Abstract
Die Verbesserung der Griffigkeit polierter Fahrbahnoberflächen erfolgt nach dem derzeitigen Stand der Technik durch Überbauen der vorhandenen Deckschicht oder durch Materialabtrag. Der Abtrag von Material geschieht durch Anfräsen, Abschleifen, Rilleneinschneiden, Anreißen, Abhämmern, Sandstrahlen oder Flammstrahlen. Mit Ausnahme des Sandstrahlens sind alle diese Verfahren mit relativ großem Substanzverlust für die Deckschicht und mit entsprechend hohem Aufwand verbunden. Wie sich durch überraschende Beobachtungen und durch nachfolgende Untersuchungen herausgestellt hat, läßt sich die Griffigkeit jedoch schon durch die mechanische Einwirkung einer Glattradwalze langfristig verbessern, wenn ihr Flächendruck durch Verringerung der Aufstandsfläche entsprechend gesteigert wird. Dabei entstehen in den hervortretenden Deckenbestandteilen Strukturstörungen, die für eine wesentliche Verbesserung der Griffigkeit ausreichen, ohne daß ein nennenswerter Substanzverlust eintritt. Augenscheinlich bleibt die so behandelte Teilfläche nahezu unverändert. Die für die Griffigkeit bei (meist ausreichender Rauhtiefe) ausschlaggebende Mikrostruktur ist jedoch entscheidend verändert. Glattradwalzen sind für gezielte Verbesserungen der Griffigkeit nicht geeignet, weil die gebräuchlichen Bandagen die Oberflächen alter Straßen nur in Teilflächen berühren und bei vollflächigem Kontakt keine ausreichenden Pressungen erbringen. Das erfindungsgemäße Verfahren nutzt die vorerwähnte überraschende ...........The grip of polished road surfaces is improved according to the current state of the art by building over the existing surface layer or by removing material. Material is removed by milling, grinding, grooving, scribing, hammering, sandblasting or flame blasting. With the exception of sandblasting, all of these processes involve a relatively large loss of substance for the top layer and a correspondingly high level of effort. As has been shown by surprising observations and by subsequent investigations, the grip can, however, be improved in the long term by the mechanical action of a smooth-wheel roller if its surface pressure is increased accordingly by reducing the contact area. Structural disturbances arise in the protruding ceiling components, which are sufficient for a substantial improvement in grip without a significant loss of substance occurring. Apparently, the partial area treated in this way remains almost unchanged. However, the microstructure, which is decisive for the grip with (usually sufficient surface roughness), has changed significantly. Smooth rollers are not suitable for targeted improvements in grip, because the conventional bandages only touch the surfaces of old roads in partial areas and do not provide sufficient pressure when they are in full contact. The inventive method uses the aforementioned surprising ...........
Description
Die Erfindung betrifft eine fahrbare Vorrichtung zum Aufrauhen von glatten Fahrbahnen aus Beton oder mit bituminösen Deckschichten.The invention relates to a mobile device for roughening smooth roads made of concrete or with bituminous surface courses.
Bekannte Vorrichtungen dieser Art zielen darauf ab, die aite (glatte) Oberfläche ganz oder teilweise abzutragen und tieferliegende Teile der Deckschicht als neue Fahrbahnoberfläche freizulegen. Dies geschieht durch Anfräsen, Abschleifen, Rilleneinschneiden, Anreißen, Abhämmern, Sandstrahlen oder Flammstrahlen. Nachteilig bei diesen bekannten Vorrichtungen ist jedoch, daß sie im Einsatz kostenaufwendig sind und einen verhältnismäßig großen Materialverlust an der betroffenen Deckschicht bewirken.Known devices of this type aim to remove all or part of the aite (smooth) surface and to expose deeper parts of the surface layer as a new road surface. This is done through Milling, grinding, grooving, scribing, hammering, sandblasting or flame blasting. Disadvantageous in these known devices, however, is that they are expensive to use and a relative one cause a large loss of material on the affected surface layer.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Aufrauhen von glatten Fahrbahnen aus Beton oder mit bituminösen Deckschichten zu schaffen, die im Einsatz bei geringem Kostenaufwand nur einen geringfügigen Materialverlust an der zu bearbeitenden Fahrbahn-Deckschicht verursacht.The invention is based on the object of providing a device for roughening smooth roads Concrete or bituminous cover layers that can be used at low cost only one causes a slight loss of material on the pavement surface layer to be processed.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Vorrichtung relativ schmale, am Fahrzeugrahmen aufgehängte Walzenkörper od. dgl. aufweist, die in Gruppen neben- und/oder hintereinander angeordnet sind, harte Mantelflächen haben und mit einer so hohen Auflast beaufschlagt sind, daß sie beim Rollen über die zu bearbeitende Fahrbahnoberfläche die obere Zone der Fahrbahn-Mineralstoffc durch Anbrechen aufrauhen. According to the invention, this object is achieved in that the device is relatively narrow on the vehicle frame Has suspended roller bodies or the like, which are arranged in groups next to one another and / or one behind the other are, have hard surfaces and are subjected to such a high load that they roll over the Road surface to be processed roughen the upper zone of the road mineral material by cracking it.
Die Walzenkörper od. dgl. mit ihren harten Mantelflächen bewirken infolge der hohen Auflast allein durch Abrollen auf der Fahrbahnoberfläche griffigkeitsverbessernde Gefügestörungen, vorwiegend an den hervorstehenden Mineralstoffkörnern, ohne daß es dabei /u einem nennenswerten Substanzverlust der Deckschicht durch Materialabtrag kommt. Durch die Einzelaufhängung der in Gruppen neben- und/oder hintereinander angeordneten, relativ schmalen Walzenkörper od. dgl. ist auch bei unebener Straßenoberfläche eine weitgehend gleichmäßige Bearbeitung derselben ge-The roller bodies or the like, with their hard outer surfaces, act on their own due to the high load Rolling off on the road surface, structural defects that improve grip, mainly on the protruding ones Mineral grains without any significant loss of substance in the top layer comes from material removal. Due to the individual suspension of the in groups next to and / or behind one another arranged, relatively narrow roller body od. The like. Is also on uneven road surfaces largely uniform processing of the same
