Los procedimientos para la preparacion de asfalto se basan en el calentamiento de material de roca, el denominado material blanco, asi como la adicion mediante mezcla de aditivos. Por el documento DE 40 35 050 C2 se conoce un procedimiento para la preparacion de mezclas de asfalto, transportandose una mezcla calentada de una fabrica de asfalto a una fabrica de satelites y mezclandose ahi con asfalto derretido hasta dar una mezcla de asfalto. Por el documento EP 0 641 886 A2 se conoce un tambor de preparacion para calentar material de roca y asfalto recuperado granulado, pudiendo calentarse con el tambor de preparacion de manera sencilla y economica una gran cantidad de asfalto recuperado granulado y pudiendo anadirse al nuevo material de roca. Se conocen otros procedimientos y dispositivos para la preparacion de asfalto por los documentos WO 2007/103345 A2, US 6.196.710 B1, US 4.867.572 y US 4.600.379 A.The procedures for the preparation of asphalt are based on the heating of rock material, the so-called white material, as well as the addition by mixing additives. From DE 40 35 050 C2 a process for preparing asphalt mixtures is known, a heated mixture being transported from an asphalt factory to a satellite factory and mixing there with melted asphalt until a mixture of asphalt is given. From EP 0 641 886 A2 a preparation drum for heating granulated recovered rock and asphalt material is known, a large amount of granulated recovered asphalt can be heated with the preparation drum in a simple and economical manner and being able to add to the new material of rock. Other procedures and devices for the preparation of asphalt are known from WO 2007/103345 A2, US 6,196,710 B1, US 4,867,572 and US 4,600,379 A.
El documento WO 2007/103345 A2 desvela un procedimiento con las caracteristicas del preambulo de la reivindicacion 1.WO 2007/103345 A2 discloses a process with the characteristics of the preamble of claim 1.
La invencion tiene por objetivo crear un procedimiento para la preparacion de asfalto, impidiendose que se pegue el granulado de asfalto reciclado de grano fino.The invention aims to create a process for the preparation of asphalt, preventing the graining of recycled fine grain asphalt from sticking.
El objetivo se consigue mediante las caracteristicas de la reivindicacion 1. El foco de la invencion consiste, en un procedimiento para la preparacion de asfalto mediante un procesamiento adicional de material blanco y granulado de asfalto reciclado, la incorporacion al granulado de asfalto reciclado de una carga antes de alcanzar una estacion de procesamiento adicional. Como estaciones de procesamiento adicional pueden servir un tambor de secado, un tambor de secado de granulado, una mezcladora o un elevador caliente. Como carga se usa preferentemente polvo, que mediante adhesion transforma un granulado de asfalto pegajoso en una superficie de material relativamente seca y susceptible de corrimiento. Este efecto se denomina tambien el denominado efecto de empanado. La carga usada para ello esta presente como producto de una eliminacion de polvo, que forma parte integrante de una instalacion de mezcla de asfalto, agrupandose la carga debido a su tamano de particula en carga gruesa y carga fina. Ademas, la carga puede usarse tambien como producto fabricado externamente para incorporar al granulado de asfalto reciclado.The objective is achieved by means of the characteristics of claim 1. The focus of the invention consists in a process for the preparation of asphalt by means of an additional processing of white material and granules of recycled asphalt, the incorporation into the recycled asphalt granulate of a load before reaching an additional processing station. As additional processing stations, a drying drum, a granulate drying drum, a mixer or a hot elevator can be used. As a load, powder is preferably used, which by adhesion transforms a sticky asphalt granulate into a surface of relatively dry and susceptible material. This effect is also called the breading effect. The load used for this is present as a product of a dust removal, which is an integral part of an asphalt mixing installation, the load being grouped due to its size of particle in coarse load and fine load. In addition, the cargo can also be used as an externally manufactured product to incorporate into the recycled asphalt granulate.
De las reivindicaciones dependientes se desprenden otras configuraciones ventajosas de las invenciones.The dependent claims show other advantageous configurations of the inventions.

A continuation se describe con referencia a la Figura 2 un segundo ejemplo de realizacion de la invencion. Las partes identicas desde el punto de vista constructivo obtienen las mismas referencias que en el primer ejemplo de realizacion, a cuya descripcion se remite en el presente documento. La diferencia esencial con respecto al primer ejemplo de realizacion consiste en que una cinta de adicion 12 esta dispuesta en una zona central del tambor de secado 4. Ademas, el silo de polvo 11 esta unido a traves del sinfin de tubo 5, un elevador de carga 13 y un anillo de adicion 14 con el tambor de secado 4. A diferencia del primer ejemplo de realizacion, la carga 3 se suministra a traves del sinfin de tubo 5 y el elevador de carga 13 al granulado de asfalto reciclado 2. El granulado de asfalto reciclado 2 al que seA second example of embodiment of the invention is described below with reference to Figure 2. Identical parts from the constructive point of view obtain the same references as in the first embodiment, to which description is referred to herein. The essential difference with respect to the first embodiment is that an addition belt 12 is arranged in a central zone of the drying drum 4. In addition, the powder silo 11 is connected through the tube auger 5, a booster load 13 and an addition ring 14 with the drying drum 4. Unlike the first embodiment, the load 3 is supplied through the tube auger 5 and the load elevator 13 to the recycled asphalt granulate 2. The granulate of recycled asphalt 2 to which

ha incorporado la carga 3 se transporta a traves de, y a traves del anillo de adicion 14 hacia el tambor de secado 4. Ahi se efectua un calentamiento y una mezcla continuos del material blanco 8 y del granulado de asfalto reciclado 2 en el tambor de secado 4. A continuacion se transporta adicionalmente esta masa calentada mezclada hacia el elevador caliente 10.It has incorporated the load 3 is transported through, and through the addition ring 14 towards the drying drum 4. There a continuous heating and mixing of the white material 8 and the recycled asphalt granulate 2 is carried out in the drying drum 4. Next, this mixed heated mass is further transported to the hot elevator 10.
A continuacion se describe con referencia a la Figura 3 un tercer ejemplo de realizacion de la invencion. Las partes identicas desde el punto de vista constructivo obtienen las mismas referencias que en los dos primeros ejemplos de realizacion, a cuya descripcion se remite en el presente documento. La diferencia esencial con respecto a los primeros dos ejemplos de realizacion consiste en que la cinta de adicion 12 esta unida directamente con un elevador de granulado de asfalto reciclado 16, a cuya salida se conecta un tambor de secado de granulado 15. El tambor de secado de granulado 15 esta dispuesto de manera adicional al tambor de secado 4 en la instalacion 1 y se denomina tambien tambor paralelo. Al granulado de asfalto reciclado 2 se le incorpora la carga 3 a traves del sinfin de tubo 5 y se suministra a traves de la cinta de adicion 12 y el elevador de granulado de asfalto reciclado 16 al tambor de secado de granulado 15. El calentamiento continuo del material blanco 8 se efectua en el tambor de secado 4, el calentamiento continuo del granulado de asfalto reciclado 2 en el tambor de secado de granulado 15. Al contrario que el suministro del material blanco 8 hacia el tambor de secado 4, en el tambor de secado de granulado 15 se efectua la adicion del granulado de asfalto reciclado 2 no en el punto que presenta la distancia mas grande con respecto a un quemador del tambor de secado de granulado 15, sino en el punto en el que el quemador del tambor de secado de granulado 15 esta instalado. La razon de ello es una probabilidad relativamente mayor de una ignicion del granulado de asfalto reciclado 2 frente a la del material blanco 8, de modo que el granulado de asfalto reciclado 2 entra en contacto con el quemador del tambor de secado de granulado 15 en un estado de partida frio y humedo y no en un estado secado.A third example of embodiment of the invention is described below with reference to Figure 3. Identical parts from the constructive point of view obtain the same references as in the first two examples of realization, the description of which is referred to herein. The essential difference with respect to the first two embodiments is that the addition tape 12 is directly connected with a recycled asphalt granulator elevator 16, at which outlet a granulate drying drum 15 is connected. The drying drum of granulate 15 is additionally arranged to the drying drum 4 in installation 1 and is also called a parallel drum. The load 3 is incorporated into the recycled asphalt granulate through the tube auger 5 and is supplied through the addition tape 12 and the recycled asphalt granule elevator 16 to the granulate drying drum 15. Continuous heating of the white material 8 is carried out in the drying drum 4, the continuous heating of the recycled asphalt granulate 2 in the granulating drying drum 15. Unlike the supply of the white material 8 to the drying drum 4, in the drum of granulating drying 15 the recycled asphalt granulate 2 is added not at the point with the greatest distance with respect to a burner of the granulating drying drum 15, but at the point where the burner of the drum of granulate drying 15 is installed. The reason for this is a relatively greater probability of an ignition of the recycled asphalt granulate 2 versus that of the white material 8, so that the recycled asphalt granulate 2 comes into contact with the granulate drying drum burner 15 in a cold and wet starting state and not in a dried state.
A continuacion se describe con referencia a la Figura 4 un cuarto ejemplo de realizacion de la invencion. Las partes identicas desde el punto de vista constructivo obtienen las mismas referencias que en los primeros tres ejemplos de realizacion, a cuya descripcion se remite en el presente documento. La diferencia esencial con respecto a los primeros tres ejemplos de realizacion consiste en que el granulado de asfalto reciclado 2 sin previo calentamiento en el tambor de secado 4 o el tambor de secado de granulado 15 se suministra en un estado de partida frio y humedo al material blanco 8 secado directamente en el elevador caliente 10 y ahi se calienta de manera continua y se seca. La incorporacion al granulado de asfalto reciclado 2 de la carga 3 se efectua a traves del sinfin de tubo 5 directamente antes del suministro del granulado de asfalto reciclado 2 hacia el elevador caliente 10.A fourth example of embodiment of the invention is described below with reference to Figure 4. Identical parts from the constructive point of view obtain the same references as in the first three examples of realization, the description of which is referred to herein. The essential difference with respect to the first three exemplary embodiments is that the recycled asphalt granulate 2 without prior heating in the drying drum 4 or the granulating drying drum 15 is supplied in a cold and wet state to the material white 8 dried directly in the hot elevator 10 and there it is continuously heated and dried. The incorporation into the recycled asphalt granulate 2 of the load 3 is carried out through the tube auger 5 directly before the supply of the recycled asphalt granulate 2 to the hot elevator 10.
A continuacion se describe con referencia a la Figura 5 un quinto ejemplo de realizacion de la invencion. Las partes identicas desde el punto de vista constructivo obtienen las mismas referencias que en los primeros cuatro ejemplos de realizacion, a cuya descripcion se remite en el presente documento. En un suministro de un elevador de granulado de asfalto reciclado 16 esta dispuesta la cinta de adicion 12. Una bascula de cinta 17 y un elemento de deslizamiento 18 unen el elevador de granulado de asfalto reciclado 16 con una mezcladora 19. La diferencia esencial con respecto a los primeros cuatro ejemplos de realizacion consiste en que el calentamiento del granulado de asfalto reciclado 2 se efectua de manera discontinua. Para ello se anade la carga 3 en una cantidad correspondiente con la formulacion de asfalto a traves del sinfin de tubo 5 al granulado de asfalto reciclado 2. El granulado de asfalto reciclado 2 al que se ha incorporado la carga 3 se transporta a traves de la cinta de adicion 12 y el elevador de granulado de asfalto reciclado 16 a la bascula de cinta 17, donde se pesa el granulado de asfalto reciclado 2 al que se ha incorporado la carga 3. A traves del elemento de deslizamiento 18 se transporta el granulado de asfalto reciclado 2 frio al interior de la mezcladora 19, en la que se encuentra material blanco 8 sobrecalentado.Next, a fifth example of embodiment of the invention is described with reference to Figure 5. Identical parts from the constructive point of view obtain the same references as in the first four examples of realization, the description of which is referred to herein. In a supply of a recycled asphalt granulate elevator 16, the addition belt 12 is arranged. A belt scale 17 and a sliding element 18 connect the recycled asphalt granule elevator 16 with a mixer 19. The essential difference with respect to to the first four examples of embodiment, the heating of the recycled asphalt granulate 2 is carried out discontinuously. For this purpose, load 3 is added in an amount corresponding to the asphalt formulation through the tube auger 5 to the recycled asphalt granulate 2. The recycled asphalt granulate 2 to which the load 3 has been incorporated is transported through the Addition belt 12 and the recycled asphalt granule elevator 16 to the belt scale 17, where the recycled asphalt granulate 2 to which the load 3 has been incorporated is weighed. The granulate is transported through the sliding element 18 2 cold recycled asphalt inside the mixer 19, in which white material 8 is superheated.
El granulado de asfalto reciclado 2 se obtiene mediante la eliminacion por fresado de revestimientos de calles reciclados. En funcion del procedimiento de eliminacion por fresado usado puede variar el tamano del diametro de particula, caracterizandose el granulado de asfalto reciclado 2 de grano fino por diametros de particula inferiores a 10 mm, en particular inferiores a 5 mm y en particular inferiores a 2 mm.The recycled asphalt granulate 2 is obtained by milling of recycled street coatings. Depending on the milling elimination procedure used, the size of the particle diameter may vary, characterized by the recycling of fine-grained asphalt granules 2 by particle diameters smaller than 10 mm, in particular less than 5 mm and in particular less than 2 mm .
La carga 3 producida en la eliminacion de polvo presenta particulas con diametros entre 0,9 mm y 2,0 mm, en particular de 1,5 mm a 2,0 mm y se denomina, por tanto, carga gruesa. La carga gruesa es especialmente ventajosa para incorporarla al granulado de asfalto reciclado 2, ya que la carga gruesa como producto de la eliminacion de polvo esta presente calentada y, con ello, se favorece la union de granulado de asfalto reciclado 2 con la carga gruesa. La incorporacion al granulado de asfalto reciclado 2 es posible tambien con la denominada carga fina, que se caracteriza por diametros de particula entre 0 mm y 0,9 mm, en particular de 0,1 mm a 0,9 mm, en particular de 0,5 mm a 0,9 mm. En funcion de la especificacion del pais, la separacion entre carga fina y carga gruesa puede situarse en lugar de en 0,9 mm tambien en 0,63 mm.The charge 3 produced in the removal of dust has particles with diameters between 0.9 mm and 2.0 mm, in particular from 1.5 mm to 2.0 mm and is therefore called a thick load. The thick load is especially advantageous for incorporating it into the recycled asphalt granulate 2, since the thick load as a product of the dust removal is present heated and, thereby, the union of recycled asphalt granulate 2 with the thick load is favored. The incorporation into the recycled asphalt granulate 2 is also possible with the so-called fine charge, which is characterized by particle diameters between 0 mm and 0.9 mm, in particular from 0.1 mm to 0.9 mm, in particular from 0 , 5 mm to 0.9 mm. Depending on the specification of the country, the separation between fine and coarse load can be placed instead of 0.9 mm also in 0.63 mm.
El procedimiento de acuerdo con la invencion para la preparacion de asfalto se basa en la adicion de granulado de asfalto reciclado 2 a material blanco 8, puede usarse para muchos procedimientos conocidos de calentamiento de granulado de asfalto reciclado 2 y esta disenado de tal modo que pueden hacerse funcionar procedimientos e instalaciones ya existentes para la preparacion de asfalto, que no tienen en cuenta la adicion de granulado de asfalto reciclado 2, completando componentes correspondientes de acuerdo con el nuevo procedimiento.The process according to the invention for the preparation of asphalt is based on the addition of recycled asphalt granules 2 to white material 8, can be used for many known methods of heating recycled asphalt granules 2 and is designed in such a way that they can operating existing procedures and facilities for the preparation of asphalt, which do not take into account the addition of recycled asphalt granules 2, completing corresponding components in accordance with the new procedure.
