Die Erfindung bezieht sich auf ein Verfahren zur Herstellung einer Abdichtung von Fahrbahnen z.B. auf Brücken sowie zur Aufbringung eines erneuerbaren Verschleißbelages, wobei die vorbehandelte Betonfahrbahn mittels eines Harzes versiegelt und mit Quarzsand abgestreut wird, worauf eine Folie auf Polyurethan-Basis heiß aufgespritzt wird. 5The invention relates to a method for producing a seal of roadways, e.g. on bridges and for the application of a renewable wear lining, wherein the pre-treated concrete pavement is sealed by means of a resin and sprinkled with quartz sand, whereupon a film based on polyurethane is hot-sprayed. 5
Es ist bekannt, daß als Verbindungselement zwischen Brückenabdichtung und dem Verschleißschutz auf Basis Asphaltbeton in der Regel eine bis zu 3 cm starke Gußasphaltschicht eingebracht wird. Gerade dieser Thermoplast ist es, der verstärkt durch die immer höheren Achslasten unter Temperatureinfluß zur Verformung durch Auswalkung und dadurch in letzter Konse-io quenz zu einer dauerhaften Schädigung des Verschleißbelages führt. Das Resultat ist eine Verkürzung der Standzeit des Fahrbahnbelages, die wiederum kapital- und zeitaufwendige Sanierungen nach sich zieht.It is known that as a connecting element between bridge waterproofing and wear protection based on asphalt concrete usually up to 3 cm thick Gußasphaltschicht is introduced. Especially this thermoplastic is reinforced by the ever higher axle loads under the influence of temperature to deformation by leaching and thus in last Konse-io quenz leads to permanent damage to the wear lining. The result is a reduction in the service life of the road surface, which in turn entails capital and time-consuming renovations.
Die Erfindung hat es sich zum Ziel gesetzt, ein neues Verfahren zu schaffen, das eine Guß-15 asphaltschicht vermeidet, um somit nicht nur eine Verlängerung der Lebensdauer des Fahrbahnbelages durch Wegfall der Verformungsschicht zu erreichen, sondern darüber hinaus durch die Möglichkeit des Abfräsens des Altbelages und den Auftrag einer neuen Verschleißschicht eine schnelle und preiswerte Sanierungsmöglichkeit anzubieten. Es soll dadurch eine Abdichtung geschaffen werden, die hinsichtlich Belastbarkeit, Lebensdauer und Verarbeitbar-20 keit den heutigen hohen Belastungen und den extremen klimatischen Bedingungen entspricht.The invention has set itself the goal of creating a new process that avoids a cast asphalt layer, so as not only to achieve an extension of the life of the pavement by eliminating the deformation layer, but also by the possibility of milling off the old pavement and to offer the order of a new wear layer a fast and inexpensive rehabilitation option. It is intended to create a seal that meets today's high loads and the extreme climatic conditions with regard to load capacity, service life and processability.
Erreicht wird dies, ausgehend von einem Verfahren der eingangs genannten Art dadurch, daß anschließend ein Klebeprimer auf Polyurethan-Basis aufgebracht und dieser mit einem Granulat auf Basis eines synthetischen Harzes vollflächig abgestreut wird, worauf eine bituminöse 25 Tragschicht aufgebracht wird.This is achieved, starting from a method of the type mentioned in that then applied an adhesive primer polyurethane-based and this is sprinkled over the entire surface with a granulate based on a synthetic resin, whereupon a bituminous support layer is applied.
Dieses synthetische Harz zeichnet sich durch die für das Funktionieren des Systems wesentliche Eigenschaft aus, daß es beim Einbringen des Heißmischgutes mit diesem verschmilzt und somit zu einem praktisch monolithischen Körper wird. Dieser Körper besitzt sowohl hinsichtlich 30 eines Schubverbundes wie auch der Haftzugfestigkeit jene Eigenschaften, durch die die Nachteile der durch die bekannten Verfahren hergestellten Abdichtungen von Fahrbahnen, insbesondere auf Brücken, nicht auftreten. Ein partielles Abfräsen der Verschleißschicht wird möglich, ohne daß Strukturstörungen auftreten. Erst dadurch wird ein relativ problemloser und kostengünstiger Neuaufbau des Fahrbahnbelages ermöglicht. 35This synthetic resin is characterized by the essential for the functioning of the system property that it merges with the introduction of the hot mix with this and thus becomes a virtually monolithic body. This body has both in terms of a shear bond as well as the adhesive tensile strength those properties by which the disadvantages of the seals produced by the known methods of roadways, especially on bridges, do not occur. Partial milling of the wear layer becomes possible without structural disturbances. Only then is a relatively trouble-free and cost-effective rebuilding of the road surface possible. 35
Ein ganz wesentlicher Effekt des erfindungsgemäßen Verfahrens ist der Wegfall der Verformung des bisher zum Einsatz kommenden Gußasphaltes mit den eingangs aufgezählten Schäden. Aufgrund der hohen Haftzugwerte in Kombination mit dem ebenfalls hohen Schubverbund besteht auch die Möglichkeit des Einsatzes einer durch das erfindungsgemäße Verfahren her-40 gestellten Abdichtung und Belages von Fahrbahnen in Gefälle- oder Bremsstrecken.A very significant effect of the method according to the invention is the elimination of the deformation of the previously used Gußasphaltes with the initially enumerated damage. Due to the high adhesive pull values in combination with the likewise high shear connection, there is also the possibility of using a sealing and lining of roadways in gradients or braking distances provided by the method according to the invention.
Vorteile eines durch das erfindungsgemäße Verfahren hergestellten Belages sind insbesondere zur Vermeidung von Verkehrsbehinderungen immer kürzere Bauzeiten, 45 - lange Einsatzdauer, keine Zwischeninstandsetzungen, schubfeste und dauerhafte Verbindung mit hochstandfesten Belägen, dichte und verschleißfeste Verbindung mit den Einbauteilen (Entwässerungen, Fahrbahnübergangskonstruktion, Dübel u.dgl.),Advantages of a covering produced by the method according to the invention are in particular to avoid traffic obstructions ever shorter construction times, 45 - long service life, no interim repairs, shear-resistant and durable connection with high-strength coverings, dense and wear-resistant connection with the mounting parts (drainage, roadway construction, dowels and the like .)

Als Klebeprimer auf Polyurethan-Basis hat sich bei durchgeführten Versuchen ein modifiziertes Polyether Polyol in Verbindung mit einem formulierten Isozyanat bewährt.As a polyurethane-based adhesive primer, a modified polyether polyol in conjunction with a formulated isocyanate has proven successful in experiments.
Das Granulat auf Basis eines synthetischen Harzes war bei einem dieser Versuche ein modifi-55 ziertes thermoplastisches Polyolefin.The granules based on a synthetic resin in one of these experiments was a modified thermoplastic polyolefin.
