Definitions

  • the invention relates to a method for producing compact asphalt pavements with at least two-layer installed asphalt asphalts, which are installed with several asphalt pavers.
  • Asphaltbinder- or Asphalttragtik creates a stable substrate for the asphalt surface course.
  • the former hot on hot process is divided into two sub-processes.
  • the upper layer is installed without passing through the lower layer with a special finisher, a so-called compact module finisher.
  • a so-called compact module finisher a so-called compact module finisher.
  • Kompaktmodulfertiger are expensive and can usually only partially be utilized. Thus arise high costs in the Production of such asphalt pavements using compact modular pavers.
  • two conventional pavers travel in succession.
  • the second paver who installs the upper layer, has to drive the lower layer.
  • the first paver used to install the lower layer already causes pre-compaction of the lower layer.
  • such pavers are designed so that there is no significant deformation of the lower layer when driving the lower layer with the second paver. Nevertheless, asphalt layers that are not yet fully compacted should only be used as little as possible.
  • the second asphalt paver for installing the upper layer - as well as the first paver - has to be repeatedly supplied with asphalt. This is problematic because the first paver has to drive a short distance in front of the second paver.
  • the asphalt of the lower layer should namely cool as little as possible before the upper layer is applied. Furthermore, the lower layer should not be traveled unnecessarily with feed vehicles.
  • the feeder would have to transport the asphalt to be delivered over the first paver to the second paver.
  • Appropriate transport routes are high and long. They are therefore complicated and expensive. Furthermore, they entail a considerable risk of accidents since the conveying path passes over the driver's cab of the first paver. On the driver could therefore fall down hot asphalt.
  • a lateral loading of the second, the upper layer producing asphalt paver is also often problematic, as provided for such a feeder in many cases no lane next to the asphalt pavement to be created.
  • the invention is therefore an object of the invention to improve the loading of asphalt pavers for the upper layer using conventional pavers.
  • the invention solves this problem with a method according to claim 1, namely with a method for producing compact asphalt pavements with at least two layers built Walzasphalten, which are installed with several asphalt pavers, each at least one - viewed in the direction of the asphalt paver - laterally arranged next to the respective asphalt paver have lateral screed for installing asphalt, with at least a first asphalt paver, a lower layer and at least one second asphalt paver an upper layer of the asphalt pavement is installed, the first asphalt paver or the second asphalt pavers ahead with a longitudinal offset in the direction of travel or advance, wherein the first or the first asphalt pavers furthermore travel with a transverse offset transversely to the direction of travel to the second asphalt paver (s), the transverse offset being dimensioned such that at least one feeder, if necessary with an offset in the direction of travel, can drive laterally next to or one of the first asphalt pavers and in the direction of travel before or one of the second asphalt paver to asphalt from this feeder on the - as seen in the direction of travel - in front
  • the invention is based on the finding that asphalt pavers can be installed with high quality even with asymmetrical attachment of screeds, that is to say with an attachment only on one of both sides of the paver. It is therefore possible to operate two asphalt pavers to be operated in succession for different layers laterally offset from one another, ie to move forward in the direction of travel or road, in order to install asphalt. Due to the lateral offset of a first asphalt paver for installing a lower layer to a second asphalt paver for installation an upper layer is located in front of the second asphalt paver only the lateral screed of the preceding first asphalt paver, but not the entire first asphalt paver with chassis, superstructures and reservoir. Possibly. At least partially in front of the second, that is to say rear asphalt paver, there are two overlapping lateral screeds of two essentially adjacent preceding asphalt pavers for installation of the lower layer.
  • these screeds are low compared to an asphalt paver. It is therefore possible with such an arrangement of the asphalt paver for installation of the lower and the upper layer to bring a feeder for feeding the asphalt paver for the upper layer close to its reservoir, without having to ride on one of the already created asphalt layers and without doing a additionally lane next to the roadway to be created would have to be kept ready. Rather, the feeder can essentially - viewed in the direction of travel - directly in front, i. essentially on the longitudinal axis of the topping asphalt paver to be fed in order to convey material into the asphalt hopper of this asphalt paver.
  • the invention achieves this by the asymmetric cultivation of screeds to create in this way a lateral offset between a preceding and a trailing paver and thus space for a feeder before the trailing asphalt paver.
  • two first asphalt pavers build the bottom layer over the full pave width of the asphalt pavement, with only one sideways screed attached to each of these asphalt pavers.
  • Each of these lateral screeds extends in each case substantially in the direction of the other of the two asphalt pavers for the installation of the lower layer. They thus extend in opposite directions.
  • the upper layer is installed over the full pave width of the asphalt pavement by means of exactly one second asphalt paver, wherein a lateral screed is attached to this asphalt paver on each side.
  • the lower layer is installed in two parallel, adjacent installation strips.
  • the upper layer on the other hand, is built up in one go, that is, without any seam on the lower layer. This results in particularly uniform road characteristics, since the road surface layer is formed homogeneously.
  • Figures 1 and 2 show several asphalt pavers in the manufacture of a multi-layered asphalt road.
  • Two first asphalt pavers 10, 12 incorporate a lower layer, namely an asphalt binder or asphalt base course.
  • Another asphalt paver referred to in the context of the present invention as the second asphalt paver 14, travels behind the first asphalt pavers 10, 12 and builds an upper layer, namely an asphalt surface course, onto the lower layer.
  • Each of the asphalt pavers 10, 12, 14 has a base pile 18, 20 and 22, respectively, which extends over the basic width A or B of the respective asphalt paver 10, 12, 14.
  • the pavers for installing a layer preferably have the same dimensions, that is, a same basic width A.
  • each a screed 24, 26 grown. These screeds are each aligned with the center of the roadway 28 to be created. Since the first two asphalt pavers with a - viewed in the direction of travel 16 - short distance C to each other, for example. 50cm to 100cm drive, the screed 24 of the left first asphalt paver 10 extends to the right, that is substantially in the direction of the right first asphalt paver 12. In a similar manner, the screed extends 26 of the right Asphalt Paver 12 to the left, that is substantially in the direction of the left Asphalt Paver 10th
  • All planks are designed as Glaverdichtungsbohlen. That means they provide a very high compression of the material to be incorporated. This means that in particular the lower layer is barely deformable.
  • Each of the first asphalt pavers 10, 12 builds a layer over a pave width D.
  • the resulting installation panels overlap by a distance E in the range of 1 cm to 25 cm, for example. 10cm.
  • the screeds 24, 26 typically have a low height of no more than 80cm, while the asphalt pavers 10, 12 can reach heights of 2 to 3 meters or more.
  • the asphalt pavers 10, 12 each have a reservoir 30, 32 for storing the material to be incorporated.
  • These storage containers 30, 32 can easily be filled via commercial vehicles, such as dump trucks or special feeders, since these vehicles can unload their material into these storage containers 30, 32 before the first asphalt pavers 10, 12. You do not have to drive on the layers installed by the asphalt pavers 10, 12, 14.
  • the subsequent second asphalt paver 14 builds the upper layer over the full carriageway width F.
  • screeds 34, 36 are mounted on the second asphalt paver 14 on both sides, so that the second asphalt paver 14 using the Base board 22 and the two screeds 34, 36, the entire roadway width F can coat.
  • the second asphalt paver 14 has a material bucket serving as a reservoir 38.
  • this reservoir 38 is required for the installation of the upper layer material. During the preparation of a road surface, however, this reservoir 38 must be replenished again and again. Due to the preceding first asphalt pavers 10, 12, however, this storage container 38 can not be filled in such a simple manner as the storage containers 30, 32. Instead, a special feeder is required for this purpose.
  • FIG. 3 shows in a simplified representation the arrangement of the asphalt pavers 10, 12, 14 shown in FIG. 2 and a feeder 40 in dashed lines.
  • This feeder 40 likewise has a storage container and a conveyor leading away from the storage container, for example a conveyor belt 42 on.
  • This conveyor belt 42 is arranged on a boom which extends from the feeder 40 in the direction of the storage container 38 of the second asphalt paver 14.
  • the conveyor belt 42 transports asphalt into the storage container 38.
  • the feeder 40 can approach very close to the second asphalt paver 14. Because of their small height and depth, these screeds 24, 26 do not constitute an obstacle to the feeder 40 or the conveyor belt 42 arranged thereon.
  • the feeder 40 may instead of a conveyor belt also have a screw conveyor or any other conveying mechanism.
  • the invention is not limited to the use of a conveyor belt.
  • a particular aspect of the present invention is the arrangement of the first paver 10, 12 to the second paver (s) 14.
  • the first Paver 10, 14 drive the second paver 14 not only by a longitudinal offset 44 and 46, that is, an offset in the direction of travel 16 ahead.
  • the first asphalt pavers 10, 14 furthermore travel with a transverse offset 48 or 50, that is to say an offset transversely to the direction of travel 16, with respect to the second asphalt paver 14.
  • This transverse offset 48 and 50 is dimensioned such that the feeder 40 can drive laterally next to the first asphalt pavers 10 and 12 and in the direction of travel 16 in front of the two asphalt paver 14. In this way, asphalt can be conveyed from the feeder 40 via the lateral screeds 24, 26 of the first asphalt pavers 10, 12 into the storage container 38 of the second asphalt paver 14.
  • This concept of a transverse offset of first and second asphalt pavers to one another in order to make room for a preceding feeder can also be implemented in further paver arrangements.
  • FIG. 4 shows a further exemplary embodiment for the arrangement of a first asphalt paver 52 and a second asphalt paver 54.
  • This embodiment differs from the exemplary embodiment shown in FIGS. 1 to 3 by a smaller roadway width. Due to a smaller roadway width not only the first asphalt paver 52 with only one screed 56 - in addition to a base bar 58 - but it is also the second asphalt paver only with a screed 60 - next to a base pile 62 - operated.
  • the second asphalt paver 54 travels with a transverse offset 64 behind the first asphalt paver 52.
  • a load of the container of the second asphalt paver 62 can be supplied via the feeder and a conveyor 42 with asphalt, the conveyor 42 passes over the screed 56 of the first paver.
  • Fig. 5 shows a further embodiment in a further development of the embodiment shown in FIGS. 1 to 3 for lanes with a larger Roadway width.
  • three first asphalt pavers 66, 68, 70 travel in front of two second asphalt pavers 72, 74.
  • first asphalt pavers 66, 68, 70 only one lateral screed 76, 78 is attached to the outer asphalt pavers 66, 70, while the middle paver 68 or possibly several such average asphalt paver with screeds 80 are provided on both sides.
  • the asphalt pavers 72, 74 of the group of second asphalt pavers are each equipped with screeds 82, 84 on both sides of the corresponding paver 72, 74.
  • the first asphalt pavers 66, 68, 70 travel at a transverse offset transversely to the direction of travel 16 to the second asphalt pavers 72, 74. Again, this respective transverse offset creates space next to the first pavers 66, 68 and 70, respectively, with one Feeder 40 and a conveyor 42 asphalt material to the second pavers 72, 74 on the screeds 76, 78, 80 of the first asphalt paver away to promote.
  • FIG. 6 shows a further embodiment, which largely corresponds to that shown in FIG.
  • first asphalt paver has two screeds 92, each mounted on either side of the first paver 86.

At least two asphalt pavers with only one side-mounted screed travels along the edges of the asphalt course to be installed, i. the roadway to be installed the roadway width F, so that in each case the lateral screed has from the respective lateral edge of the asphalt layer to be installed in the direction of the respective other lateral edge of the asphalt layer to be installed.
  • An asphalt paver travels along the left side of the asphalt layer to be installed in the direction of travel and has exactly one lateral screed pointing in the direction of the asphalt layer to be installed in the direction of travel.
  • Another asphalt paver travels along the right-hand side of the asphalt layer to be installed in the direction of travel and has exactly one lateral screed pointing in the direction of the asphalt layer to be installed on the left in the direction of travel.
  • these two asphalt pavers build asphalt with their respective basic screed up to an edge of the asphalt course to be installed in the area of the respective base screed.

  • Two second asphalt pavers are both fed via one lateral screed of the first asphalt paver. In each case, only a lateral screed is attached to these second asphalt pavers, which extends in each case substantially in the direction of the other of the two asphalt pavers.
  • an asphalt paver having just one side screed builds the lower layer ( Figure 4).
  • a second asphalt paver which has just one lateral screed pointing in the direction of the other lateral edge of the asphalt course to be installed, like the side screed of the first asphalt paver, constructs the upper layer.

  • each asphalt paver of the second row can be fed via lateral screeds of two preceding asphalt pavers away from a substantially preceding feeder. This is achieved by a transverse offset between asphalt pavers of the first and second series.

  • the space between two adjacent asphalt pavers is therefore almost as large as the total width of the paving widths of the side screeds of these adjacent asphalt pavers pointing in the direction of the other asphalt paver. It Therefore, there is sufficient space available to allow a feeder between two adjacent asphalt pavers with sufficient safety distance to drive this asphalt pavers and can feed the feeder itself, such as a truck easily.
  • more than one further asphalt paver is arranged between the two asphalt pavers moving in the first row on the roadway edges.
  • the number of second-row asphalt pavers is one less than the number of first-row asphalt pavers.

  • the lateral spacing of the asphalt pavers traveling side by side is measured.
  • This measurement can be done, for example, by means of ultrasound or by means of a laser.
  • the measured distance is fed to an automatic distance control, so that the distance adjacent distance pavers can be maintained constant.
  • the distance control intervenes in the control of the respective asphalt paver.
  • the invention enables the use of conventional asphalt pavers and eliminates the need for special compact modular pavers with which two layers can be installed without having to drive the lower layer. Thanks to the invention, therefore existing conventional asphalt pavers can be used much more economically. Furthermore, the required transport and set-up costs when using conventional pavers are significantly lower than when using special compact module tills.
