Definitions

  • the present invention relates to a device for producing, in particular renovating, road surface layers, preferably using the old materials removed from the road.
  • the focus is on so-called cold recycling, in which an attempt is made to reuse the bituminous covering material that has been removed from the road surface by breaking or milling.
  • the old material is first fed to a crusher for breaking and homogenization, in order to then prepare the old material ready for installation with the addition of bitumen emulsion in a mixing plant, after which the material is applied to the road to be renovated.
  • the object of the present invention is therefore to create a device of the aforementioned type which allows a cold recycling rehabilitation process of roads which is relatively independent of the material properties to be carried out rationally and in an environmentally friendly manner on site.
  • a receiving silo for the old material supported on a chassis supported by motor-driven undercarriages, which can be fed to a subsequent crusher, preferably in a metered manner, the crusher being connected via metering conveying means to a mixing mechanism also supported on the chassis, the addition -Material components can be fed from at least one additional container supported on the chassis and from which the ready-to-install material can be fed via augers to a screed drawn from the chassis.
  • Such a facility can not only do that from the street Continuously pick up worn material, homogenize, process and reinstall, but also allows cold recycling of milled or. broken old asphalt, the creation of cold mix foundation layers with bitumen emulsions and, among other things, the hydraulic stabilization of various mineral base materials and their direct installation to base and foundation layers.
  • this device not only to renew bituminous coverings, but also to no longer renovate sufficiently load-bearing roads by first storing the milled old asphalt and storing the existing case, for example non-frost-resistant gravel sand, in a predetermined layer thickness, e.g. 15 cm, is dredged.
  • This material then first reaches the receiving silo of the device according to the invention, in order to then process it with bitumen emulsion and / or cement, lime, fly ash, etc. to be reinstalled directly as a cold mix foundation layer.
  • the temporarily stored old asphalt is fed to the device according to the invention, processed by it and then directly installed as a base course or final covering.
  • the wear layer is prepared with cold micro-topping and can be reinstalled directly.
  • a street renovated in this way surpasses the qualities of streets rehabilitated according to previous cold recycling processes and extends its field of application very decisively, the renovation using the device according to the invention also being more cost-effective and much more environmentally friendly.
  • the metering conveying means comprise a scraper belt between the crusher and the mixer
  • the chassis is also box-shaped and divided into additional containers for fuel, additives and hydraulic oil
  • the chassis furthermore has a preferably exchangeable additional container for granular resp. comprises dust-like components, the screw-controlled outlet of which opens out above the conveying means either in front of the crusher or in front of the mixer.
  • chassis carries an additional container which serves to hold bitumen emulsion or water or the like and which at least partially surrounds the main motor unit to absorb radiant heat.
  • the main engine unit comprises a diesel engine, the cooling water circuit and / or the exhaust gas flow of which is led to heat exchange through the mixing unit, or. its cooling water circuit serves to preheat the additional components.
  • the frames are preferably box-shaped and thus give the opportunity to form chambers for receiving fuel, hydraulic oil and liquid additives (not shown in more detail).
  • the trolleys 1, 1 ', 2 and 2' can be commercially available, hydraulically driven caterpillar single trolleys that allow the relatively long and heavy facility to move. Vehicles of this type are known per se, so that a detailed description of the structure, drive and control is unnecessary here.
  • a receiving silo 4 for the preferably old material is arranged on the front of the chassis 3, from where the old material can be fed to a subsequent crusher 5 in which the old material is broken and homogenized.
  • the arrangement is such that the material in the silo 4 via an inclined surface to the crusher 5, respectively. slips to a so-called scraper belt 6, a simple metering rake being sufficient to effect a suitable oversize separation (not shown).
  • vibrating surfaces are also u. Like. conceivable.
  • the crusher includes a crusher and a calibration device that is suitable for all larger chunks of material to be taken up by the lower scraper belt 6 and lead into the area of the crusher (not shown).
  • a mixer 7 is arranged downstream of the crusher 5 and supported on the chassis 3, the crusher 5 being connected to the mixer 7 via metering conveying means.
  • the funding can be the aforementioned scraper belt 6, the transport speed and the size of the expedient slide-controlled outlet opening on the crusher 5 allowing volumetric metering (not shown).
  • the mixer 7 is advantageously a two-shaft mixer 18 (FIG. 5) for the greatest possible mixing effect, in particular also for the preparation of stabilizing material.
  • the mixer 7 then pushes its mix in front of a so-called screed 14 arranged at the end of the chassis 3, where the ready-to-install material is picked up by screw conveyors 13 and distributed uniformly over the width of the screed 14.
  • the installation of the prepared mix using screed is known and need not be explained here.
  • the invention provides for the mixer 7 to be supplied with additional material components from at least one additional auxiliary container supported on the chassis 3 .
  • a first additional material component in the form of, in particular, bitumen emulsion or water is removed from an additional container 9 which is fixedly mounted on the chassis 3 and which at least partially surrounds the main motor unit 15 of the device in order to heat the radiant heat of the motor unit to heat up the contents of the additional container 9 benefit.
  • bitumen emulsion or the water can then be passed into the mixer 7 via suitable dosing means (not shown).
  • cooling water of the engine 15 can be passed through the mixing unit 7 via a suitable heat exchanger system 16, or can be used for preheating the additional components.
  • a preferably replaceable additional container 8 arranged on the chassis 3, the screw-controlled outlet 12 and. 12 'either in front of the crusher 5 or at the upper end of the scraper belt 6 before the mixer 7 opens.
  • This arrangement permits precise volumetric metering of the granular additional components removed from this container.
  • Hydraulic and electrical drive functions are advantageously derived from the main motor unit 15.
  • the trolleys, the crusher, the mixer, the screed, the steering, etc. can be driven hydraulically, whereas all metering drives, the valves, the control flaps and the control electronics are operated electrically.
  • the device according to the invention for the rehabilitation of road surface layers now allows the inclusion of any minerals in the form of milled old asphalt, gravel of various qualities, rubbish slag, etc., which materials are then preferably broken and homogenized in a continuous process and in volumetric, possibly weighed, dosage get to the mixer with the possible addition of one or more metered liquid components at the same time.
  • a dusty component such as cement and / or lime, etc. be added.
  • this facility basically allows the preparation and installation of new materials.
