Description

Die Erfindung betrifft ein Fahrzeug zur Reparatur von Fahrbahndecken, insbesondere von Löchern und Spurrillen durch Ausfüllen mit einem Füllmaterial wie Asphalt und dergleichen, bestehend aus einer Erhitzungs- und Aufreißeinheit, einer Ausgabevorrichtung für das Füllmaterial und einem dahinter angeordneten Verdichtungswerkzeug.The invention relates to a vehicle for repairing road surfaces, in particular holes and ruts by filling with a filling material such as asphalt and the like, consisting of a heating and tearing unit, an output device for the filling material and a compression tool arranged behind it.

Derartige Fahrzeuge werden bis jetzt praktisch nur zur großflächigen Fahrbahn-Erneuerung eingesetzt, indem die alte Deckschicht abgetragen, aufbereitet und erneut aufgebracht wird, vgl. beispielsweise DE-OS 26 55 984. Soweit derartige Fahrzeuge zur lokalen Ausbesserung von Schlaglöchern oder dergleichen eingesetzt werden sollen, ergibt sich zum einen das Problem, das Füllmaterial in der richtigen Menge zu dosieren, weil der Bedarf je nach Größe und Verteilung der auszubessernden Stellen stark schwankt. Zum anderen ist es aus den gleichen Gründen schwierig, das aufgebrachte Material anschließend homogen zu verdichten.Such vehicles have so far been used practically only for large-area renewal of roads by removing, treating and reapplying the old surface layer, cf. for example DE-OS 26 55 984. Insofar as such vehicles are to be used for the local repair of potholes or the like, the problem arises on the one hand of metering the filler material in the correct amount, because the demand is strong depending on the size and distribution of the areas to be repaired fluctuates. On the other hand, it is difficult for the same reasons to subsequently compact the applied material homogeneously.

In der Praxis wird deshalb häufig eine Bedienungsperson außerhalb des Fahrzeuges eingesetzt, die manuell für die richtige Verteilung und Dosierung des Füllmaterials sorgt. Dieses Vorgehen ist jedoch aufwendig. Auch ist die Reparaturqualität von den Fähigkeiten der jeweiligen Bedienungsperson abhängig, unterliegt also Schwankungen und Zufälligkeiten.In practice, therefore, an operator is often deployed outside the vehicle, who manually ensures the correct distribution and metering of the filling material. However, this procedure is complex. That too is Repair quality depends on the skills of the respective operator, and is therefore subject to fluctuations and randomness.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Fahrzeug der eingangs beschriebenen Gattung dahingehend zu verbessern, daß damit nicht nur die Neubeschichtung ganzer Straßendecken, sondern vor allem das lokale Ausbessern von Fahrbahnschäden ermöglicht wird, wobei eine ausreichende, homogene Verdichtung unabhängig von der Größe und Verteilung der auszubessernden Stellen und ein bündiger Anschluß an den unbeschädigten Nachbarbereich der Fahrbahndecke gewährleistet sein soll.The present invention has for its object to improve a vehicle of the type described in such a way that not only the re-coating of entire road surfaces, but above all the local repair of road surface damage is made possible, a sufficient, homogeneous compression regardless of the size and distribution the areas to be repaired and a flush connection to the undamaged neighboring area of the pavement should be guaranteed.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Verdichtungswerkzeug die Verdichtung des aufgerissenen Materials und des zugegebenen Füllmaterials auf ein Niveau bewirkt, das höher liegt als die umgebende, unbeschädigte Fahrbahndecke und daß hinter diesem Verdichtungswerkzeug ein horizontal schwingendes Abziehwerkzeug zum Abtragen des Materialüberstandes angeordnet ist. Man gibt also mehr Material zu als zum Ausbessern der Schadstelle notwendig und führt dann eine Vorverdichtung auf ein künstlich erhöhtes Sollniveau durch, das etwa ein bis drei Zentimeter über dem unbeschädigten Niveau der Fahrbahndecke liegt. Danach wird in einem zweiten Schritt der Material überstand entfernt bei gleichzeitiger Verdichtung und Glättung der Fahrbahnoberfläche. Dieser zweite Verdichtungsvorgang schließt sich unmittelbar an den ersten an, so daß das Füllmaterial mindestens noch eine Temperatur von etwa 150 °C hat und gut verarbeitbar ist.This object is achieved in that the compaction tool causes the compaction of the torn material and the added filler material to a level that is higher than the surrounding, undamaged road surface and that behind this compaction tool a horizontally vibrating pulling tool is arranged to remove the excess material. So you add more material than necessary to repair the damaged area and then carry out a pre-compaction to an artificially increased target level, which is about one to three centimeters above the undamaged level of the road surface. Then, in a second step, the excess material is removed while the road surface is compacted and smoothed. This second compression process immediately follows the first, so that the filler material has at least a temperature of around 150 ° C. and is easy to process.

Es hat sich herausgestellt, daß mit diesen Maßnahmen eine ausgezeichnete Reparaturqualität schadhafter Fahrbahnen auf rein maschineller Basis ohne manuelle Einwirkung von Bedienungspersonen möglich ist, und zwar gleichgültig, ob es sich um Schlaglöcher, Frostaufbrüche, Spurrillen oder andere Schadstellen unterschiedlicher Größe, Tiefe und Verteilung handelt.It has been found that with these measures an excellent repair quality of damaged lanes on a purely machine basis is possible without manual intervention by operators, regardless of whether it is potholes, frost breaks, ruts or other damaged areas of different sizes, depths and distribution.

Zweckmäßig erfolgen die Horizontalschwingungen des Abziehwerkzeuges quer zur Fahrtrichtung mit einer Amplitude im Zentimeterbereich, insbesondere 1 - 5 cm, und einer Frequenz von wenigen Hertz, insbesondere etwa ein bis fünf Hertz. Für das Fahrzeug ergibt sich dann eine Fahrgeschwindigkeit von etwa 2 m/min., die eventuell noch an die Schadstellentiefe angepaßt werden kann.The horizontal vibrations of the pulling tool are advantageously carried out transversely to the direction of travel with an amplitude in the centimeter range, in particular 1-5 cm, and a frequency of a few hertz, in particular approximately one to five hertz. The vehicle then has a driving speed of about 2 m / min., Which can possibly be adapted to the depth of the damaged area.

Zu der genannten Schwingung kann eine zusätzliche Schwingung mit herkömmlichen Parametern, also einer Amplitude von Millimeter-Bruchteilen und einer Frequenz von über 70 Hertz überlagert werden, wobei diese zusätzliche Schwingung entweder horizontal oder vertikal erfolgen kann. Dadurch läßt sich die Verdichtungsqualität noch verbessern.An additional vibration with conventional parameters, that is to say an amplitude of millimeter fractions and a frequency of over 70 Hertz, can be superimposed on the aforementioned vibration, this additional vibration being able to take place either horizontally or vertically. As a result, the compression quality can still be improved.

Eine besonders vorteilhafte Ausgestaltung des Abziehwerkzeuges besteht darin, daß es eine konkav gewölbte Unterseite mit einem Krümmungsradius kleiner etwa zehn Zentimeter aufweist. Dabei hat sich überraschend herausgestellt, daß bei einer solchen Profilierung überstehende Splitteilchen und dergleichen aus der Belagoberfläche herausgerissen oder eingedrückt und Lücken durch kleine Teilchen verschlossen werden. Man erhält dadurch eine optimal glatte Fahrbahnoberfläche.A particularly advantageous embodiment of the removal tool is that it has a concave underside with a radius of curvature less than about ten centimeters. It has surprisingly been found that protruding split particles and the like are torn out or pressed in from the covering surface in such a profiling and gaps are closed by small particles. This gives you an optimally smooth road surface.

Um ein sauberes Egalisieren der reparierten Schadstellen mit den angrenzenden Bereichen sicherzustellen, empfiehlt es sich, daß das Abziehwerkzeug durch Gewichtsbelastung - in der Praxis etwa im Tonnenbereich - auf das Niveau der unbeschädigten Fahrbahndecke gedrückt wird.In order to ensure a clean leveling of the repaired damaged areas with the adjacent areas, it is recommended that the pulling tool is pressed to the level of the undamaged road surface by weight load - in practice, for example, in the ton range.

Für die konstruktive Ausbildung des Abziehwerkzeuges bieten sich dem Fachmann verschiedene Möglichkeiten. Es kann beispielsweise aus zwei stumpfwinklig nebeneinander angeordneten Werkzeugen bestehen, die das von ihnen abgeschabte Material nach außen oder nach innen befördern. Einfacher ist es aber meist, ein sich quer zum Fahrzeug erstreckendes Werkzeug vorzusehen und ihm eine Fördervorrichtung vorzuschalten, die das abgeschabte Material aufnimmt und - gegebenenfalls unter Erwärmung - der Ausgabevorrichtung oder einem Vorratsbehälter zuführt.The skilled person has various options for the constructive design of the removal tool. It can consist, for example, of two tools arranged side by side at an obtuse angle, which convey the material scraped off by them outwards or inwards. However, it is usually simpler to provide a tool extending transversely to the vehicle and to connect a conveyor device upstream of it, which picks up the scraped-off material and, if necessary with heating, feeds it to the dispensing device or a storage container.

Hinsichtlich der Ausbildung des Verdichtungswerkzeuges hat es sich als wichtig erwiesen, daß es aus mehreren, quer zur Fahrtrichtung nebeneinander angeordneten Verdichtungselementen besteht, die unabhängig voneinander Vertikalschwingungen mit einer Amplitude im Zentimeter-Bereich durchführen. Dadurch ist eine homogene Verdichtung, unabhängig von der jeweiligen Verdichtungswilligkeit der verschiedenen Schadstellen, sichergestellt. Unterstützt werden kann dies noch dadurch, daß die Verdichtungselemente in Vertikalrichtung elastisch an ihre Erreger angekoppelt sind. Ihr Antrieb kann durch Einzelerreger erfolgen. Besonders zweckmäßig ist es aber, die Verdichtungselemente an benachbarte Kurbeln einer gemeinsamen Kurbelwelle anzulenken.With regard to the design of the compacting tool, it has proven to be important that it consists of several compacting elements arranged next to one another transversely to the direction of travel, which independently perform vertical vibrations with an amplitude in the centimeter range. This ensures homogeneous compaction, regardless of the respective compaction willingness of the various damaged areas. This can be supported by the fact that the compression elements are elastically coupled to their exciters in the vertical direction. They can be driven by single exciters. However, it is particularly expedient to link the compression elements to adjacent cranks of a common crankshaft.

Zur Niveauregulierung empfiehlt es sich, daß zumindest das Verdichtungswerkzeug und das Abziehwerkzeug, gegebenenfalls aber auch die Ausgabevorrichtung für das Füllmaterial in Vertikalrichtung verfahrbar am Fahrzeug gelagert sind und sich über seitliche Stützrollen an der intakten Fahrbahndecke oder an Schienen abstützen. Durch eine Hubvorrichtung können sie aus ihrer unteren Arbeitsposition in eine obere Ruheposition verfahren werden, damit das Fahrzeug zwischen den einzelnen Baustellen rasch verfahren werden kann. Dabei wird die Ausgabevorrichtung für das Füllmaterial durch einen Schließmechanismus im unteren Ausgabebereich verschlossen.For level control, it is recommended that at least the compacting tool and the pulling tool, but possibly also the dispensing device for the filling material, are mounted on the vehicle so that they can be moved in the vertical direction and are supported on the intact pavement or on rails via lateral support rollers. Using a lifting device, they can be moved from their lower working position to an upper resting position so that the vehicle can be moved quickly between the individual construction sites. The dispensing device for the filling material is closed by a locking mechanism in the lower dispensing area.

Man erkennt in Figur 1 ein lenkbares Reparaturfahrzeug 1, das an seinem Vorderbau 2 mehrere Flächen-Heizvorrichtungen 3, 4, Aufreißzähne 5 zum oberflächlichen Aufreißen der vorgewärmten, teilweise beschädigten Fahrbahndeckschicht, eine Ausgabevorrichtung 6 mit erhitztem Asphalt oder ähnlichem Füllmaterial, dahinter ein Verdichtungswerkzeug 7 und ein Abziehwerkzeug 8 aufweist. Im rückwärtigen Teil des Fahrzeuges ist der Antriebsmotor untergebracht, außerdem befindet sich dort ein Aufnahmeraum für Gasflaschen, die zur Versorgung der Heizvorrichtungen 3 und 4 dienen.One can see in FIG. 1 a steerable repair vehicle 1, which has on its front structure 2 several surface heating devices 3, 4, ripping teeth 5 for tearing open the preheated, partially damaged road surface layer, an output device 6 with heated asphalt or similar filling material, behind it a compaction tool 7 and has a removal tool 8. In the back Part of the vehicle is the drive motor, there is also a receiving space for gas bottles that serve to supply the heating devices 3 and 4.

Wie insbesondere die vergrößerten Darstellungen in Figur 2 und 3 zeigen, besteht die Ausgabevorrichtung 6 aus einem Vorratsbehälter, dessen Ausgabeöffnung 6a etwa auf dem Nivau der unbeschädigten Deckschicht oder knapp darüber geführt wird. Er trägt an seinem vorderen Ende einen Gleitschuh 6b, während seine Rückwand zumindest im unteren Bereich von einem höhenverstellbaren Abzieher 6c gebildet wird. Die Unterkante dieses Abziehers wird auf einen Abstand von einigen Zentimetern über dem Fahrbahnniveau eingestellt und definiert die Füllstoffmenge, die aus der Ausgabevorrichtung abfließt. Durch einen zeichnerisch nicht dargestellten Verschluß kann die Ausgabeöffnung 6a verschlossen werden.As shown in particular in the enlarged representations in FIGS. 2 and 3, the dispensing device 6 consists of a storage container, the dispensing opening 6a of which is guided approximately at the level of the undamaged cover layer or just above it. It carries a sliding shoe 6b at its front end, while its rear wall is formed at least in the lower area by a height-adjustable puller 6c. The lower edge of this puller is set at a distance of a few centimeters above the roadway level and defines the amount of filler that flows out of the dispenser. The dispensing opening 6a can be closed by a closure, not shown in the drawing.

Das dahinter folgende Verdichtungswerkzeug 7 besteht aus mehreren quer zur Fahrtrichtung nebeneinander angeordneten vertikal schwingenden Verdichtungselementen. Sie sind in ihrer Schwingungsamplitude unabhängig voneinander, so daß der Verdichtungseffekt unabhängig ist vom Niveau der Unterlage, also beispielsweise das in einem tiefen Schlagloch angesammelte Material tiefer nach unten gedrückt wird als über einer flachen Schadstelle. Es stellt sich also eine weitgehend homogene Verdichtungsqualität unabhängig von der Schadstell-Tiefe und -größe ein. Jedoch ist das Verdichtungswerkzeug so eingestellt, daß das verdichtete Material einen Überstand von wenigen Zentimetern über dem letzlich angestrebten Sollniveau aufweist.The following compression tool 7 consists of several vertically oscillating compression elements arranged next to one another transversely to the direction of travel. They are independent of one another in their vibration amplitude, so that the compaction effect is independent of the level of the base, for example the material accumulated in a deep pothole is pressed deeper than over a flat damaged area. This results in a largely homogeneous compaction quality regardless of the depth and size of the damaged area. However, the compacting tool is set so that the compacted material has a protrusion of a few centimeters above the target level ultimately sought.

Im Ausführungsbeispiel besteht das Verdichtungswerkzeug 7 aus vier nebeneinander angeordneten Rüttelplatten 7a, die doppelseitig über Federn 7b an ein Pleuel 7c angekoppelt sind und diese Pleuel schließlich von einer gemeinsamen Kurbelwelle 7d, die ein Schwungrad trägt, angetrieben werden. Die unteren Federn sind von Faltenbälgen umgeben, um sie vor Verschmutzung zu schützen. Selbstverständlich ist stattdessen aber auch eine andere konstruktive Ausbildung der Einzelschwinger möglich.In the exemplary embodiment, the compression tool 7 consists of four jogger plates 7a arranged side by side, which are coupled on both sides to a connecting rod 7c via springs 7b and these connecting rods are finally driven by a common crankshaft 7d which carries a flywheel. The lower springs are surrounded by bellows to protect them from dirt. Of course, a different design of the individual vibrators is also possible instead.

Hinter dem Verdichtungswerkzeug ist gegebenenfalls noch ein weiterer, höhenverstellbarer Abzieher 9 angeordnet. Er bildet zusammen mit zwei in Fahrtrichtung laufenden Seitenwänden 19 (vgl. Figur 4) sowie mit dem vorderen Abzieher 6c eine Art Rahmen, damit das Material länger in dem der Verdichtung ausgesetzten Bereich gehalten wird. Die Seitenwände 19 sind aber in ihrer Höhe unabhängig von den Abziehern 6c und 9 verstellbar, denn sie sollen auf dem intakten Boden gleiten. Dazu können Sie im unteren Bereich elastisch ausgebildet sein, damit sie sich an Fahrbahnunebenheiten anpassen können.A further, height-adjustable puller 9 is optionally arranged behind the compacting tool. Together with two side walls 19 running in the direction of travel (see FIG. 4) and with the front puller 6c, it forms a kind of frame so that the material is held longer in the area exposed to compression. However, the height of the side walls 19 can be adjusted independently of the pullers 6c and 9, because they should slide on the intact floor. For this purpose, they can be elastic in the lower area so that they can adapt to uneven road surfaces.

Das Verdichtungswerkzeug 7 sowie die beiden Seitenwände 19 sind in Vertikalrichtung verfahrbar am Fahrzeug 1 gelagert und stützen sich über seitliche Rollen 13 (vgl. Figur 4) auf der unbeschädigten Fahrbahnoberfläche oder auf entsprechenden Fahrschienen ab. Die Rollen 13 sind an Streben 14 montiert, die ihrerseits vertikal verfahrbar im Vorbau 2 angeordnet sind. Außerdem ist an den Streben 14 über elastische Elemente 15 das Verdichtungswerkzeug 7 gelagert. Unabhängig vom Verdichtungswerkzeug und den Seitenwänden sind auch die Abzieher 6c und 9 vertikal verfahrbar, um die gewünschte Schütthöhe einzustellen.The compacting tool 7 and the two side walls 19 are mounted on the vehicle 1 such that they can be moved in the vertical direction and are supported on the undamaged road surface or on corresponding rails via lateral rollers 13 (see FIG. 4). The rollers 13 are mounted on struts 14, which in turn are arranged vertically movable in the stem 2. In addition, the compression tool 7 is mounted on the struts 14 via elastic elements 15. Regardless of the compaction tool and the side walls, the pullers 6c and 9 can also be moved vertically in order to set the desired dumping height.

Am Ende des Fahrzeuges erkennt man die Ausbildung des Abziehwerkzeuges 8 in Form eines quer zur Fahrtrichtung angeordneten zylindrischen Rohres mit einem Durchmesser von vorzugsweise etwa zehn bis fünfzehn Zentimetern. Es tangiert mit seinem tiefsten Bereich das gewünschte Sollniveau, also das Niveau des unbeschädigten benachbarten Fahrbahnbereiches und führt quer zur Fahrtrichtung Horizontalschwingungen einer Amplitude von einigen Zentimetern und einer Frequenz von etwa drei Hertz durch. Dadurch wird der Überstand des aufgefüllten Materials abgeschält und gleichzeitig die neu gebildete Fahrbahnoberfläche unter bündigem Anschluß an die intakte Fahrbahn endverdichtet und geglättet. Sein Antrieb für die langsame Grundschwingung erfolgt zum Beispiel durch einen Exzenter oder einen Kurbeltrieb 10, vgl. Figur 3, wogegen für die höher frequente Oberschwingung ein Kreiserreger, ein gerichteter Schwinger oder dergleichen verwendet werden kann.At the end of the vehicle one can see the design of the pulling tool 8 in the form of a cylindrical tube arranged transversely to the direction of travel and having a diameter of preferably about ten to fifteen centimeters. With its deepest area, it affects the desired target level, i.e. the level of the undamaged adjacent lane area, and carries out horizontal vibrations transverse to the direction of travel with an amplitude of a few centimeters and a frequency of about three Hertz. As a result, the excess material is peeled off and, at the same time, the newly formed road surface is finally compacted and smoothed with a flush connection to the intact road. It is driven for the slow fundamental vibration, for example, by an eccentric or a crank mechanism 10, cf. Figure 3, whereas a circular exciter, a directional oscillator or the like can be used for the higher frequency harmonic.

Damit der von den Seitenwänden 19 und den Abziehern 6c und 9 gebildete Kasten nach hinten verlängert werden und über eine Rückwand 20 auch das Abziehwerkzeug 8 mit einschließen kann, sind die hinteren Wandteile mit der Rückwand 20 und dem Abziehwerkzeug 8 über eine elastische Vibrationsfuge 21 mit den vorderen Wandteilen 19 verbunden. Diese Vibrationsfuge ist so ausgelegt, daß sie die im Zentimeterbereich liegenden Horizontalschwingungen des Abziehwerkzeuges 8 und der ihm zugeordneten Wandteile aufzunehmen vermag. Dadurch können alle für die Reparatur notwendigen Elemente in einem seitlich geschlossenen Kasten untergebracht werden und der Austritt von nicht benötigtem Reparaturmaterial wird weitgehend unterbunden.So that the box formed by the side walls 19 and the pullers 6c and 9 can be extended to the rear and also include the pulling tool 8 via a rear wall 20, the rear wall parts with the rear wall 20 and the pulling tool 8 are connected via an elastic vibration joint 21 front wall parts 19 connected. This vibration joint is designed so that it is able to absorb the horizontal vibrations of the pull-off tool 8 and the wall parts assigned to it, which are in the centimeter range. As a result, all the elements required for the repair can be accommodated in a box which is closed on the side, and the escape of unnecessary repair material is largely prevented.

Gleichzeitig erlaubt es die Vibrationsfuge 21, den hinteren Bereich des Kastens mit dem Abziehwerkzeug 8 in Vertikalrichtung verfahrbar am Fahrzeug 1 zu lagern, indem sich dieser Bereich über beidseits laufende Rollen 16 auf der intakten Fahrbahnoberfläche abstützt. Zwischen dem Abziehwerkzeug 8 und den Rollen 16 ist zweckmäßig eine Höhenverstellung möglich. Die Rollen 16 müssen selbstverständlich von den Horizontalschwingungen des Abziehwerkzeuges abgekoppelt werden, beispielsweise durch eine Horizontalführung oder durch elastische Elemente. Dadurch ist sichergestellt, daß die Verdichtungs- und Abziehwerkzeuge in einem definierten Abstand zu der unter ihnen befindlichen Straßenoberfläche geführt und die zuvor vorhandenen Unebenheiten ideal ausgeglichen werden und das verdichtete Füllmaterial mit der unbeschädigten Straßenoberfläche fluchtet. Stattdessen kann das Abziehwerkzeug 8 ohne die Rollen 16 allein durch die Rollen 13 höhengeführt werden, wenn man die Vibrationsfuge entsprechend gestaltet.At the same time, the vibration joint 21 allows the rear region of the box to be mounted on the vehicle 1 so that it can be moved in the vertical direction by means of the pulling tool 8, in that this region is supported on the intact road surface by rollers 16 running on both sides. A height adjustment is expediently possible between the pulling tool 8 and the rollers 16. The rollers 16 must of course be decoupled from the horizontal vibrations of the puller, for example by a horizontal guide or by elastic elements. This ensures that the compaction and removal tools are guided at a defined distance from the road surface below them and that the previously existing unevenness is ideally compensated for and the compacted filler material is aligned with the undamaged road surface. Instead, the pulling tool 8 can be guided in height without the rollers 16 solely by the rollers 13 if the vibration joint is designed accordingly.

Überschüssiges Material und vom Abziehwerkzeug 8 abgeschabtes Material wird von einer Transportvorrichtung, gegebenenfalls unter gleichzeitiger Beheizung, in den Ausgabebehälter 6 zurückgefördert. Im Ausführungsbeispiel dient hierzu etwa eine parallel vor dem Abziehwerkzeug 8 angeordnete, umlaufende Förderschnecke 11. Sie fördert das Material zur einen Seite hin, wo es von einem ansteigenden Förderband 12 aufgenommen und in die Ausgabevorrichtung 6 entlassen wird.Excess material and material scraped off by the pull-off tool 8 are conveyed back into the dispensing container 6 by a transport device, possibly with simultaneous heating. In the exemplary embodiment, a rotating screw conveyor 11 arranged in front of the pulling tool 8 is used for this purpose. It conveys the material to one side, where it is picked up by a rising conveyor belt 12 and released into the output device 6.

Die Arbeitsbreite des Verdichtungswerkzeuges 7 wie auch des Abziehwerkzeuges 8 ist so gewählt, daß die üblicherweise vorkommenden Schlaglöcher etc. kleiner als die Arbeitsbreite sind. Auf jeden Fall müssen aber die seitlichen Stützrollen 13 und 16 auf der intakten Fahrbahnoberfläche abrollen, damit das richtige Fahrbahnniveau gewährleistet ist.The working width of the compacting tool 7 and of the pulling tool 8 is selected so that it is usually occurring potholes etc. are smaller than the working width. In any case, the side support rollers 13 and 16 must roll on the intact surface of the road so that the correct level of road is guaranteed.

Es liegt im Rahmen der Erfindung, die Erhitzungseinheit vom Fahrzeug zu trennen und stattdessen mit separaten Erhitzungseinheiten in einem eigenen Fahrzeug zu arbeiten, um die Manövrierfähigkeit zu verbessern.It is within the scope of the invention to separate the heating unit from the vehicle and instead to work with separate heating units in a separate vehicle in order to improve maneuverability.
