Description

Die Erfindung bezieht sich auf ein Gerät zum Unterhalten von asphaltierten Strassen oder Wegen, insbesondere zum Auftrage eines bituminösen Bindemittels aus einem unter Druck stehenden Behälter und einem Splittbehälter mit zu Auslassöffnungen hin geneigter Bodenplatte auf einem mit zumindest einer Fahrachse versehenen Rahmen, wobei hinter der hinteren Fahrachse und unterhalb des Splittbehälters in Fahrtrichtung vor einem Splittentnahmetrichter mit zumindest einer über einen Handhebel einstellbaren Auslassöffnung Düsen zum Bitumenverteilen angeordnet sind, welche einzeln oder gruppenförmig über die Breite des Gerätes verteilt sind und mit den ebenfalls über die Breite des Gerätes in gleicher Weise verteilt angeordneten und getrennt voneinander bedienbaren Auslassöffnungen korrespondieren, und wobei hinter dem Splittentnahmetrichter eine Plattform vorgesehen ist.The invention relates to a device for maintaining asphalt roads or paths, in particular for applying a bituminous binder from a pressurized container and a grit container with a base plate inclined towards outlet openings on a frame provided with at least one driving axis, behind the rear driving axis and below the grit container in the direction of travel in front of a grit removal funnel with at least one outlet opening that can be adjusted via a hand lever, nozzles for bitumen distribution are arranged, which are distributed individually or in groups across the width of the device and are also arranged and separated in the same way across the width of the device outlet openings that can be operated from one another correspond, and a platform is provided behind the chip removal funnel.

Infolge der Motorisierung sind Asphaltdecken auf Strassen und Wegen inzwischen weit verbreitet. Nebenstrassen, Fahrwege im forst- und landwirtschaftlichen Bereich sowie Wirtschaftswege haben ebenso wie Landstrassen niederer Ordnung Asphalt als staubfreien Belag erhalten. Ein Problem für diejenigen, die diese Strassen und Wege zu unterhalten haben, stellt die Notwendigkeit dar, diesen staubfreien Belag ständig ausbessern und beispielsweise nach Frost oder Wasserschäden sowie nach Belastungsschäden oder nach Verlegen von unterirdischen Leitungen wieder herrichten oder ergänzen zu müssen. Diese entsprechenden Arbeiten sind äusserst kostenintensiv.As a result of the motorization, asphalt surfaces are now widely used on roads and paths. Secondary roads, driveways in the forestry and agricultural sector, as well as commercial roads, as well as lower-order country roads, have been given asphalt as a dust-free covering. A problem for those who have to maintain these streets and paths is the need to constantly repair this dust-free covering and to repair or replace it, for example after frost or water damage as well as after damage due to loading or after laying underground pipes. This corresponding work is extremely cost-intensive.

Es gibt verschiedenartige Geräte für das Verspritzen von Bitumen, die von Hand zu bedienen sind, und auf diese frischen Bindemittel wird Rohsplitt ebenfalls von Hand aus einem offenen niedrigen Wagen auf die versprühte Bitumenschicht mittels Schippen ausgebreitet. Hierfür sind üblicherweise für ein von einem Mann bedientes Spritzgerät zwei weitere Teerwerker erforderlich, um Splitt auszubreiten. Die richtige Mengenzumessung ist hierbei dem Geschick der Teerwerker überlassen.There are various types of bitumen spraying equipment that can be operated by hand, and these fresh binders are also used to spread raw chippings by hand from an open, low trolley onto the sprayed bitumen layer by means of shovels. This usually requires two more tar workers for a sprayer operated by a man to spread grit. The correct quantity metering is left to the skill of the tar workers.

Aus US-A-1 613 051 ist ein Gerät bekannt, das zum Unterhalten von asphaltierten Strassen oder Wegen dient. Dabei wird ein bituminöses Bindemittel aus einem unter Druck stehenden Behälter und einem Splittbehälter, die sich auf einem mit zumindest einer Fahrachse versehenen Rahmen befinden, aufgetragen, wobei hinter der hinteren Fahrachse und unterhalb des Splittbehälters Düsen zum Bitumenverteilen angeordnet sind und dahinter eine Plattform vorgesehen ist. Ein derartiges gerät dient zur Automatisierung der zuvor beschriebenen Asphaltierarbeiten. Allerdings ist das Gerät so beschaffen, dass über die gesamte Spurbreite der Fahrachse Splitt auf die zu asphaltierende Strasse oder den zu asphaltierenden Weg gestreut wird. Ein derartiges Gerät ist zwar hilfreich zum Aufbringen einer geschlossenen Asphaltdecke, ist allerdings nicht geeignet zum Ausbessern von Spurrillen oder Bankettekanten, weswegen diese Arbeiten häufig wieder auf die zuvor beschriebene manuelle Weise verrichtet werden. Darüberhinaus wird der aufzubringende Splitt mittels eines komplizierten Austragmechanismus, der aus ein Förderband mit separatem Antriebsmotor besteht, aus dem Splittvorratsbehälter ausgetragen. Durch das zusätzliche Transportband wird bei dem Austragevorgang ein zusätzliches Totzeitglied geschaffen, das heisst, beim Beginn des Asphaltierens ergibt sich eine Vorlaufzeit vom Austreten des Splitts aus dem Vorratsbehälter bis zum Ausstreuen des Splitts auf die Strasse und beim Beenden des Asphaltiervorganges bleibt bei Verschliessen des Vorratsbehälters Splitt unkontrolliert auf dem Transportband liegen.From US-A-1 613 051 a device is known which is used to maintain paved roads or paths. A bituminous binder consisting of a pressurized container and a grit container, which are located on a frame provided with at least one travel axis, is applied, nozzles for bitumen distribution are arranged behind the rear travel axis and below the grit container and a platform is provided behind it. Such a device is used to automate the previously described asphalting work. However, the device is designed in such a way that grit is scattered over the entire track width of the driving axle onto the road to be paved or the road to be paved. Such a device is helpful for applying a closed asphalt surface, but is not suitable for repairing ruts or banquet edges, which is why this work is often carried out again in the manual manner described above. In addition, the grit to be applied is discharged from the grit storage container by means of a complicated discharge mechanism, which consists of a conveyor belt with a separate drive motor. The additional conveyor belt creates an additional dead time element during the discharge process, which means that at the start of the asphalting process, there is a lead time from the discharge of the chippings from the storage container to the spreading of the chippings on the road and when the asphalting process is ended, the chippings remain closed when the storage container is closed lying on the conveyor belt in an uncontrolled manner.

Auch aus der FR-A-856461 ist ein Gerät der eingangs genannten Gattung bekannt, bei dem Düsen und Splittentnahmetrichter über die gesamte Breite des Gerätes angeordnet sind. Zum Austragen des Splitts aus dem Vorratsbehälter dient eine Austragsrolle, die sich über die gesamte Fahrzeugbreite erstreckt und von einem zusätzlich anzubringenden separaten Motor angetrieben wird. Eine derartige Austragsvorrichtung ist aufwendig und störanfällig.From FR-A-856461 a device of the type mentioned is known, in which nozzles and chip removal funnels are arranged over the entire width of the device. A discharge roller, which extends over the entire width of the vehicle and is driven by a separate motor to be attached, is used to discharge the chippings from the storage container. Such a discharge device is complex and prone to failure.

Es ist Aufgabe der vorliegenden Erfindung, ein Gerät für den Unterhalt von asphaltierten Wegen und Strassen verfügbar zu machen, welches einerseits einen einfach ausgebauten Austragmechanismus aus dem Splittbehälter aufweist und andererseits eine einfache spezifische Ausbesserung von Spurrillen und Bankettekanten ermöglicht.It is an object of the present invention to provide a device for the maintenance of asphalt paths and roads, which on the one hand has a simply dismantled discharge mechanism from the grit container and on the other hand enables simple specific repair of track grooves and banquet edges.

Erfindungsgemäss wird zur Lösung dieser Aufgabe ein gattungsgemässes Gerät derart weitergebildet, dass die Bodenplatte des Splittbehälters aus zwei Teilplatten besteht, wobei die erste Teilplatte in einem flachen Winkel gegenüber der Horizontalen geneigt ist, die sich zur zumindest einen Auslassöffnung des Behälters hin anschliessende zweite Teilplatte in einem sehr steilen Winkel geneigt ist und diese zweite Teilplatte mit einer oder mehreren an der Rückwand des Splittbehälters drehbar angelenkten Klappen, die dieser zweiten Teilplatte gegenüberliegen und über einen Handhebel einstellbar sind, einen länglichen Splittentnahmetrichter derart bildet, dass die zumindest eine zur Dosierung einer Splittmenge dienende Auslassöffnung durch die zum Boden hingerichteten Randbereiche der zweiten Teilplatte der Bodenplatte und der zumindest einen beweglichen Klappe gebildet wird.According to the invention, a generic device is developed in order to achieve this object in such a way that the base plate of the grit container consists of two partial plates, the first partial plate being inclined at a flat angle to the horizontal, the second partial plate adjoining the at least one outlet opening of the container in one is inclined at a very steep angle and this second partial plate with one or more flaps hinged to the rear wall of the chippings container, which are opposite this second partial plate and can be adjusted via a hand lever, forms an elongated grit removal funnel in such a way that the at least one outlet opening serving for metering a quantity of grit is formed by the edge regions of the second partial plate of the base plate and the at least one movable flap that are directed toward the floor.

Das Gerät kann auf einem selbstfahrenden Kleinlastwagen direkt aufgebaut sein oder als Anhänger zum Anhängen oder Aufliegen auf einer Zugmaschine ausgestaltet werden.The device can be built directly on a self-driving small truck or can be designed as a trailer for hanging or lying on a tractor.

Das Öffnen und Schliessen der Bitumendüsen kann über eine entsprechende Vorrichtung entweder der Fahrer oder der auf der Plattform stehende Teerwerker vornehmen.The bitumen nozzles can be opened and closed either by the driver or by the tar worker standing on the platform using a suitable device.

Um Gewicht zu sparen und dadurch eine für eine Tagesleistung ausreichende Menge Splitt mitführen zu können, besteht der Splittbehälter vorteilhafterweise aus Aluminium. Ausserdem wird das Fassungsvermögen durch eine obere seitliche Verbreiterung vergrössert. Weitere Ein- . zelheiten, Merkmale und Vorteile ergeben sich aus der nachfolgenden Beschreibung einer bevorzugten Ausführungsform der Erfindung, wie sie in der Zeichnung dargestellt ist.In order to save weight and thereby be able to carry a sufficient amount of grit for a daily output, there is a grit container advantageously made of aluminum. In addition, the capacity is increased by an upper side widening. Further input. Details, features and advantages result from the following description of a preferred embodiment of the invention, as shown in the drawing.

Das Gerät 10 kann selbstfahrbar oder als ein-oder zweiachsiger Hänger oder als Auflieger für eine Zugmaschine ausgebildet sein. Hier ist nur der funktionale Teil mit einem Rahmen 12 und Rädern 14 einer Achse dargestellt.The device 10 can be self-propelled or can be designed as a single-axle or two-axle trailer or as a trailer for a tractor. Only the functional part with a frame 12 and wheels 14 of an axle is shown here.

Die Darstellung eines Fahrerhauses eines Selbstfahrers ist ebenso weggelassen wie die einer Zugmaschine, auf die ein Hänger mit dem funktionalen Teil aufliegen kann oder die einen entsprechend gestalteten Hänger zu ziehen vermag. In jedem Fall weit das Gerät 10 in üblicher Weise an einem Rahmen 12 angeordnete Fahrzeugräder 14 auf, die angetrieben oder nachgezogen werden und die im dargestellten Beispiel die in Fahrtrichtung hintere Achse bilden. Im vorderen Teil des Gerätes 10 befindet sich ein Bindemittelkessel 16, der unter Druck steht und dessen Inhalt von einer Heizung 18 auf eine Betriebstemperatur gehalten wird. Zur Aufrechterhaltung eines Betriebsdrucks dienen Luftdruckkessel 20 und 22, welche sich über eine Ventilvorrichtung 24 füllen und entleeren lassen. Beim Aufbau des Gerätes 10 auf ein selbstfahrendes Fahrzeug kann der ohnehin vorhandene Kompressor zum Laden benutzt werden oder das Antriebsaggregat kann für diesen Zweck mit dem Kompressor versehen werden. Am Bindemittelkessel 16 sind ausserdem die erforderlichen Sicherheitseinrichtungen vorgesehen. Über eine Steuereinrichtung 26, die im Fahrerhaus oder alternativ bzw. zusätzlich auch als Steuereinheit 26A an der Fahrzeugrückwand angeordnet sein kann und die in einfachster Ausführung ein Dreiwegehahn für das Bindemittel und den Luftdruck ist, lässt sich während der Fahrt bewirken, dass das Bindemittel, in der Regel Bitumen, aus dem Kessel 16 mittels Druckluft aus dem Druckkessel 20 und 22, die Leitungen 28, 30 und 32 bzw. 32A an Düsen 34 geliefert wird.The illustration of a driver's cab of a self-propelled vehicle is omitted, as is that of a tractor on which a trailer with the functional part can rest or which can pull a suitably designed trailer. In any case, the device 10 has in the usual way on a frame 12 arranged vehicle wheels 14 which are driven or tightened and which in the example shown form the rear axle in the direction of travel. In the front part of the device 10 there is a binder tank 16 which is under pressure and the contents of which are kept at an operating temperature by a heater 18. Air pressure vessels 20 and 22 are used to maintain an operating pressure and can be filled and emptied via a valve device 24. When the device 10 is installed on a self-driving vehicle, the compressor which is already present can be used for charging, or the drive unit can be provided with the compressor for this purpose. The necessary safety devices are also provided on the binder tank 16. A control device 26, which can be arranged in the driver's cab or alternatively or additionally as a control unit 26A on the rear wall of the vehicle and which in its simplest form is a three-way valve for the binding agent and the air pressure, can be used to cause the binding agent, in usually bitumen, from the boiler 16 by means of compressed air from the pressure vessel 20 and 22, the lines 28, 30 and 32 and 32A are supplied to nozzles 34.

Dort tritt es als ein Spritzkegel 36 aus, der auf die gewünschte Stelle der Fahrbahn 40 gerichtet ist.There it emerges as a spray cone 36, which is directed at the desired location on the roadway 40.

In der Leitung 32 ist ein Umlenkhahn 38 angeordnet, mit dessen Hilfe der Bitumenstrom in einer Zuleitungsschlauch 42 einer üblichen Handlanze 44 umgelenkt werden kann. Normalerweise befindet sich diese Handlanze 44 an einer Auflage 46, die an einer Stützstrebe 48 angeordnet ist. Diese Handspritzlanze 44 ist für kleine Nebenarbeiten der ausserhalb von den Düsen 34 erreichbaren Ausbesserungsflächen vorgesehen, wofür das Fahrzeug 10 angehalten wird.A deflection valve 38 is arranged in line 32, with the aid of which the bitumen stream in a supply hose 42 of a conventional hand lance 44 can be deflected. This hand lance 44 is normally located on a support 46 which is arranged on a support strut 48. This hand-held spray lance 44 is intended for small auxiliary work on the repair surfaces which can be reached outside of the nozzles 34, for which the vehicle 10 is stopped.

Um diese Nebenarbeiten im konventionellen Sinn vornehmen zu können, ist eine Entnahmestelle 78 vorgesehen, aus welcher mit einer mitgeführten Schippe Splitt 52 von Hand entnommen werden kann.In order to be able to carry out this secondary work in the conventional sense, a removal point 78 is provided, from which chips 52 can be removed by hand with a shovel carried along.

Der Splitt befindet sich in einem oben offenen Splittbehälter 50, vorzugsweise aus Aluminium, welcher einen im einen Winkel zur horizontalen Fahrzeugachse geneigten Boden 54 aufweist. Vorteilhafterweise beträgt die Neigung = 10°. Zur besseren Ausnutzung des Fahrzeugs 10 ist der Splittbehälter 50 oben um die beidseitigen Abschnitte 56 verbreitert, welche von den Stützen 48 unterfangen sind. Im Bereich einer Rückwand 58 ist am hinteren Ende des Bodens 54 ein länglicher Splittentnahmetrichter 60 angeordnet, dessen Rückwand 66 über einen Handhebel 64 bedienbar so beweglich ist, dass ein Spalt 66 am unteren Ende des Trichters 60 für eine dosierte Splittentnahme entsteht.The grit is located in a grit container 50 open at the top, preferably made of aluminum, which has a bottom 54 inclined at an angle to the horizontal vehicle axis. The inclination is advantageously = 10 °. For better utilization of the vehicle 10, the grit container 50 is widened at the top by the sections 56 on both sides, which are underpinned by the supports 48. In the area of a rear wall 58, an elongated chip removal funnel 60 is arranged at the rear end of the bottom 54, the rear wall 66 of which can be operated via a hand lever 64 so that a gap 66 is formed at the lower end of the funnel 60 for a metered removal of chips.

Da die Arbeit während des Fahrens des Fahrzeugs stattfindet, ist am rückwärtigen Ende des Fahrzeugrahmens 12 eine Plattform 70 angeordnet, auf welcher ein Teerwerker bequem stehen und den Handhebel 64 bedienen kann. Erforderlichenfalls kann auch eine in diesem Bereich angeordnete Steuereinheit 26A mitbedient werden.Since the work takes place while the vehicle is driving, a platform 70 is arranged at the rear end of the vehicle frame 12, on which a tar worker can stand comfortably and operate the hand lever 64. If necessary, a control unit 26A arranged in this area can also be operated.

In der Plattform 70 ist eine Ausnehmung 68 im Bereich des mit dem Hebel 64 einstellbaren Spaltes 66 im Trichter 60 vorgesehen, um eine dosierte Menge 72 des Splitts hindurchtreten zu lassen. Überwiegend sind bei Ausbesserungsarbeiten Spurrillen zu beseitigen oder auszugleichen oder Randstreifen zu bearbeiten. Deshalb befindet sich nach einer Ausgestaltung der Erfindung die Anordnung von Spritzdüsen 36 kurz hinter einem oder beiden Hinterrädern, oberhalb des auszubessernden Streifens. Der Fahrer kann das Fahrzeug leicht in der auszubessernden Spur so halten, dass sich das Hinterrad in der Spur befindet. Es wurde herausgefunden, dass eine Abdeckbreite von 0,56 m sowohl für den Spritzbereich der Düsen als auch die Schüttbreite der Öffnung 66 für den Splittaustritt 72 ausreicht, um eine eingefahrene Spurrille auszufüllen und dem übrigen Belagniveau wieder anzugleichen. In der auszugleichenden Breite fällt dann Splitt 74 auf die unmittelbar zuvor mit dem Bindemittel Bitumen angespritzte Strassenfläche.A recess 68 is provided in the platform 70 in the region of the gap 66 in the hopper 60 which can be adjusted with the lever 64 in order to allow a metered amount 72 of the chips to pass through. Mainly during repair work, ruts have to be removed or compensated for or edge strips have to be worked on. Therefore, according to one embodiment of the invention, the arrangement of spray nozzles 36 is located just behind one or both rear wheels, above the strip to be repaired. The driver can easily keep the vehicle in the lane to be repaired so that the rear wheel is in the lane. It was found that a covering width of 0.56 m is sufficient for both the spray area of the nozzles and the pouring width of the opening 66 for the split outlet 72 in order to fill in a retracted track groove and to adjust it again to the remaining surface level. In the width to be compensated, grit 74 then falls on the road surface that was previously sprayed with the bitumen binder.

Nach der Ausgestaltung der Erfindung können entweder mehrere Einheiten von beispielsweise drei Spritzdüsen 34 über die gesamte Fahrzeugbreite in einer Reihe angeordnet sein, die sich über Regel- und Einstellorgane in beliebiger Streifenbreite zu- oder abschalten lassen, um sich den unterschiedlichen Ausbesserungsanforderungen anpassen zu können. In Übereinstimmung hiermit lässt sich die Rückwand 62 derart unterteilen, dass sich nur bestimmte, mit dem Handhebel 64 verriegelbare Abschnitte zur Bildung einer abschnittweisen oder über die gesamte Breite durchgehenden Öffnung 66 betätigen lassen. Eine Verriegelung 76 ist hierfür entsprechend einstellbar.According to the embodiment of the invention, either several units of, for example, three spray nozzles 34 can be arranged in a row over the entire width of the vehicle, which can be switched on or off in any strip width via regulating and adjusting elements in order to be able to adapt to the different repair requirements. In accordance with this, the rear wall 62 can be subdivided in such a way that only certain sections that can be locked with the hand lever 64 can be actuated to form a section 66 that is section-wise or that is continuous over the entire width. A lock 76 can be adjusted accordingly for this.

Es ist auch möglich, eine Gruppe von Düsen 34 über einen Schlauchabschnitt 32A mit der Zuleitung 32 flexibel zu verbinden, so dass eine oder mehrere Gruppen an gewünschten Stellen der Fahrzeugbreite relativ zum Fahrzeug angeordnet werden können und von dieser wählbaren Anbauart mit einer entsprechenden beweglichen Unterteilung der Rückwand 62 zusammenwirken. Auf diese Weise lässt sich das Gerät optimal unterschiedlichen Anforderungen anpassen. Sollten dennoch Stellen auszubessern sein, die sich nicht im fahrenden Betrieb erfassen lassen, wird angehalten und die entfernt liegende Stelle wird mit der mitgeführten Handspritzlanze 44 mit Bitumen versorgt und anschliessend in konventioneller Weise mitSplitt bestreut. Hierfür ist eine verschliessbare oder offene Entnahmestelle 78 vorgesehen.It is also possible to flexibly connect a group of nozzles 34 to the feed line 32 via a hose section 32A, so that one or more groups at the desired locations on the Vehicle width can be arranged relative to the vehicle and cooperate with a corresponding movable subdivision of the rear wall 62 of this selectable type of attachment. In this way, the device can be optimally adapted to different requirements. If, however, areas need to be repaired that cannot be detected while the vehicle is in motion, the vehicle is stopped and the remote location is supplied with bitumen with the hand spray lance 44 carried along and then sprinkled with chippings in a conventional manner. A closable or open removal point 78 is provided for this.

Ein besonders kostengünstiges und leistungsfähiges Gerät 10 lässt sich auf einer Pritsche eines Kleinkraftwagens aufbauen. Als besonders geeignet erweist sich ein Fahrzeug unter 7,5 t Gesamtgewicht und kurzem Radstand von etwa 3,60 m, um auf nicht stark belastbaren Wirtschaftswagen genügend manövrierfähig zu bleiben. Mit dem Fahrzeugmotor lässt sich ein Drucklufterzeuger verbinden oder ein vorhandener Kompressor kann dazu benutzt werden, die Druckkessel 20 und 22 zu füllen. Auch die Heizung 18 lässt sich vom Fahrzeug aus betreiben. Die Steuereinheit 26 kann im Fahrerhaus untergebracht werden. Der Bindemittelkessel 16 kann bei einem Durchmesser von 0,9 m 700 I Inhalt haben und unter einem Betriebsüberdruck von 4 atü stehen. Das Bindemittel ist normalerweise Bitumen in der Handelsbezeichnung U 60 k. Eine Füllung beträgt 0,6 t.A particularly inexpensive and powerful device 10 can be built on a platform of a small motor vehicle. A vehicle with a total weight of less than 7.5 t and a short wheelbase of around 3.60 m has proven to be particularly suitable in order to remain sufficiently manoeuvrable on commercial vehicles that are not particularly strong. A compressed air generator can be connected to the vehicle engine or an existing compressor can be used to fill the pressure vessels 20 and 22. The heater 18 can also be operated from the vehicle. The control unit 26 can be accommodated in the driver's cab. The binder vessel 16 can have a content of 700 l with a diameter of 0.9 m and be under an operating pressure of 4 atm. The binder is usually bitumen under the trade name U 60 k. One filling is 0.6 t.

Bei einer einfachen Ausführungsform überstreichen eine Gruppe von drei Düsen 34 m mit 5,5 mm Öffnungsweite, kurz hinter dem rechten Hinterrad 14 etwa 240 mm über der Strasse 40 angeordnet, eine Breite von 0,64 m. Der Splittbehälter 50 hat ein auf den Bindemitteltank 16 abgestimmtes Fassungsvermögen von 3 t Splitt, wofür eine axiale Länge von 2500 mm zur Verfügung stehen. Es wird zumeist Granitedelsplitt in einer Körnung zwischen 2 bis 5 mm verarbeitet. Bei Betätigung des Handhebels 64 lässt die Öffnung 66 einen Spalt von etwa 18 mm zu, aus dem eine optimale Splittabgabe für das aufgebrachte Bindemittel gewährleistet ist. Die hierzu angepasste Fahrzeuggeschwindigkeit lässtsich leicht empirisch ermitteln.In a simple embodiment, a group of three nozzles 34 m with a 5.5 mm opening width, arranged just behind the right rear wheel 14 about 240 mm above the road 40, cover a width of 0.64 m. The grit container 50 has a capacity of 3 t of grit matched to the binder tank 16, for which an axial length of 2500 mm is available. Mostly granite chippings are processed in a grain size between 2 and 5 mm. When the hand lever 64 is actuated, the opening 66 allows a gap of approximately 18 mm, from which an optimal release of chips for the applied binder is guaranteed. The vehicle speed adapted for this can easily be determined empirically.

Die Hauptvorteile liegen in einer angenehmen und sauberen Bedienbarkeit des Geräts sowie in der hervorragenden Leistung und den daraus resultierenden Einsparungen.The main advantages are a pleasant and clean usability of the device as well as in the excellent performance and the resulting savings.

Das soll abschliessend mit einem Beispiel belegt werden.Finally, this should be demonstrated with an example.

Bei einem konventionellen Betrieb zum Ausbessern eines Wirtschaftsweges mit ausgefahrenen Spurrillen werden ausser den auf Anhängern mitgeführten mehreren Gerätschaften neben dem Fahrer für eine Zugmaschine (der nicht in den Vergleich mit einbezogen wird) an einem Arbeitstag mit 8 Stunden Arbeitszeit benötigt:

Figure imgb0001
In a conventional operation for repairing an agricultural road with extended ruts, in addition to the several devices carried on trailers, the driver and a tractor (which is not included in the comparison) are required on a working day with 8 hours working time:
Figure imgb0001

Rechnet man die aufgewendeten Warteinheiten auf eine Tonne verarbeiteten Bitumen um, so ergeben sich 1.651 WE:0,7 = 2.3586 WE/TonneIf you convert the waiting units used to a ton of processed bitumen, you get 1,651 units: 0.7 = 2,358 units / ton

Demgegenüber lassen sich mit dem neuen Gerät gemäss der Erfindung mit nur einem Teerwerker am gleichlangen Arbeitstag mit 8 Std. Arbeitszeit 1,8 t Bitumen gemäss nachstehender Tabelle II verarbeiten:

Figure imgb0002
In contrast, with the new device according to the invention, with only one tar worker on the same working day with 8 hours of working time, 1.8 t of bitumen can be processed according to Table II below:
Figure imgb0002

Ausser der höheren Tagesleistung bei weniger Arbeitskräften ergibt sich pro Tonne verarbeiteten Bitumen folgende Kostensituation:

Figure imgb0003
Im Vergleich ergibt sich
Figure imgb0004
 In addition to the higher daily output with fewer workers, the following cost situation per ton of bitumen processed results:
Figure imgb0003
 The comparison shows
Figure imgb0004

Mithin werden mit dem neuen Gerät um 60,15% Kosten der herkömmlichen Aufwendungen benötigt oder das neue Gerät erzielt eine Kostenersparnis von etwa 40%. Bei nur 100 Einsatztagen im Jahre beträgt die Ersparnis etwa soviel, wie für die Investition des neuen Gerätes aufzuwenden ist. Damit ist ein erheblicher und nicht vorhersehbarer Fortschritt belegt.As a result, the new device requires 60.15% of the costs of conventional expenses, or the new device achieves cost savings of around 40%. With only 100 working days a year, the savings are about as much as the investment in the new device. This proves significant and unpredictable progress.

Das neue Gerät lässt sich aber ausser den hier dargestellten Beispielen auch mit Vorteil zur Oberflächenbehandlung voller Strassenbreiten auch dann einsetzen, wenn die Asphaltdecke über die vorstehend abgegebenen Masse in der Breite hinausgeht. Es ist in einfacher Abwandlung möglich, auch dann die volle Breite zur Erneuerung oder Nachbehandlung der Verschleissdecke einzusetzen.In addition to the examples shown here, the new device can also be used to advantage for surface treatment of full street widths even if the asphalt surface exceeds the width given above. In a simple modification, it is also possible to use the full width for the renewal or post-treatment of the wear blanket.
