Definitions

  • the invention relates to a method for producing joint-shaped Seams on partial surfaces of asphalt surface courses.
  • seams is used in the following as a generic term used for both seams and connections. Stitching in the true sense arise from the combination of side-by-side installation tracks made of mixed material with comparable Characteristics. Connections are the connections of installation tracks made of mixed material with different properties. These include rolled asphalt (asphalt concrete, stone mastic asphalt) on mastic asphalt and vice versa. The connection from mastic asphalt to mastic asphalt is also a connection to manufacture. A special need for so-called Connections arise when building "new” against “old”, because here the difference in the properties of the to be introduced Covering layer materials alone just by the length of time is given regardless of the type of mix the areas to be connected.
  • connections are therefore very high. They should be waterproof, i. H. not yourself open under the influence of traffic and climate. It applies therefore, more bitumen than before on the connecting flank bring to. This is particularly important for connections.
  • the goal must be, at this point a soft one Install the joint, i.e. a maximum amount of bitumen to the Placing poems, moving and sticking.
  • the invention has for its object a method to create, by the disadvantages described above be avoided.
  • the object is achieved according to the invention by a method for producing joint-shaped seams on partial surfaces of Asphalt surface courses by applying a band-shaped Bitumen material along the seam flank of a partial surface in such a way that the bitumen material at least through mechanical action plasticized and through a molding nozzle pressed out in the form of a strand and pressed against the seam flank becomes.
  • This thermal Action can be in the area of mechanical Take effect on the bitumen material or else in the area of the molding nozzle to determine the flow behavior and the Plasticity in this area, especially at low ones Temperatures to influence favorably.
  • the method according to the invention can be carried out according to the invention with a device for producing joint-shaped seams on partial surfaces in asphalt cover layers by applying a band-shaped bitumen material along the seam flank of a partial surface a wheeled chassis on which a continuous promoting, drivable kneading device arranged is that with a feeder for the to be processed Bitumen material and with a shaping nozzle for the plasticized Bitumen material is provided.
  • the kneading device can be in the manner of an extruder be built up in a housing a kneading and conveyor screw has, with the help of the feeder imported bitumen material kneaded, here is plasticized and pressed out through the molding nozzle. If the undercarriage is now moved, this can be done from the molding nozzle emerging plasticized band-shaped bitumen material on the seam flank to be machined of the existing one Partial area filed and by hand, for example pressed with the help of a spatula-shaped tool will. Because of the plasticization high plasticity of the bitumen tape produced in situ sufficient manual strength is sufficient to hold the bitumen tape for example, seam flanks provided with breakouts to express that there is a good connection.
  • At least the kneading device with one is expedient Heating device provided for reliable plasticization to ensure.
  • the heating device by a Heat transfer surface is formed by the exhaust gases of an internal combustion engine driving the kneading device is applied.
  • the available through the exhaust heat standing heat is sufficient to control the temperature of the kneading device off, so that carrying an additional energy supply, for example in the form of a propane gas burner, can be omitted.
  • At least one wheel of the chassis with the drive motor the kneading device, preferably depending on the spreading speed of the kneading device controllable communicates.
  • This is a tension-free uniform laying of the plasticized to be applied Bitumen tape guaranteed. It is useful here when the molding nozzle with its ejection direction against Direction of travel of the landing gear is aligned, it is also advantageous if the molding nozzle under a small angle of attack directed against the seam flank is.
  • a pressure element for that from the molding nozzle emerging band-shaped bitumen material is provided.
  • the pressure element can, for example be designed in runners or also in roll form, whereby at least the surface of the pressure element from one Material must exist on which the plasticized bitumen material not attached. It is also expedient here if the pressure element, based on the direction of travel, is arranged close behind the molding nozzle.
  • the pressure element relative to the chassis adjustable in height is connected to this.
  • the pressure element against the Bottom surface next to the seam flank designed to be pressed on is, so that it is ensured that the applied plasticized bitumen tape also over the full height of the Seam flank is pressed.
  • the undercarriage with attachable to the seam flank preferably transverse adjustable relative to the chassis Guide elements is provided. This is a basic positioning of the undercarriage with respect to the seam flank ensured so that the compensation of unevenness can be done via the pressure element. Conveniently becomes at least one guide element in the area of the pressure element arranged.
  • the feeder with a depending on the discharge speed of the kneading device Feed device for the bitumen material is provided.
  • the term pinch roller assembly affects both oppositely driven Pinch rollers as well as at least two parallel to each other arranged conveyor belt-like clamping devices, so that the expediently preformed bituminous bituminous Feed material that is deformable to a certain extent is reliably drawn in.
  • the device shown in Fig. 1 in a side view consists essentially of a wheeled 2 Chassis 1, which has a guide drawbar 3, on the the necessary controls are arranged.
  • a kneading device 4 is arranged on the carriage 1, which consists essentially of a housing 5 in which a kneading screw 6 is rotatably supported by a Drive motor 7, for example a small gasoline engine is driven.
  • the housing 5 has on one End of a receiving funnel 8 with a feed device 9 is provided, which consists essentially of two parallel pinch rollers or clamping band arrangements, such as shown exists.
  • the feeder is over Transmission means not shown here with the Drive motor 7 connected, so that in the form of a rod 10th supplied bitumen material to be processed with a corresponding force is pressed into the receiving funnel 8 and is detected by the kneading screw 6.
  • a molding nozzle 11 is provided on the other end the kneading device 4.
  • the bitumen material fed in via the feed device 9 is caused by the mechanical action of the kneading screw 6 plasticized and through the molding nozzle 11 as plastic Band pressed out.
  • the molding nozzle 11 expediently has a rectangular cross-section which, in its greatest extent, d. H. its height, slightly larger than that Thickness of the existing cover layer 12 and that in its Width is tailored to the specific application. Depending on the application, widths are between 8 and 20 mm possible.
  • a pressure element on the chassis 1 16 for example arranged in the form of a roll.
  • the pressure element 16 can, for example, under the action of a spring element 17 through which the pressure element 16 with a predetermined, preferably adjustable contact force against that from the molding nozzle 11 emerging plasticized bitumen tape 15 is pressed, so that this against the seam flank 13 with a predetermined Force is pressed and pressed into all bumps.
  • the pressure element 16 is expediently on a holding device 18 attached, which in turn over a Roller 19 on the surface 14 or the top layer 12 trailing supports, so that for the pressure element 16th a precisely defined altitude is always maintained.
  • the holding device 18 can be articulated to the undercarriage be and under your own weight or if necessary by an additional weight is pressed against the surface 14, to prevent the pressure element from migrating upwards.
  • the wheels 2 on the chassis 1 can, as in the supervision acc. Fig. 2 shown obliquely at a small angle be set so that when feeding the device in Direction of arrow 21 the chassis 1 against the seam flank 13 is pressed, the wheels then with the corresponding Roll slip over surface 14.
  • guide elements 22, for example guide rollers on the chassis 1, is one perfect system and thus perfect positioning the chassis to the seam flank 13 guaranteed.
  • the drive motor 7 with at least one of the wheels 2 on the chassis 1 via a gear arrangement 23, for example a belt or chain drive, is connected, so that the drive motor for the kneading screw 6 at the same time also causes the feed of the device as a whole.
