    Process for the production and installation of an asphalt building material suitable for cold incorporation and corresponding asphalt building material
    description
    The invention relates to a process for the preparation of a suitable for Kalteinbau 5 asphalt construction material for road construction, using a coarse-grained cavity cold asphalt mixture comprising a mineral stoffmömung and a Bitumenbindemittel for enveloping wetting of Mineralkömung in an aqueous emulsion, and a filler for the cavities containing a mortar binder and fine-grained washed sand 10 as solid base materials. The invention also relates to a suitably produced asphalt building material and to a method for the production, in particular for repairing a road surface using the proposed asphalt building material.
    Asphalt construction materials suitable for cold application and for cold incorporation are known in 15 different compositions and with different preparation processes from the prior art and are generally referred to by the person skilled in the art as cold asphalt. Asphalts are generally mixtures of bituminous binders and mineral aggregates, which are mainly used in road construction for roadway attachment, wherein the mixing ratio is roughly 95% mineral aggregate and 5% bitumen binder and the bitumen binder envelops the mineral aggregate. The mineral grain takes over the support function in the asphalt. Minerals used for the Mineralkömung according to the prior art natural minerals in the form of crushed rock such as gravel, grit, crushed sand or the like. For the support and / or cover layers for roadway production or -emeuerung usually hot asphalt is used, which is mixed at a temperature of about 200 ° and discharged at a temperature of at least 160 to 180 ° and compacted. * ·· *
    In contrast, cold asphalt is usually mixed cold and can be processed to freezing point. It is particularly suitable for smaller traffic areas and for repairing small-surface damage in asphalt pavements, such as frost damage or potholes. Cold asphalt differs from the hot asphalt substantially in the mixture in that the coarse cavity rich cold asphalt mixture comprises the bitumen binder for enveloping wetting of the mineral aggregate in an aqueous emulsion. Only when compacting and the subsequent desiccation of the cold asphalt mixture, the mineral grain and the bitumen binders enter into a surface-activated compound, the bitumen then being permanently bound to the mineral grain and holding the mineral grain together. It is important that the cold asphalt mixture hardens only in contact with the ambient air. Thus, the cold asphalt mixture packed in airtight containers can be stored in a workable state for a longer period of time, which makes the cold asphalt the ideal building material for smaller asphalt repairs.
    The strength of asphalt is basically determined by the temperature conditions. At low temperatures (winter), it behaves elastically, at high temperatures (summer) viscose elastic. In order to produce a completely homogeneous sealing lining, which is characterized by uniform elastic properties, a high load-bearing capacity and stability, it is necessary to completely fill the cavities in the coarse-grained cold asphalt mixture with a filler. For example, a mortar mixture which is mixed with the cold asphalt mixture and penetrates completely into its cavities is suitable as the filler.
    The published patent application DE 10 2006 060 985 A1 discloses a method for producing a semi-rigid covering for traffic areas using a mineral grain mixture coated with bituminous binders and a mortar mixture. In the known method, the cold asphalt mixture and a mortar mix adapted thereto are provided without water. Subsequently, a total mixture is prepared, consisting of the 3
    Cold asphalt mixture and the mortar mixture, which is mixed with water, whereupon the installation can be done on site.
    The addition of adding water results in a highly viscous flowable asphalt building material which is easy to process and which does not necessarily have to be compacted after installation. However, the addition of water has a detrimental effect on the time until the load capacity of the repaired road surface. In addition, the known building material can only be processed at temperatures above the freezing point of the addition water.
    Based on the described prior art, the present invention seeks to propose a way to reduce the time to the load capacity of the road surface and also to allow installation at low temperatures.
    This object is achieved by a method for producing a suitable for Kalteinbau Asphaltbaustoffes with the features of claim 1, a corresponding Asphaltbaustoff with the features of the independent claim 5 and a method for manufacturing, in particular for repairing a road surface with the features of claim 8. Further advantageous embodiments are shown in the respective dependent claims.
    The invention is based on the core idea of significantly reducing the water content of the asphalt building material to be cold compared to the prior art. The proposed method employs a conventional coarse cavity rich cold asphalt mixture comprising a mineral granule and a bitumen binder for encircling the mineral granules in an aqueous emulsion, and a filler for the cavities containing a mortar binder and fine-grained washed sand as solid precursors. According to the method of the invention, the solid base materials of the filler are mixed with the cold asphalt mixture without addition of adding water. During the mixing process, the aqueous emulsion of the cold asphalt mixture is deprived of the contained water by the mortar binder. f · «· · · · · ··· * * * * * * * * * * * * * * * * · ......... ST " ·
    The water taken up by the mortar binder causes a chemical reaction of the mortar binder, so that the mortar mixture can harden.
    In this case, preferably pure cement or a cement-lime mixture is used as a mortar binder. By the variable adjustment of the lime content and optionally by the addition of additives, the properties of the coating can be changed, in particular with regard to the strength, elasticity and abrasion. The cold asphalt mixture and the mortar mixture are expediently mixed exclusively in the cold mixing process, for example in a mixing drum of a forced mixer. The cavities in the cold asphalt mixture are filled with the mortar mixture, in particular with the sand of the filler, whereby the mortar binder largely adheres to the bituminous binder, which envelops the Mineralstoffkömung.
    Preferably, the cold asphalt mixture, the mortar binder and the sand are mixed together in a mixing ratio of about 10: (2-3) :( 1-2). The volume ratio when using pure cement as a mortar binder is typically 10: 2: 1, when using a cement-lime mixture as a mortar binder in about 10: 3: 2. A mixture of cement and lime of 2: 1 has proved to be especially favorable for a mortar binder composed of cement and lime.
    In a preferred embodiment of the method according to the invention, after the provision of the cold asphalt mixture and the precursors of the filler, the mortar binder is first added to the mixing drum of the forced mixer and distributed therein by rotating the mixing drum. Subsequently, the cold asphalt mixture and the sand is added in any order, wherein initially an intermediate mixture of the mortar binder and the cold asphalt mixture or the mortar binder and the sand can be prepared before the respective other substance is supplied. It is also possible to mix the cold asphalt mixture and the sand of the standing mixing drum with it
    distributed mortar binder sequentially or collect and mix in a single mixing with the mortar binder. By first placing the mortar binder in the mixing drum where it is evenly distributed and then adding the cold asphalt mixture, adherence of the cold asphalt mixture to the mixing drum can be reliably prevented. During the cold mixing process, the mineral aggregate covered with the bituminous binder is completely covered with the mortar binder so that a largely dry and therefore free-flowing asphalt building material is formed as a mixture.
    The asphalt building material according to the invention for cold pavement as a road surface has no addition water and thus a free-flowing consistency, after the coarse-grained hollow-rich cold asphalt mixture is mixed with the mortar binder and the washed sand of the filler. Advantageously, the Mineralstoffkömung, which is enveloped by the Bitumenbindemittel, encompassing covered with the mortar binder, wherein the fine-grained sand fills the cavities of the coarse-grained mineral grain. In this case, the proposed asphalt building material is preferably prepared according to the method described above.
    The method according to the invention for the production of a road surface using the above-described asphalt building material is intended in particular for the repair of road surfaces. The proposed method comprises producing the asphaltitious material preferably directly at the point of introduction, cold introduction of the asphaltitious material, and compacting the incorporated asphaltitious material to bond the mineral aggregate over the bituminous binder and completely filling the voids between the mineral aggregate covered with the bituminous binder through the filler. It goes without saying that the asphalt building material can also be produced away from the place of introduction and brought to the place of introduction, taking care that the asphalt building material is not over-compacted during transport and, in addition, that the setting time of the filler is not attained. This is usually only possible if the place of manufacture not far
    of the place of delivery. When compacting the cold-built asphalt material, nested support structures are formed by the cold asphalt mixture and the filler. The two support structures are in particular seamlessly interconnected, the filler additionally supporting the cold asphalt mixture 5.
