Definitions
- This invention relates to a modifier to improve the behavior of bituminous mixtures used in road paving.
- the other objective is to be able to manufacture very low thickness mixtures with high bitumen contents to avoid rapid aging and rapid fatigue depletion.
- Another of the disadvantages of the addition of fibers is that it is a heterogeneous product with respect to bitumen, which does not form mastic with it, so it is necessary to add a large amount to be effective. Additionally, and in many cases, bitumen does not adequately move the fiber so that adhesiveness problems have been detected.
- Another alternative is the use of different polymers with low melting point that are homogenized with bitumen during the manufacture of the mixture. An example of this technique can be found in European Patent Application 81 40 0820. However, this practice requires, as in the case of fibers, large amounts of polymer and long kneading times. If the kneading times are shortened, very heterogeneous and difficult to compact products are obtained.
- the third alternative is the use of previously modified bitumen with polymers.
- This widely used alternative presents the inconvenience of the need to provide the Agglomerate Manufacturing Plant with an additional deposit and keep it at a high temperature.
- the manufacture of polymer modified bitumen involves complicated and expensive installations which means an additional disadvantage.
- the object of this invention is a modifier for bituminous mixtures, which easily disperses in any proportion therein and which leads to improved properties with respect to traditional bituminous mixtures.
- One of the advantages of the modifier according to the invention is that it is presented and stored in the form of granules. Another advantage of the modifier object of this invention is that it is easily dispersed in the bituminous mixture, avoiding high dispersion times and the need to use an additional heated tank. Another advantage of the modifier according to the invention is that it does not agglomerate in the bituminous mixture during its manufacture, thereby avoiding high production times.
- the modifier according to the invention has the following advantages: when presented in the form of granules and easily dispersed in the bituminous mixture, it allows its addition in any proportion according to the need of the pavement at each application point; when dispersed easily, large heat-resistant storage tanks are not required, a mandatory practice when other modifiers are used, which translates into a much cheaper process; the use of this product implies an improvement of properties with respect to other bituminous mixtures.
- the invention provides a modifier consisting of a concentrated dispersion of a polymer in a heavy fraction from petroleum refining operations, in the presence of loads such as those used in the manufacture of bituminous mixtures for roads.
- the modifier according to the invention may contain others that suit the mixture, such as promoters of adhesiveness. These components are mixed in equipment such as those used to compose rubber.
- the invention provides a modifier for improving the performance of bituminous mixtures used in road paving, characterized in that it comprises:
- a deasphalted asphalt can be mixed with a bright stock extract to obtain a suitable product as a heavy fraction.
- the loads used in the modifier according to the invention can be any of those used in road mixes.
- One of the characteristics that these charges must have is that they are screened 100% by the 0.08 mm UNE sieve.
- the above-mentioned loads, alone or mixed together in any proportion are suitable.
- the percentage in which the mineral charge is used in the modifier according to the invention is preferably between 5 and 70%. It has been found that if the mineral load has a high percentage of pores, the dispersion of the product in the bituminous mixture is more fast
- the modifier according to the invention can include, if desired, adhesive-enhancing additives, such as those that are added to bitumen in bituminous mixtures.
- adhesive-enhancing additives such as those that are added to bitumen in bituminous mixtures.
- adhesion enhancers there may be mentioned, for example, monoammas, diammas, tnamines, amidoammas or imidazolmas, branched or not, derived from fatty acids containing at least 10 carbon atoms, alone or mixed together in any proportion .
- Non-limiting examples are the tallow diamine in which the alkylated chain has from 16 to 18 carbon atoms, the amidoamma of the resin acid and the imidazole of the resin acid.
- tall oil and rosin can be used.
- the invention provides a process for the preparation of the modifier described above which comprises adding the components of the formulation independently to the mixing equipment, or previously preparing a dry blend with all or part of the components. ingredients of the final mixture;
- the preparation of this previous dry mix can be done in any of the equipment or systems commonly used in the industry, such as paddle or propeller mixers, drums, etc.
- any of the processes or systems or mixtures normally used in the rubber industry can be used under the appropriate conditions. These processes can be continuous or discontinuous.
- the components can be added independently or from a dry mixture containing all the ingredients of the modifier in the desired concentration.
- the working temperature to be used for the preparation of the modifier can vary, depending on its composition, between 80 and 200 ° C.
- R p ocess for granulated product, the temperature range to be used may vary between 80 and 150 ° C.
- the components can be added to the extruder according to the procedure described for batch mixers.
- the addition of one or more components along the length of the extruder can also be carried out which, in certain types of mixing or relative concentrations of its components, can lead to an improvement in the quality of the composition or a greater ease of processing.
- the length / diameter (L / D) ratio of xa extruder can vary between 15 and 40 depending on whether it is single or multiple spindle, with a longer spindle interested in a single spindle to ensure the proper quality of the mixture.
- the compression ratio of the spindle can be between 1: 2 and 1: 5.
- multiple spindle extruders they will have one or more shear zones with a total length that can vary between 1 and 6 diameters depending on the composition and the other mixing conditions.
- the profile or temperatures to be used in the extruder can vary between 80 and 200 ° C.
- the procedures of cooling the cord of the extruder can be used by water bath and subsequent drying and granulation in a cutter designed for soft materials, or, preferably, the head cutting equipment can be used with which a distribution of the size of the most homogeneous pellet is obtained.
- the modifier is added to the bituminous mixture for roads at the time of manufacture.
- it can be incorporated through the "filler" addition system or by any other suitable device that has been mounted on the plants. Both the temperatures and the kneading times are the conventional ones in the preparation of these mixtures.
- the invention provides a bituminous mixture for roads incorporating the modifier described above, to impart greater cohesion to the bituminous mixture, as well as to improve the resistance to plastic deformations thereof.
- the percentage to be used of the modifier of the invention in the bituminous mixture is variable, although it is typically added to the bituminous mixture in an amount such that the percentage of polymer referred to the total bitumen of the mixture is between 1 and 10%.
- the road paving mixtures in which the modifier of the invention can be incorporated can be any hot bituminous mixture, non-limiting examples are dense, semi-dense, open, draining or discontinuous type mixtures.
- the mixture is prepared at a temperature of 100 ° C and with a spindle speed of 75 rpm.
- the extrudate obtained is cooled, dried and cut to obtain pellets.
- the first two mixtures were subjected to a deformation test ("cyclic creep test") under the following conditions:
- Test temperature 40 ° C Pressure 400 kPa
- the deformation of the mixture containing the modifier of the invention was 1.5% while the mixture containing the modified bitumen exhibited a deformation of 2.0%.
