Definitions

  • This recycling process involves the reprocessing made of the milled material on the spot, so that the transport of the milled material to a Processing plant and return transport to the construction site not applicable.
  • EP-A-0 158 560 describes a method for the restoration of damaged ones Roads where the road surface is not milled, but in blocks broken out and then crushed.
  • the shredded material becomes a Correction granules added, the amount from an analysis of the crushed Material is determined. It also becomes a solid binder Mixing ratio added.
  • EP-A-0 237 424 proposes binding agent (cement) to the milled material. and add water, the amount of cement and water depending is calculated from the feed rate of the road rehabilitation machine.
  • EP-A-0 316 752 discloses a device for the rehabilitation of Road construction layers with a storage silo for the old material.
  • the Waste material gets into a crusher, the additional material components can be fed to different containers.
  • a device for the renovation of damaged roads is also out of the FR-A-2 586 435 known.
  • An analysis of the road surface to be refurbished is not made in the known device.
  • the amount of to be added The material is only determined depending on the feed of the machine.
  • EP-A-0 274 920 describes a cold recycling process in which only Binder is added to the material to be processed in order to achieve an optimal To achieve compaction. Mineral aggregates are not the material admitted.
  • the invention has for its object to provide a method with which the on-site shredded ceiling material in an optimal Composition can be reprocessed.
  • the solution to this task takes place according to the invention with the features of claim 1.
  • the invention has for its object a device for To carry out the procedure. This task is accomplished with the Features of claim 7 solved.
  • the composition of the road structure to be renovated was determined and the like Data obtained are entered into a computer which, depending on the materials to be added to the entered target values required quantity and grain size determined and immediately the addition of mineral Ingredients as well as the binder defined and to the corresponding Control-regulating actuators exist that control and regulate accordingly.
  • a reconditioned product is thus used Receive material that has an optimal composition and thus in installed condition in all requirements of modern road traffic to the full extent.
  • the mineral constituents are advantageously added via Conveyor belts or screw conveyors depending on the Feed rate of the recycling machine can be controlled.
  • Liquid Binding agents are advantageously supplied via appropriate metering pumps added and cement, which is powdery per se and so far by means of a Gritter was spread on the road surface to be renovated expediently added as a cement slurry (suspension).
  • the dosing devices for those provided on the recycling machine Components are taking into account those determined by analysis
  • the composition of the old road superstructure can be controlled and / or regulated. On this way changes in the composition of this old Road construction immediately by changing the additions on the Recycling machine to be balanced.
  • composition and the Grain size composition of the resulting from the milling of the old layers Material to adapt to the necessary compositions much more precisely, around an optimal composition range and thus all requirements appropriate material for modern reinstallation receive.
  • any mixer such as a compulsory mixer, can be used as the mixing device Find application. It has proven particularly advantageous, however, that Milling drum itself as a mixing device and / or in connection with a mixer for the components to be mixed.
  • the mineral components and on the other hand the binder component (s) in the expediently by a front cover plate and a rear Scraper plate locked space of the milling drum entered and with the milled material intimately mixed. Via an outlet in the rear Scraper blade leaves the material in the milling drum room and becomes, if necessary additionally passed into a mixer.
  • the finished mixed material is then picked up by the auger and in line with the profile by the installation unit installed and compacted.
  • the cement component can be used for the recycling material required amount of water according to the amount of cement added be premixed into a suspension.
  • the component Bitumen emulsion can be used in the same way as water added by computer controlled and / or regulated feed pumps become. Here the bitumen emulsion with the cement suspension mixed and across the width of the Milling drum in the milling drum room and / or in the mixer sprayed. This makes the addition components more intimate mixed with the milled material.
  • the mineral components and the additional mix are preferably computer-controlled and / or regulated conveyor belts or screw conveyor provided the material from the storage container provided on the machine transport the milling drum space, where the same with the milled material is mixed.
  • Milling the old road superstructure to the required Depth of up to 40 cm across the entire width of a lane requires an extraordinary massive education the machine and relatively large power reserves of the drive motor. Due to the high performance of the recycling machine the consumption of additives is very high.
  • the transport vehicles with the addition components arranged on them expediently drive in front and / or behind of the recycling machine and deliver the addition components in the desired amount directly to the dosing devices.
  • the necessary funding facilities are once for the Liquid components, preferably hoses with quick-release fasteners and conveyor belts for the mineral components or screw conveyors where the drive and thus the output is also controlled or regulated.
  • the inventive Method and the intended invention Device a substantial improvement of the so-called Cold recycling process is achieved in that that differences in the recycled material the old road surface on the recycling machine can be, so that with 100% reinstallation of the milled material optimal compositions of cold-recycled Locations can be reached so that all layers of the road were renovated using the cold recycling process Meet the requirements of modern road traffic.
  • bituminous are at the required depth of up to 40 cm Layers 2 and / or the gravel layer 1 underneath milled and crushed according to the inventive method, with mineral components in the required Grain size and quantity and with binder (s) made of cement, water and / or bitumen emulsion mixed and to the cold-recycled layers 3 as below the designation "after" are shown.
  • binder s
  • Figure 2 shows a schematic side view of a device to carry out the method according to the invention with a self-propelled undercarriage on tracks 1,2 and below arranged motor-driven milling drum 3 and one Installation unit 4, for the storage container with dosing device for mineral component (s) 5 and for the Binder components 6.7 are provided.
  • a mixer 12 arranged behind the milling drums is used in connection with the milling drum to mix the milled Materials.
  • the mineral components 5 are in the longitudinal direction divided containers into several different ones Compositions are present and are delivered via the transport facility 8 fed to the milling drum room. In this milling drum room and / or the nozzles also open into the mixer 9 and 10, with which the cement suspension and / or the bitumen emulsion is sprayed.
  • FIG. 3 shows another in a schematic side view Device for carrying out the method according to the invention, also with a self-propelled chassis Caterpillars 1,2 and motor-driven arranged below Milling drums 3, which are variable in their working width and so can be adapted to the respective road width.
  • the installation unit, storage container, dosing devices for mineral components 5 and for the binder components 6,7 correspond to the device according to FIG. 2.
  • Storage containers 5 to 7 can, according to another embodiment of the present invention at this point too only the connecting piece together with the dosing and control unit be provided to the one hand the liquid binder and on the other hand also the mineral component 5 of to take over a preceding vehicle. It can of course also use smaller storage containers be retained as a buffer container to the recycling company also when changing the transport vehicle maintain.
  • the mineral components are conveniently transported via a conveyor belt or a screw conveyor, the possibly running in a conveyor pipe.
