The technical field to which the invention relates.

The present invention relates to the field of bitumen. More specifically, it relates to bituminous compositions containing the additive agent type, forming organogel, and these bituminous compositions have thermally reversible characteristics of viscosity and hardness.

The invention also relates to the use of these bituminous compositions in the field of road construction, in particular, in the production of binders for road construction, and industry. The invention also relates to a method for obtaining these bituminous compositions.

General technical information

The use of bitumen in the production of materials for road and industrial applications has long been known: bitumen is a major hydrocarbon binder used in the field of road and civil construction. That bitumen can be used as a binder in these different fields of application, it must have certain physical and chemical properties. One of the most important properties is the hardness of the bitumen, which must be sufficiently high at the temperature of application of bitumen to avoid the formation of potholes under the influence of transport. Another very important characteristic is the viscosity of the bitumen; bitumen must be sufficiently LM is Kim at the lowest possible temperature applications. Therefore, the application of bituminous binder requires a combination of hardness of bitumen at temperatures of use, and low viscosity when hot.

The level of technology

Bitumen is usually produced from residues resulting from atmospheric and/or vacuum distillation of crude oil, as well as after removal of light fractions of natural bitumen, asphalt or tar Sands. To regulate the hardness of the bitumen can be re-distilled at very high temperatures or at lower pressure to remove light fractions.

In fact, the more bitumen consists of heavy fractions, the greater the hardness. This method is not always effective enough, and heavy fractions are never completely free from light fractions.

Another way to make a more solid bitumen is its oxidation by blowing. Air blown bitumen is produced in the installation of bitumen oxidation by passing a stream of air and/or oxygen through the original bitumen. This operation can also be performed in the presence of an oxidation catalyst, such as phosphoric acid. Typically, the oxidation purge performed at high temperatures of about 200-300°C for relatively long periods of time, usually constituting from 30 minutes to 2 hours, continuously or periodically. This pic is b oxidation by blowing has a certain number of drawbacks. First, the air blown asphalts are more susceptible to aging than the original bitumen. In addition, the manufacture of blown bitumen requires special installation for the oxidation of bitumen. One of the major drawbacks blown bitumen is their viscosity, which is higher than the original bitumen at the same temperature.

Another disadvantage associated with this high viscosity, is the need for heating air blown bitumen to a higher process temperature than for oxidized bitumen of the same type, which increases the power consumption and requires additional protection for workers.

Another way to make a more solid bitumen is added polymers. The applicant company was one of the first who developed and patented the use of bitumen compositions containing polymers (FR 2376188, FR 7818534, EP 0799280, EP 0690892). These polymers make it possible, in particular, to improve the cohesion of the binder, to improve the elastic properties of the binder, to increase the range of ductility of bitumen, to increase resistance to deformation, as well as to increase the hardness of the bitumen by reducing its permeability. At the temperature of application of these characteristics, therefore, are clearly improved. However, the addition of polymers in bitumen composition at an elevated temperature generally results in an increased the structure of the viscosity of the bitumen composition. Therefore, to ensure that the bitumen can be used in the construction of the roadway, asphalt binder added polymer must be heated to a higher temperature than when using bitumen binders equivalent type without polymers. When using these polymer bitumen should be considered the same drawbacks as for the blown bitumen.

The applicant in the patent application FR 2889198 declared chemical oxidation method purge, during which the introduction of the bitumen sealing additives that increase the hardness of the bitumen at temperatures of application and limiting the increase in viscosity when hot.

Outside the scope of the invention do not go and combination of several different molecules, such as mentioned above and, in particular, molecules, described by formulas (I), (II), (III), (IV), (V), (VI) and (VII).

According to a preferred embodiment of the invention the molecules that make up organogel have a molar mass of less than or equal to 2000 g·mol-1preferably less than or equal to 1000 g·mol-1.

The temperature gap TRwhere the network of hydrogen bonds disappears depends on the number and strength of bonds formed inside agent, forming organogel, and, therefore, depends on the structure of the molecules forming organogel, and on the concentration of the agent, of forming organogel in the bitumen. The temperature gap TRin accordance with the invention is from 40°to 120°C. These temperatures were determined experimentally by measuring the softening temperature (ring and ball, as defined in the standard NF EN 1427. The correlation of these temperatures break with the disappearance of the hydrogen bonds could be accomplished using infrared spectroscopy, which allowed us to monitor the development of the intensity of absorption bands corresponding to hydrogen bonds, etc adtuyon agent, forming organogel, at different temperatures tested.

In bituminous compositions according to the invention a large portion of the bitumen and the smaller part is the agent that forms of organogel. Agent, forming organogel is from 0.1 to 5.0 wt.% relative to the weight of bitumen. Amount, less than 0.1 wt.% agent, forming organogel may be insufficient to obtain a bitumen composition according to the invention, because the molecules that make up organogel, would be too far from each other to connect together; at the same time, the number of agent forming organogel, more than 5.0 wt.%, may not be required because the agent forming organogel, operates in a small dose. For the preferred application of the agent, of forming organogel, ranges from 0.5 to 3 wt.% relative to the weight of bitumen, and even better from 1 to 2 wt.% relative to the weight of bitumen.

Bituminous compositions according to the invention may contain bitumen of different origin. First of all, we can mention the bitumen natural origin, which are found in deposits of natural bitumen, natural asphalt or tar Sands.

Bitumen according to the invention, also, are bitumens obtained by the refining of crude oil. These bitumen is produced by atmospheric and/or vacuum distillation of crude oil. Data bi which minds can, optionally, subjected to oxidation by blowing, easy cracking and/or deasphalting. Bitumen can be a bitumen hard or soft. Different obtained by purification of the bitumen can be combined with each other to achieve the best compromise solution.

Used bitumen can also be a bitumen, liquefied by the addition of volatile solvents, thinners, derived from oil, carboxylicacid the thinners and/or thinners vegetable origin.

Used bitumen can also be a special bitumens, such as bitumen, modified by the addition of polymers. As examples of polymers to bitumen mention can be made of elastomers, such as copolymers SB (copolymer of butadiene and styrene), SBS (styrene-butadiene-styrene), SIS, SBS*, SBR (styrene butadiene rubber), EPDM (ethylene-propylene mono), polychloroprene, polynorbornene and, possibly, polyolefins, such as polyethylene PE, PEHD (high density polyethylene), polypropylene PP; plastomer, such as EVA (copolymer of ethylene and vinyl acetate), EMA (copolymer of ethylene and methacrylic acid), copolymers of olefins and unsaturated esters of carboxylic acids EVE, elastomeric polyolefin copolymers, polyolefin polybutene type, copolymers of ethylene and acrylic, methacrylic acid or ester is maleic anhydride, copolymers and ternary copolymers of ethylene and glycidylmethacrylate, copolymers of ethylene and propylene rubbers, polyisobutylene, SEBS (styrene-ethylene-butadiene-styrene), ABS (Acrylonitrile-butadiene-styrene).

Other additives may also be added to the bituminous base according to the invention. They represent, for example, vulcanization agents and/or cross-linkage agents capable of interacting with the polymer when used elastomer and/or plastomer, which can be functionalized and/or may contain reactive sites.

Among agents, vulcanization may be mentioned agents based on sulfur and its derivatives, used for cross-linkage of the elastomer in amounts from 0.01% to 30% relative to the weight of the elastomer.

Among the agents of cross-linkage can be mentioned cationic agents cross-linkage, such as one - or polybasic acid or anhydrides of carboxylic acids, esters of carboxylic acids, sulfonic, sulfuric, phosphoric acid, even anhydrides of acids, phenols, which are used in quantities of from 0.01% to 30% relative to the weight of the polymer. These agents are able to interact with the elastomer and/or functionalized by blastomeres. You can use them to Supplement agents, vulcanization or instead.

There are different types of bitumen the composition is, obtained according to the invention, in particular, for the manufacture of bituminous binder, which, in turn, can be used for production combination with fillers, in particular, fillers, used in road construction. Another aspect of the invention is the use of bitumen compositions in various industries, in particular, for the manufacture of insulating lining, coating or layer impregnation.

With regard to road construction, the invention is directed, in particular, on the proposal of bituminous mixtures as materials for the establishment and maintenance of road bases and surfaces, and to perform all road works. Thus, the invention relates, for example, to the superficial layers of wear, hot mixes, cold mixtures, the mixtures are cast without heating, gravel emulsion base, a binder substance, binder layers and layers of wear and tear, as well as other combinations of bituminous binder and filler traffic coatings with special properties, such as layers, preventing coleorton, drain mixture or asphalt (mix bituminous binders and fillers of the type of sand).

As industrial applications of bituminous compositions may be mentioned the following: the production of insulating coatings, sumiso arousih coatings, insulating coatings, surface coatings, carpet tiles, layers, impregnation, etc.

The invention also relates to a method for obtaining a bituminous composition which is solid at the temperature, and its viscosity does not increase in a hot condition. Agent, forming organogel, can equally well be entered in the bitumen as such or, in the manufacturing process, the bitumen-containing polymer in the bitumen binder in a binder in anhydrous form or in the form of a bituminous mixture, but always in a hot state, at temperatures of from 140 to 180°C. Then the mixture may be stirred at this temperature until dissolution (solubilization) of the agent, of forming organogel, bitumen, polymer bitumen in the bitumen binder in a binder substance in anhydrous form or in the form of a bituminous mixture.

As the results in table 3, the correlation between the softening temperature and the temperature of disappearance of the IR bands corresponding to hydrogen bonds, for examples C6 and C4, because the temperature break is almost identical to the softening temperature.

In addition, whatever used agent, forming organogel, its effect is equivalent. It is characterized by the reduction of the permeability P25with increasing temperature (ring and ball) and povysheniya Pfeiffer. This reflects the greater hardness and density of bituminous bases with a variety of added agents forming organogel.

Similarly, the higher the concentration of the agent, of forming organogel, the greater the stiffness and density of the bitumen. A large network of hydrogen bonds increases the hardness of the bitumen at temperatures of its application.

Finally, the viscosity at a given temperature of the bitumen and bitumen with additives are equivalent. Adding agent to form organogel, allows you to make a bituminous composition harder without increasing the viscosity of the bitumen composition in a hot condition.
