hydroxyacid and sodium, potassium, lithium, aluminum and zinc hardener comprising from 8 to 22 carbon atoms are preferably used. carbons. The lithium or zinc salts are preferably used. For example, lithium stearate, lithium hydroxystearate, lithium palmitate and lithium hydroxypalmitate are used. The hardener can also be a wax. The waxes used in the invention may be natural or artificial waxes. In the case of natural waxes, these are derived from animal raw materials, vegetable or mineral (lignite). Artificial waxes are waxes that have undergone chemical modification. In all cases the waxes consist mainly of carbon atoms, hydrogen and oxygen. There are also some molecules containing nitrogen atoms. The waxes employed in this invention have a molecular weight of less than 10,000 g / mol.

The fillers of the invention are inert materials used as filling material. Fillers can be organic or mineral. By way of example, mention may be made of chalk, calcium carbonate, gypsum powder, talc, silica fume, fly ash and limestone. Since the mastic of the invention is stainable, any type of coloring agent can be used to color the compositions of the invention. Mention may in particular be made of inorganic pigments and organic dyes. As inorganic pigments are suitable titanium dioxide, iron oxides (ferrous and ferric), chromium oxide, copper oxide, carbon black. The mastics of the invention comprise an antioxidant preferably selected from butylated hydroxy toluene and ethoxyquin, tyrasol, oleuroprene, sesamol, propyl gallate, octyl gallate, hydrotyrasol and caffeic acid. The antioxidant may be present in a content ranging from 0.01 to 3%, preferably 0.05 to 0.5% by weight, relative to the total weight of the mastic. The cold-applied mastics also include in the solvent part A a surfactant. As surfactants, there may be mentioned polyamines such as tallow polyamines marketed under the name POLYRAM S®, tallow diamines of the Dinoram S® type, tallow monoamines of the Noram S® type of the CECA Company. The surfactant may be present in a content ranging from 0.1 to 1%, preferably 1 to 2% by weight, relative to the total weight of the sealant. The cold-applicable mastics of the invention may comprise other traditionally used additives including drying agents. These additives are preferably incorporated in Part A. The total amount of additives in Part A is preferably 5 to 10% by weight.

The cold-applicable mastics of the invention are preferably prepared in the following manner: - preparation of part A by mixing the solvent (s), elastomer (s), surfactant (s) and antioxidant (s), - preparation of Part B: - initially, the oil and the resin are mixed at a temperature of between 150 and 200 ° C., until a homogeneous mixture is obtained, and then the temperature is raised to a temperature greater than the melting temperature of the hardener used, preferably at a temperature between 210 and 230 ° C, the hardener being added to the resin oil mixture either before, during or after raising the temperature while stirring until obtained of a homogeneous mixture, then the fillers are added, preferably at a temperature between 200 and 250 ° C., the parts A and B are then mixed, preferably at a temperature of between 20 and 80 ° C.

The application of this putty is cold or hot using a putty gun or a spear, and can be done on a wet support. The invention therefore also relates to the use of cold or hot mastic for patching and / or repairing roadways or more precisely to seal cracks pavements obtained from hydrocarbon asphalt.
