Description

Die Erfindung betrifft einen Einbauzug gemäß Oberbegriff des Patentanspruchs 1.The invention relates to a paving train according to the preamble of patent claim 1.

Bei dem aus JP 2002 322603 A bekannten Einbauzug fährt das selbstfahrende Sprühmodul zwangsweise mit eigenem Fahrer und einer dem Planum zugewandten Sprührampe am Sprüh-modul zwischen dem nachfahrenden Straßenfertiger und der vorausfahrenden Zuführeinrichtung, die aus Einbaugut liefernden Lastkraftwagen versorgt wird.At the JP 2002 322603 A Known paving moves the self-propelled spray module forcibly with its own driver and a planum facing the spray on the spray module between the trailing paver and the leading feeder, which is supplied from truck delivering truck.

Ein aus US 4 062 559 A bekannter Straßenfertiger ohne Sprüheinrichtung weist zum Zuführen von Einbaugut aus einem LKW in den Materialbunker des Straßenfertigers übliche Abdrückrollen am Vorderende des Chassis auf. Vor einem Zuführvorgang legen sich zunächst die Abdrückrollen an die Hinterradreifen des Lastkraftwagens an. Dann werden am Chassis des Straßenfertigers angeordnete Zugarme an den Hinterrädern selbst zum ziehenden Angriff gebracht, damit sich der Lastkraftwagen während des Zuführvorganges nicht mehr vom Straßenfertiger zu lösen vermag, weil eine kombinierte Schub- und Zugverbindung vorliegt.On off US 4 062 559 A known road finisher without sprayer has for feeding of building material from a truck in the material bunker of the paver usual Abdrückrollen on the front end of the chassis. Before a feeding process, first apply the Abdrückrollen to the rear tires of the truck. Then arranged on the chassis of the paver traction arms are brought to the rear wheels themselves to pulling attack, so that the truck is unable to solve during the Zuführvorganges from the paver, because a combined push and pull connection exists.

Bei dem aus AT-E-55 434 B bekannten Einbauzug ist die Sprühvorrichtung in die als Beschicker ausgebildete Zuführeinrichtung integriert, die das Einbaugut über die Sprührampe der Sprühvorrichtung hinweg zum Straßenfertiger fördert. Die Sprührampe bringt die Bitumenemulsion über die Arbeitsbreite der Einbaubohle auf das Planum auf, wobei die Fahrspuren des Straßenfertigers ausgespart werden. Der Straßenfertiger ist mit hinter dem Fahrwerk integrierten Sprührampen versehen, die das Planum hinter den Fahrspuren und vor der Querverteilvorrichtung des Straßenfertigers mit Bitumenemulsion besprühen. Der Beschicker mit der integrierten Sprühvorrichtung ist wie auch der Straßenfertiger mit den integrierten Sprührampen jeweils eine Spezialkonstruktion und deshalb baulich aufwendig und teuer. In Einsatzfällen, in denen keine Bitumenemulsion verarbeitet zu werden braucht, schleppt der Beschicker den unnötigen Ballast der Sprühvorrichtung, und sind auch die Sprührampen am Straßenfertiger unnötiger Ballast. Die Sprühvorrichtung und die Sprührampen am Straßenfertiger verschmutzen bei der Einbauarbeit und fordern deshalb nach Arbeitsende aufwendige Reinigungsarbeiten, unabhängig davon, ob mit Bitumenemulsion gearbeitet wird, oder nicht.At the AT-E-55 434 B Known paving train, the sprayer is integrated into the feeder designed as a feeder, which promotes the built-in over the spraying ramp of the spraying device away to the paver. The spray ramp brings the bitumen emulsion over the working width of the screed on the planum, the lanes of the paver are spared. The paver is equipped with spray turrets integrated behind the landing gear which spray bituminous emulsion behind the lanes and in front of the paver's transverse distributor. The feeder with the integrated spraying device, as well as the road paver with the integrated spraying ramps, are each a special construction and therefore structurally complex and expensive. In applications in which no bitumen emulsion needs to be processed, the feeder tows the unnecessary ballast of the sprayer, and also the sprayers on the paver are unnecessary ballast. The spraying device and the spraying ramps on the road paver become dirty during the installation work and therefore require elaborate cleaning work after the end of the working day, irrespective of whether working with bitumen emulsion or not.

Der aus US 5 279 500 A bekannte Straßenfertiger ist mit einer voll integrierten Sprühvorrichtung einschließlich zur Bevorratung und zum Ausbringen erforderlicher Komponenten ausgestattet. Die Sprührampe weist Düsen auf, die zum Dosieren des Auftrags mit getakteten Verschlussorganen zusammenarbeiten. Die Sprührampe kann um eine quer zur Arbeitsfahrtrichtung liegende Achse hin- und hergeschwenkt werden und ovale oder rechteckige Sprühbilder erzeugen.The out US 5,279,500 known road paver is equipped with a fully integrated spray device including for stocking and for dispensing necessary components. The spray ramp has nozzles that work together to meter the job with clocked shutters. The spray ramp can be swiveled back and forth about an axis transverse to the direction of travel and produce oval or rectangular spray patterns.

Aus DE 39 42 496 A ist eine Einrichtung zum dosierten Auftragen eines flüssigen Bindemittels, insbesondere Bitumen, auf eine Straßenoberfläche bekannt, die auf einem fahrbaren Chassis angeordnet ist und Komponenten zur Bevorratung und zum Ausbringen einschließlich einer Sprührampe aufweist. Die Dosierung erfolgt, indem die versprühte Menge nach dem Prinzip der Massendurchflussmessung bei gleichzeitiger Messung der Corioliskraft gemessen wird. Diese bekannte Einrichtung wird auf althergebrachte Weise eingesetzt, um das Planum in einem separaten Arbeitsgang zu besprühen, ehe nach dem Abbinden später eine Deckenschicht eingebaut wird.Out DE 39 42 496 A a device for the metered application of a liquid binder, in particular bitumen, on a road surface is known, which is arranged on a mobile chassis and has components for storage and for deployment including a spray ramp. The metering takes place by measuring the sprayed quantity according to the principle of mass flow measurement with simultaneous measurement of the Coriolis force becomes. This known device is used in a traditional way to spray the planum in a separate operation before a ceiling layer is installed later after setting.

In neuerer Zeit haben sich Einbauzüge bewährt, die wenigstens eine Deckenschicht kontinuierlich und mit optimal hoher Einbaugeschwindigkeit einbauen lassen, weil der Einbau durch die Anlieferung und Zuführung des Einbauguts nicht beeinträchtigt wird. Dieses Konzept beruht darauf, den Straßenfertiger mit dem Einbaugut von einem vorausfahrenden Beschicker (Shuttle Buggy) aus zu versorgen, der von intermittierend hin- und wegfahrenden Lastkraftwagen mit Einbaugut versorgt wird und sozusagen einen Puffer mit großem Speichervolumen bildet. Obwohl sich auch die Technologie beim Aufbringen einer Bitumenemulsion als Haftschicht für die darauf einzubauende Deckenschicht dahingehend verbessert hat, dass die Bitumenemulsion erst unmittelbar vor dem Aufbringen der Deckenschicht aufgesprüht wird ( EP 049 260 B ), was auch bei dem Einbauzug gemäß AT-E-55 434 B realisiert wird, wird bisher entweder ein Spezialbeschicker mit integrierter Sprühvorrichtung und ein Spezial-Straßenfertiger mit integrierten Sprührampen für die Fahrspuren verwendet, oder ein Standardbeschicker und ein Spezial-Straßenfertiger mit integrierter Sprühvorrichtung ( DE 41 01 417 B ). Da jedoch Firmen, die Einbauarbeiten sowohl mit einer Haftschicht als auch ohne Haftschicht durchzuführen haben, bei Einbauarbeiten ohne Haftschicht den unnötigen Ballast der Spezialmaschinen bzw. deren deutlich höhere Kosten als Nachteil empfinden, jedoch auch fallweise Einbauarbeiten mit einer Haftschicht durchzuführen haben, besteht erheblicher Bedarf, nach einem Einbauzugkonzept mit einem Standardbeschicker und einem Standard-Straßenfertiger und der wahlweisen Option, einfach und kostengünstig auch eine Haftschicht aufbringen zu können. Dies wäre zur Verbesserung der Maschinenauslastung und zur Erweiterung des Einsatzspektrums ohne unnötigen Mehrballast oder unnötige Mehr-Reinigungsarbeiten außerordentlich wünschenswert, und zwar gepaart mit einer Verringerung der Einstandskosten für die Maschinenbeschaffung.In recent times, paving trains have proven that can install at least one ceiling layer continuously and with optimal high speed installation, because the installation is not affected by the delivery and feeding of the paving. This concept is based on supplying the paver with the built-in material from a preceding feeder (shuttle buggy), which is supplied with built-in material by intermittently moving lorries and thus forms a buffer with a large storage volume. Although the technology has improved when applying a bitumen emulsion as an adhesive layer for the ceiling layer to be installed thereon in such a way that the bitumen emulsion is sprayed on just before the application of the top layer ( EP 049 260 B ), which also according to the paving train AT-E-55 434 B So far, either a special feeder with integrated sprayer and a special road paver with integrated spray lanes for the lanes, or a standard feeder and a special paver with integrated spraying device ( DE 41 01 417 B ). However, since companies that perform installation work both with an adhesive layer and without an adhesive layer, feel the unnecessary ballast of special machines or their significantly higher costs as a disadvantage in installation work without adhesive layer, but also occasionally have to perform installation work with an adhesive layer, there is considerable need according to a built-in train concept with a standard feeder and a standard paver and the optional option of being able to easily and inexpensively apply an adhesive layer. This would be extremely desirable for improving machine utilization and extending the range of use without unnecessary multi-ballast or unnecessary multi-cleaning work, coupled with a reduction in the cost of procurement for machine procurement.

Der Erfindung liegt die Aufgabe zugrunde, einen Einbauzug der eingangs genannten Art anzugeben, der es als modular aufgebautes System ermöglicht, mit Standardmaschinen und einen kostengünstigen Sprühmodul und dadurch verringerten Einstandskosten Einbauarbeiten mit und ohne Bitumenemulsion-Haftschicht durchzuführen.The invention has for its object to provide a paving train of the type mentioned, which makes it possible as a modular system to perform with standard machines and a cost-effective spray module and thereby reduced cost installation work with and without bitumen emulsion adhesive layer.

Die gestellte Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst.The stated object is achieved with the features of claim 1.

Für Einbauarbeiten mit der Haftschicht wird das Sprühmodul zwischen der z.B. als Standardbeschicker ausgebildeten Zuführeinrichtung und dem Standard-Straßenfertiger installiert, um die Bitumenemulsion-Haftschicht vor dem Straßenfertiger auf das Planum aufzubringen. Weder am Standardbeschicker noch am Standard-Straßenfertiger sind dazu aufwendige Umrüstarbeiten erforderlich. Wird keine Haftschicht eingebaut, dann wird das Sprühmodul weggelassen und herkömmlich gearbeitet. Das Sprühmodul ist eine kostengünstige universelle und effiziente Zusatzmaschine als modularer Baustein des Einbauzugs. Es ist entweder zwischen dem Sprüh-modul ohne eigenen Fahrantrieb und dem Beschicker bzw. der Zuführeinrichtung eine Schleppverbindung vorgesehen, die zum Entfernen des Sprühmoduls lösbar ist, jedoch das Sprühmodul zwangsweise mit dem Beschicker fährt, oder ist zwischen dem keinen eigenen Fahrantrieb aufweisenden Sprühmodul und dem Straßenfertiger eine Schubverbindung vorgesehen, so dass der Straßenfertiger das Sprühmodul mit vorbestimmtem Abstand schiebt. Dabei ist zwischen dem Sprühmodul und dem Standard-Straßenfertiger eine Leistungs- und Steuersignalübertragungs-Verbindung vorgesehen, so dass das Sprühmodul mit Leistung beispielsweise zum Beheizen und Ausbringen und Dosieren der Bitumenemulsion versorgt wird, oder entsprechend gesteuert wird. Dies ist eine besonders kostengünstige Ausführungsform des Sprühmoduls. Am Straßenfertiger vorhandene Steuerungs- und Leistungssysteme können die zusätzlichen, sich zum Betrieb des Sprühmoduls ergebenden Aufgaben problemlos erfüllen. Ferner ist eine Steuereinrichtung vorgesehen, die die Sprühbreite des Sprühmoduls synchron an die Arbeitsbreite der Einbaubohle anpasst. Hierfür wird die Leistungs- und/oder Steuerübertragungs-Verbindung eingesetzt.For installation work with the adhesive layer, the spray module is installed between, for example, the feeder designed as a standard feeder and the standard paver to apply the bitumen emulsion adhesive layer to the paver in front of the paver. Neither the standard loader nor the standard paver requires extensive retooling. If no adhesive layer is installed, then the spray module is omitted and worked conventionally. The spray module is a cost-effective universal and efficient auxiliary machine as a modular component of the paving train. It is provided either between the spray module without its own drive and the feeder or the feeder a towing connection, which is detachable for removing the spray module, but forcibly moves the spray module with the feeder, or is between the no separate traction drive having spray module and the paver provided a thrust connection so that the paver pushes the spray module with a predetermined distance. In this case, a power and control signal transmission connection is provided between the spray module and the standard paver, so that the spray module is supplied with power, for example for heating and dispensing and dosing of the bitumen emulsion, or is controlled accordingly. This is a particularly cost-effective embodiment of the spray module. On the paver existing control and power systems can easily meet the additional, resulting in the operation of the spray module tasks. Furthermore, a control device is provided, which adjusts the spray width of the spray module synchronously to the working width of the screed. For this purpose, the power and / or control transmission connection is used.

Bei einer weiteren Ausführungsform befindet sich das Sprühmodul unterhalb der Fördervorrichtung, die das Einbaugut vom Beschicker zum Straßenfertiger liefert, so dass der Einbauguttransport nicht beeinträchtigt wird. Vorzugsweise hat der Sprühmodul eine Bauhöhe niedriger als eine Auskraghöhe eines Fördervorrichtungs-Traggestells des Beschickers, so dass das Sprüh-modul sozusagen in Arbeitsfahrtrichtung mit dem Beschicker überlappend gefahren wird.In a further embodiment, the spray module is located below the conveying device, which delivers the built-in material from the feeder to the paver, so that the chute transport is not impaired. Preferably, the spray module has a height lower than a Auskraghöhe a conveyor support frame of the feeder, so that the spray module is driven so to speak overlapping in the working direction with the feeder.

Schließlich ist es zweckmäßig, wenn am Straßenfertiger hinter dem Fahrwerk wenigstens eine Sprührampe zum Ausbringen von Bitumenemulsion nur auf die Fahrspuren des Fahrwerks abnehmbar angebracht wird, die vom Sprühmodul versorgbar und steuerbar ist. Diese Sprührampe, zweckmäßig zwei Sprührampen, ist so konzipiert, dass sie sich an einem Standard-Straßenfertiger anbringen und leicht abnehmen lässt. Die Versorgung und/oder Steuerung erfolgt dann über eine Leitung oder Schlauchleitung vom Sprühmodul aus. Wird keine Haftschicht aufgebracht, dann braucht auch die Sprührampe nicht an den Straßenfertiger angebaut zu werden, oder wird die angebaute Sprührampe einfach abgenommen und beiseite gelegt oder am Straßenfertiger oder Beschicker mittransportiert, um nach Arbeitsende nicht gereinigt werden zu müssen.Finally, it is expedient if the paver behind the chassis at least one sprayer for discharging bitumen emulsion is removably mounted only on the lanes of the chassis, which can be supplied and controlled by the spray module. This spray ramp, conveniently two spray lances, is designed to attach to a standard paver and be easily removed. The supply and / or control then takes place via a line or hose line from the spray module. If no adhesive layer is applied, then the spray ramp does not need to be attached to the paver, or the attached spray ramp is simply removed and set aside or transported along the paver or feeder to not have to be cleaned after work.

Anhand der Zeichnung, die in Fig. 1 eine schematische Seitenansicht eines Einbauzugs ist, wird eine Ausführungsform des Erfindungsgegenstandes erläutert.Based on the drawing, in Fig. 1 is a schematic side view of a paving train, an embodiment of the subject invention is explained.

Ein in Fig. 1 in einer schematischen Seitenansicht gezeigter Einbauzug E dient entweder zum Einbauen einer bituminösen Deckenschicht (wie gezeigt) auf eine Haftschicht H aus einer Bitumenemulsion auf ein Planum P, oder zum Einbauen wenigstens einer beispielsweise bituminösen Deckenschicht ohne Haftschicht H direkt auf das Planum P (nicht gezeigt, sondern nur später erläutert).An in Fig. 1 In a schematic side view shown paving E is used either for incorporation of a bituminous ceiling layer (as shown) on an adhesive layer H from a bitumen emulsion on a subgrade P, or for incorporating at least one example bituminous ceiling layer without adhesive layer H directly on the subgrade P (not shown, but only explained later).

Der Einbauzug E umfasst einen Standard-Straßenfertiger F mit einer geschleppten Einbaubohle 1 (nämlich einer Ausziehbohle mit gesteuert veränderbarer Arbeitsbreite) zum Einbauen der Deckenschicht aus beispielsweise bituminösem Einbaugut in einer Arbeitsfahrtrichtung R, eine vor dem Standard-Straßenfertiger F auf dem Planum P fahrende Zuführeinrichtung B für Einbaugut, z.B. einen sogeannnten Standardbeschicker, sowie ein zwischen der Zuführeinrichtung B und dem Standard-Straßenfertiger F auf dem Planum P fahrendes Sprüh-modul M zum Aufbringen der Haftschicht H.The paving E comprises a standard paver F with a towed screed 1 (namely, a pull-out screed with controlled variable working width) for installing the top layer of example bituminous material in a working direction R, one before the standard paver F on the Planum P moving feeder B for building material, eg a so-called standard feeder, and a between the feeder B and the standard road paver F on the Planum P driving spray module M for applying the adhesive layer H.

Die Zuführeinrichtung B besitzt ein Fahrwerk 2, z.B. ein Raupenfahrwerk, ein Chassis 3, und einen vorderseitigen, auf dem Chassis 3 angeordneten Gutbunker 4, der beispielsweise von intermittierend heran- und wegfahrenden Lastkraftwagen (nicht gezeigt) mit Einbaugut befüllt wird. Von dem Gutbunker 4 erstreckt sich eine schräg nach hinten oben ansteigende Fördervorrichtung 5 über den Zwischenraum zu einem Gutbunker 11 des Standard-Straßenfertigers F. Ein beispielsweise kippbares Schüttende 7 bildet das Ende der Fördervorrichtung 5. Die Fördervorrichtung 5 ist auf einem Traggestell 6 zweckmäßig verstellbar installiert. Das hintere Ende des Traggestells 6 kragt nach hinten frei aus.The feeder B has a chassis 2, such as a crawler, a Chassis 3, and a front, arranged on the chassis 3 Gutbunker 4, which is filled, for example, by intermittently approaching and moving away trucks (not shown) with built-in. From the goods bunker 4, a conveyor device 5 rising obliquely rearwardly upwards extends over the intermediate space to a bunker 11 of the standard road paver F. An example of a dumpable discharge end 7 forms the end of the conveyor device 5. The conveyor device 5 is expediently adjustably mounted on a support frame 6 , The rear end of the support frame 6 projects freely backwards.

Der Standard-Straßenfertiger F weist ein Fahrwerk 8 auf, beispielsweise ein Raupenfahrwerk, und fährt in zwei Fahrspuren auf dem Planum P. Der Standard-Straßenfertiger F besitzt eine Primärantriebsquelle 9, beispielsweise einen Dieselmotor, einen Führerstand 10 und eine vom Gutbunker 11 bis zum hinteren Ende des Chassis des Standard-Straßenfertigers F verlaufende Förderstrecke 26, die das Einbaugut vor einer Querverteilvorrichtung 12 auf das Planum P bzw. die Haftschicht H abwirft.The standard paver F has a chassis 8, such as a crawler chassis, and travels in two lanes on the ground P. The standard paver F has a primary drive source 9, such as a diesel engine, a cab 10 and one from Gutbunker 11 to the rear End of the chassis of the standard paver F extending conveyor line 26, which drops the deposit in front of a transverse distribution device 12 on the subgrade P or the adhesive layer H.

Das Sprühmodul M besitzt ein Chassis 13, das auf einem eigenen Fahrwerk 14 auf dem Planum P rollt.The spray module M has a chassis 13, which rolls on its own chassis 14 on the planum P.

Das Sprühmodul M enthält ferner notwendige Komponenten 16 zur Bevorratung, Ausbringung und Dosierung der Bitumenelmusion mittels einer vor dem Vorderende des Standard-Straßenfertigers am Sprühmodul M angeordneten Sprührampe 17. Die Sprührampe 17 kann höhenverstellbar sein, oder sogar mittels einer Anlenkung 18 zyklisch bewegt werden. An der breitenverstellbar ausgebildeten Sprührampe 17 sind nicht dargestellte Sprühdüsen angeordnet, die die jeweils an der Einbaubohle 1 eingestellte Arbeitsbreite des Standard-Straßenfertigers besprühen, ausgenommen die zwei Fahrspuren des Fahrwerks 8 des Standard-Straßenfertigers F. Gegebenenfalls erfolgt eine Ansteuerung über nicht gezeigte Kabelstränge oder über eine drahtlose Übertragung von der Zuführvorrichtung B und/oder vom Standard-Straßenfertiger F.The spray module M also contains necessary components 16 for storing, applying and metering the bitumen emulsion by means of a spraying lamp 17 arranged in front of the front end of the standard road paver on the spraying module M. The spraying ramp 17 can be height-adjustable, or even cyclically moved by means of a linkage 18. Spray nozzles, not shown, are arranged on the width-adjustable spraying ramp 17, spraying the working width of the standard road paver set on the screed 1, with the exception of the two lanes of the chassis 8 of the standard paver F. Optionally, an activation takes place via cable strands (not shown) or above wireless transmission from the feeder B and / or the standard paver F.

Es sind Leistungs- und/oder Steuersignal-Übertragungsverbindungen 15 und/oder 21 zum Standard-Straßenfertiger F installiert, um Sprühmodul M mit Leistung und/oder Steuersignalen zu versorgen. Eine gemeinsame Arbeitsbreiten-Steuereinrichtung 26 am Straßenfertiger F ist vorgesehen, um die Sprühbreite des Sprühmoduls M synchron an die Arbeitsbreite der Einbaubohle 1 anzupassen, z.B. über die Verbindung 21.Power and / or control signal transmission links 15 and / or 21 to the standard paver F are installed to provide power and / or control signals to spray module M. A common working width control device 26 on the paver F is provided to adjust the spray width of the spray module M synchronously to the working width of the screed 1, e.g. over the connection 21.

Erfindungsgemäß besitzt das Sprühmodul M keinen eigenen Fahrantrieb. Vielmehr ist entweder eine Schleppverbindung 20 zwischen dem Sprühmodul M und der Zuführeinrichtung B oder eine Schubverbindung 21 zwischen dem Sprühmodul M und dem Standard-Straßenfertiger F eingebaut, die leicht lösbar ist, um das Sprühmodul entfernen zu können. Die Schleppverbindung 20 ist beispielsweise am Traggestell 6 der Zuführeinrichtung B lösbar angelenkt.According to the invention, the spray module M does not have its own drive. Rather, either a drag connection 20 between the spray module M and the feeder B or a thrust connection 21 between the spray module M and the standard paver F is installed, which is easily solvable to remove the spray module can. The drag connection 20 is, for example, releasably articulated on the support frame 6 of the feed device B.

Da das Sprühmodul M die zwei Fahrspuren des Fahrwerks 8 des Standard-Straßenfertigers auf dem Planum 8 nicht besprüht, ist eine oder sind zwei Sprührampen 23 am Standard-Straßenfertiger F abnehmbar installiert, und zwar zwischen dem Fahrwerk 8 und der Querverteilvorrichtung 12, um die Fahrspuren hinter dem Fahrwerk 8 mit Bitumenemulsion zu besprühen. Diese Sprührampe(n) 23 kann (können) über eine wegnehmbare Versorgungsleitung 22 vom Sprühmodul M versorgt und/oder gesteuert werden.Since the spray module M does not spray the two lanes of the chassis 8 of the standard paver on the subgrade 8, one or two spray ramps 23 are detachably installed on the standard paver F between the chassis 8 and the lateral distribution device 12 around the lanes behind the chassis 8 with bitumen emulsion to spray. This spray ramp (s) 23 can (can) be supplied and / or controlled via a removable supply line 22 from the spray module M.

Bei einer zweckmäßigen Ausführungsform hat das Sprühmodul M, zumindest im vorderen Endbereich, eine Bauhöhe, die es gestattet, dass das Sprühmodul M unter dem auskragenden Ende des Traggestells 6 fährt und so zum Vorderende des Standard-Straßenfertigers F einen größeren Abstand einhält.In an expedient embodiment, the spray module M, at least in the front end region, a height that allows the spray module M moves under the projecting end of the support frame 6 and thus maintains a greater distance to the front end of the standard paver F.

Es kann im Übrigen eine Abstands- und/oder Geschwindigkeitsregelvorrichtung vorgesehen sein (nicht gezeigt), damit die Zuführeinrichtung B und der Standard-Straßenfertiger F mit einem vorbestimmten Abstand und mit gleichen Geschwindigkeiten fahren.Incidentally, a distance and / or speed control device may be provided (not shown) for the feeder B and the standard paver F to travel at a predetermined distance and at equal speeds.

In Einbaufahrt des Einbauzugs E wird Einbaugut aus dem Gutbunker 4 über die Fördervorrichtung 5 in den Gutbunker 11 transferiert, und über die Förderstrecke 26 vor der Querverteilvorrichtung 12 abgeworfen. Die Querverteilvorrichtung 12 verteilt die Einbaugutvorlage für die Einbaubohle 1, die die Deckenschicht einbaut und gegebenenfalls verdichtet. Das Sprühmodul M bringt die Bitumenemulsion als Haftschicht H auf das Planum P auf, wobei die zwei Fahrspuren erst durch die Sprührampen 23 vor dem herabfallenden Einbaugut besprüht werden.In Einbauffahrt the paving train E Einbaugut is transferred from the Gutbunker 4 via the conveyor device 5 in the Gutbunker 11, and dropped over the conveyor line 26 in front of the transverse distribution device 12. The transverse distribution device 12 distributes the built-in material template for the screed 1, which incorporates the ceiling layer and optionally compacted. The spray module M brings the bitumen emulsion as adhesive layer H on the planum P, wherein the two lanes are first sprayed by the spraying ramps 23 in front of the falling-in building material.

Beim Einbau einer Deckenschicht ohne Haftschicht H wird das Sprühmodul M entfernt, und werden, zweckmäßigerweise, auch die Sprührampen 23 abgenommen. Dabei wird die Schleppverbindung 20 bzw. Schubverbindung 21 gelöst, und das Sprühmodul weggeschoben oder weggeschleppt.When installing a ceiling layer without adhesive layer H, the spray module M is removed, and, expediently, the spraying ramps 23 are removed. In this case, the drag connection 20 or thrust connection 21 is released, and the spray module pushed away or dragged away.
