Das Basis-Chassis 110 weist des Weiteren eine Fräseinrichtung 130 zum Entfernen und Zerkleinern von Deckschichtteilen aus der Nachbarschaft einer Schadstelle einer Fahrbahn auf, wobei im Wege der Zerkleinerung die Herstellung eines Granulats erfolgt. Der Vorratsspeicher 120 ist ausgelegt, um neben der Bitumenemulsion auch ein Sand/Kies-Gemisch zu enthalten.The base chassis 110 is provided with a storage 120 for storing bitumen in the form of an emulsion and created granules and additional granules. The base chassis 110 further comprises a milling device 130 for removing and crushing of cover layer portions from the vicinity of a damaged area of a roadway, wherein by the crushing the production of a Granules are made. The storage 120 is designed to contain in addition to the bitumen emulsion and a sand / gravel mixture.

Des Weiteren enthält das Basis-Chassis 110 eine Fördereinrichtung zum Fördern des Granulats in eine Mischzone 140, in der ein Vermischen des Granulats mit wenigstens der Bitumenemulsion zum Bilden einer aushärtbaren Masse erfolgt.Furthermore, the base chassis 110 includes a conveyor for conveying the granules into a mixing zone 140 in which the granules are mixed with at least the bitumen emulsion to form a hardenable mass.

Die aushärtbare Masse ist dann mittels einer steuerbaren Auslassöffnung 150 dosiert in eine mittels der Fräseinrichtung 130 geschaffene Aussparung in der Deckschicht der Fahrbahn einbringbar.The hardenable mass is then metered by means of a controllable outlet opening 150 into a created by means of the milling device 130 recess in the top layer of the roadway introduced.

Die Fräseinrichtung 130 ist von einer rotierbaren zylindrischen Trommel gebildet, deren Oberfläche mit einer Mehrzahl von Asphalt abtragenden Fräselementen 131 versehen ist. Die Trommel ist dabei in Fahrtrichtung vor dem Basis-Chassis 110 angeordnet, und die Achse der Trommel ist senkrecht zur Fahrtrichtung orientiert, um bei Rotation der Trommel eine hohlquaderförmige Aussparung in der Deckschicht auszubilden.The milling device 130 is formed by a rotatable cylindrical drum whose surface is provided with a plurality of asphalt-removing milling elements 131.

Die Zerkleinerungseinrichtung 160 enthält zwei in vorgegebenem Abstand parallel angeordnete und dabei einen Zwischenraum bildende rotierbare Trommeln, die in Fahrtrichtung hinter der Fräseinrichtung 130 angeordnet sind und deren Achsen senkrecht zur Fahrtrichtung orientiert sind, wobei der Zwischenraum zwischen den Trommeln als Zerkleinerungszone für Asphalt-Granulat vorgesehen ist.The comminution device 160 contains two rotatable drums arranged in parallel at a predetermined spacing and forming a gap, which are arranged behind the milling device 130 in the direction of travel and whose axes are oriented perpendicular to the direction of travel, the space between the drums being provided as a comminuting zone for asphalt granules ,

Im in Fahrtrichtung hinteren Bereich des Basis-Chassis 110 ist ein Anpresselement ausgebildet, mittels dessen ein vorgebbarer Druck auf eine in eine Aussparung einer Fahrbahn-Deckschicht eingebrachte aushärtbare Masse aufbringbar ist, um für ein Aushärten Wasser aus der Bitumen-Emulsion der aushärtbaren Masse auszutragen.In the rear direction of the base chassis 110 in the direction of travel, a pressing element is formed, by means of which a specifiable pressure can be applied to a curable mass introduced into a recess of a road surface layer in order to discharge water from the bitumen emulsion of the hardenable mass for hardening.

Das Anpresselement 170 ist von einer Bohle gebildet, die ausgelegt ist, um eine Anpressdruck im Bereich von 1 bar bis 100 bar auf die aushärtbare Masse auszuüben.The pressing element 170 is formed by a screed, which is designed to exert a contact pressure in the range of 1 bar to 100 bar on the curable composition.

Das oben erläuterte Ausführungsbeispiel der Erfindung dient lediglich dem Zweck eines besseren Verständnisses der durch die Ansprüche vorgegebenen erfindungsgemäßen Lehre, die als solche durch das Ausführungsbeispiel nicht eingeschränkt ist.The above-described embodiment of the invention is only for the purpose of better understanding of the teaching of the invention predetermined by the teaching, which is not limited as such by the embodiment.
