Description

Gegenstand der Erfindung ist ein anschmelzbares Bitumen-Fugenband für den Straßen-, Tief-, Hoch- und Kanalbau, ein Verfahren zu seiner Herstellung sowie ein Verfahren zur Verlegung des Fugenbandes an einer Naht-/Anschlußflanke einer Asphaltschicht im Straßenbau.The invention relates to a fusible bitumen joint tape for road, civil, structural and sewer construction, a method for its production and a method for laying the joint tape on a seam / connecting edge of an asphalt layer in road construction.

Schmelzbare Bitumen-Fugenbänder für den Straßen-, Tief-, Hoch- und Kanalbau werden fabrikmäßig hergestellt und stellen maschinell vorgeformte thermoplastische Bandprofile unterschiedlicher Querschnitte dar, die im wesentlichen aus Bitumen oder Bitumenmodifikationen als Bindemittel bestehen. Diese können beispielsweise Zusätze von Kunststoffen, Elastomeren, Weichmachern und mineralischen Füllstoffen enthalten.Meltable bitumen joint tapes for road, underground, civil engineering and canal construction are factory-made and are machine-preformed thermoplastic tape profiles of different cross-sections, which consist essentially of bitumen or bitumen modifications as a binder. These may contain, for example, additives of plastics, elastomers, plasticizers and mineral fillers.

In DE-U 77 28 361 wird ein Verlegegerät für selbstklebende oder anschmelzbare Dichtungsbänder beschrieben, wobei keine näheren Ausführungen zum Aufbau der Fugenbänder erkennbar sind.In DE-U 77 28 361 a laying device for self-adhesive or fusible sealing strips is described, with no further details on the construction of the joint tapes are recognizable.

DE-U 93 13 030 betrifft ein geformtes, trägerloses, bitumenhaltiges Dichtungsmaterial, beispielsweise aus einer Vormischung aus etwa 15 % fein zerrissenem Bunakautschuk und etwa 85 % Mischbitumen, die mit weiterem Mischbitumen, Öl, Schiefermehl und modifiziertem Zellufosepulver vermischt wird. Das so geformte Band wird insbesondere kalt und ohne Primer in die Nahtflanke eingelegt. DE-U 93 13 030 relates to a molded, unsupported, bituminous sealing material, for example, a premix of about 15% finely shredded bamboo rubber and about 85% mixed bitumen blended with further mixed bitumen, oil, shale meal, and modified cellulosic powder. The thus formed band is inserted in particular cold and without primer in the seam flank.

DE 196 03 896 A1 beschreibt ein kalt verarbeitbares Fugenband und ein Verfahren zur Verlegung eines Fugenbandes. Insbesondere wird ein Fugenband zur Verwendung im Straßenbau beschrieben, das aus einem Polymer-vergüteten Straßenbaubitumen besteht, das auf wenigstens einer Seite mit einer Kleberschicht versehen ist. Mit diesem Fugenband soll die Aufgabe gelöst werden, ein Fugenband und ein Verfahren zu schaffen, das eine kalte Verlegung, d.h. ohne Zuhilfenahme einer Flamme, ermöglicht. DE 196 03 896 A1 describes a cold processable joint tape and a method for laying a joint tape. In particular, a joint tape for use in road construction is described, which consists of a polymer-coated road bitumen, which is provided on at least one side with an adhesive layer. This joint tape is to be achieved the task of creating a joint tape and a method that allows a cold installation, ie without the aid of a flame.

Das Aufbringen einer dort beschriebenen Kleberschicht auf das Fugenband hat jedoch den Nachteil, daß zum einen die Lagerbeständigkeit des Fugenbandes durch die relative Unbeständigkeit des Klebers, im Gegensatz zum Bitumen, in der Regel negativ beeinträchtigt werden kann. Darüber hinaus beeinträchtigt eine Kleberschicht insbesondere auf der Basis von SBS/SIS-Blockcopolymeren die Haftung der Fugenbänder an den Fugenflanken, insbesondere wenn das Fugenband oder die Naht-/Anschlußflanke mit einer Propangasflamme angewärmt wird oder auch durch die Temperatur des Mischguts der neu einzubringenden Asphaltoder Deckschicht, die unmittelbar an das verlegte Fugenband herangebracht wird, sehr hoch ist.However, the application of an adhesive layer described there on the joint tape has the disadvantage that on the one hand, the storage stability of the joint strip by the relative instability of the adhesive, in contrast to the bitumen, can generally be adversely affected. In addition, an adhesive layer, in particular based on SBS / SIS block copolymers, impairs the adhesion of the joint tapes to the joint flanks, in particular if the joint tape or the seam / terminal flank is warmed with a propane gas flame or else by the temperature of the mixed material of the asphalt or cover layer to be newly introduced , which is brought directly to the installed joint tape is very high.

Das Probem der vorliegenden Erfindung besteht darin, ein gegenüber dem Stand der Technik verbessertes Bitumen-Fugenband für den Straßen-, Tief-, Hoch- und Kanalbau zur Verfügung zu stellen. Dieses Problem wird erfindungsgemäß in einer ersten Ausführungsform mit einem anschmelzbaren Bitumen-Fugenband gemäß Anspruch 1 gelöst.The problem of the present invention is to provide a bitumen joint tape for road construction, civil engineering, building construction and sewerage that is improved over the prior art. This problem is solved according to the invention in a first embodiment with a fusible bitumen joint tape according to claim 1.

Während überwiegend im Stand der Technik vor Anbringen des Fugenbandes im allgemeinen ein Bitumen-haltiges Voranstrichmittel oder ein Primer auf die Naht-/Anschlußflanke gesprüht oder gestrichen wurde, um die Haftung des Fugenbandes beim Anbringen zu unterstützen und auch gegebenenfalls Staub zu binden, ist es mit Hilfe der vorliegenden Erfindung bei entsprechenden günstigen Außentemperaturen und sauberen Kanten/Flanken in der Regel möglich, auf den Voranstrich zu verzichten. Die Anwendung eines Primers ist bei allen Temperaturen verzichtbar. Das erfindungsgemäße Fugenband verbleibt nach dem Andrücken mit einem Holz-/Metallspatel oder einem anderen geeigneten Werkzeug selbstständig an der Kante/Flanke. Die Erfindung geht davon aus, daß es in der Praxis - vomehmlich bei ungünstiger Witterung - bekannt ist, unter Zuhilfenahme eines Gasbrenners, das Fugenband bereits einseitig an die Naht-/Anschlußflanke anzuschmelzen, um Verlegeprobleme zu vermeiden. Im Stand der Technik sind entsprechende Außentemperaturen bekannt. Die Anschlußflanken werden üblicherweise abgekantet, geschnitten oder vorgeschaalt und können aus vorgefertigten Baustoffen bestehen. Sie müssen möglichst glatt gemacht, fest und frei von Verunreinigungen sein, beispielsweise Rostpartikel müssen von Stahlteilen entfernt werden.While predominantly in the prior art prior to attachment of the joint tape generally a bitumen-containing primer or a primer was sprayed or painted on the seam / terminal flank to assist adhesion of the joint tape during installation and also optionally to bind dust, it is with Help the present invention with appropriate low ambient temperatures and clean edges / flanks usually possible to dispense with the primer. The application of a primer is dispensable at all temperatures. The joint tape according to the invention remains after pressing with a wood / metal spatula or other suitable tool independently at the edge / flank. The invention assumes that it is known in practice - especially in unfavorable weather conditions, with the aid of a gas burner, the joint tape already on one side to the seam / terminal edge to melt to avoid installation problems. In the prior art, corresponding outdoor temperatures are known. The connecting flanks are usually folded, cut or pre-formed and can consist of prefabricated building materials. They must be made as smooth as possible, firm and free of impurities, for example, rust particles must be removed from steel parts.

Das Verarbeiten der Fugenbänder sollte nur bei trockener Witterung und einer Oberflächentemperatur des Bauteils von +5 °C ausgeführt werden. Bei Temperaturen bis +/- 0 °C können die Arbeiten fortgesetzt werden, wenn Zusatzmaßnahmen, wie beispielsweise das Vorwärmen der Naht und/oder der Flanke, festgelegt worden sind.The processing of the joint tapes should only be carried out in dry weather and a surface temperature of the component of +5 ° C. At temperatures up to +/- 0 ° C, work may continue if additional measures have been taken, such as preheating the seam and / or flank.

Die Erfindung ermöglicht die Bereitstellung eines Fugenbandes, das mit einer Montagehilfe/Nerlegehilfe bereits fabrikmäßig ausgerüstet ist und zu jeder Jahreszeit auch ohne Hilfsmittel, wie Voranstrich/Primer oder Gasflamme, an die Naht/-Anschlußflanke angedrückt werden kann und so lange verbleibt, bis das frische Mischgut gegengebaut ist.The invention enables the provision of a joint tape that is already factory-equipped with an assembly aid / Nerlegehilfe and can be pressed at any time without aids, such as primer / gas or flame, to the seam / terminal edge and remains as long as the fresh Mischgut gegengebaut is.

Die Schmelzbeschichtung besteht praktischerweise aus einer einseitigen Beschichtung des Fugenbandes, die zur Vermeidung von Unverträglichkeiten, vornehmlich bei Asphalt oder auch Beton hauptsächlich aus Bitumen besteht. In einer besonders bevorzugten Ausführungsform der vorliegenden Erfindung besteht die Schmelzbeschichtung aus Polymer-vergüteten Bitumen. Derartige Materialien sind dem Fachmann aus dem Stand der Technik hinreichend bekannt.The melt coating is conveniently a one-sided coating of the joint tape, which consists mainly of bitumen to avoid incompatibilities, especially in asphalt or concrete. In a particularly preferred embodiment of the present invention, the melt coating consists of polymer-coated bitumen. Such materials are well known to those skilled in the art.

Die Dicke der Schmelzbeschichtung ist nicht von kritischer Bedeutung. Die Schicht sollte jedoch so dünn wie möglich aufgebracht sein. Besonders bevorzugt im Sinne der vorliegenden Erfindung ist es, das Fugenband mit einer Schmelzbeschichtung auszurüsten, die eine Dicke von 0,1 bis 2 mm, insbesondere 0,2 bis 1 mm umfaßt.The thickness of the melt coating is not critical. However, the layer should be applied as thinly as possible. Particularly preferred according to the present invention is to equip the joint tape with a melt coating which has a thickness of 0.1 to 2 mm, in particular 0.2 to 1 mm.

Erfindungsgemäß unterscheidet sich das Material des eigentlichen Bitumen-Fugenbandes von der Bitumen-haltigen Schmelzbeschichtung. Insbesondere ist es bevorzugt, daß die Bitumen-haltige Schmelzbeschichtung, beispielsweise aus Polymer-vergütetem Bitumen, eine höhere Elastizität, insbesondere ein verbessertes Kaltbiegevermögen, eine erhöhte Konuspenetration sowie ein erhöhtes Rückstellvermögen gegenüber dem eigentlichen Bitumen-Fugenband aufweist.The invention differs Material of the actual bitumen joint tape from the bitumen-containing melt coating. In particular, it is preferred that the bitumen-containing melt coating, for example made of polymer-coated bitumen, has a higher elasticity, in particular an improved cold bending capacity, an increased cone penetration and an increased resilience compared to the actual bitumen joint tape.

Besonders bevorzugt im Sinne der vorliegenden Erfindung ist es, wenn die Schmelzbeschichtung ein Kaltbiegevermögen nach DIN 52123 von -20 °C aufweist, während das Kaltbiegevermögen des Fugenbandes +/- 0 °C betragen sollte. Dies erlaubt ein Arbeiten und ein Verlegen des Fugenbandes bei Temperaturen bis zu etwa 0 °C.It is particularly preferred for the purposes of the present invention if the melt coating has a cold bending capacity according to DIN 52123 of -20 ° C, while the cold bending capacity of the joint tape should be +/- 0 ° C. This allows working and laying the joint tape at temperatures up to about 0 ° C.

In gleicher Weise ist es besonders bevorzugt, wenn die Konuspenetration nach BS 2499 der Schmelzbeschichtung wenigstens 60 bis 140 1/10 mm und die Konuspenetration des Fugenbandes 20 bis 50 1/10 mm mit der Maßgabe beträgt, daß die Differenz der Werte der Konuspenetration wenigstens 20 bis 60 1/10 mm beträgt. Hierdurch wird gewährleistet, daß sich die Schmelzbeschichtung an vorhandenen Unebenheiten an der Naht- und/oder Anschlußflanke besser anschmiegt.In the same way, it is particularly preferred if the cone penetration to BS 2499 of the melt coating is at least 60 to 140 1/10 mm and the cone penetration of the joint tape 20 to 50 1/10 mm, with the proviso that the difference in the values of the cone penetration at least 20 to 60 1/10 mm. This ensures that the melt coating better conforms to existing bumps on the seam and / or connecting flank.

Ebenfalls zum verbesserten Ausgleich gegenüber Unregelmäßigkeiten an der Nahtund Anschlußflanke ist es im Sinne der vorliegenden Erfindung besonders bevorzugt, wenn das Rückstellvermögen der Schmelzbeschichtung nach BS 2499 wenigstens 60 % bis 90 % und das Rückstellvermögen des Fugenbandes 15 % bis 55 % beträgt.Also, for improved compensation for irregularities at the seam and connecting flank, it is particularly preferred for the purposes of the present invention, if the resilience of the melt coating according to BS 2499 is at least 60% to 90% and the resilience of the joint tape 15% to 55%.

Die unterschiedlichen physikalischen Eigenschaften des Bitumen-Fugenbandes und der Bitumen-haltigen Schmelzbeschichtung können beispielsweise auch durch die Wahl unterschiedlicher Bitumen eingestellt werden. So ist es im Sinne der vorliegenden Erfindung besonders bevorzugt, das Bitumen-Fugenband aus einem Polymer-vergüteten Bitumen mit einem relativ hohen Anteil an Füllstoffen und ggf. Faserbestandteilen bereitzustellen. Demgegenüber ist es im Sinne der vorliegenden Erfindung bevorzugt, wenn bei gleichen Ausgangsbitumen fürdas Bitumenfugenband und die Bitumen-haltige Schmelzbeschichtung der Mineralstoffgehalt niedriger, und insbesondere der Polymeranteil in der Bitumen-haltigen Schmelzbeschichtung höher ist, als im Bitumen-Fugenband. Besonders bevorzugt im Sinne der vorliegenden Erfindung ist ein Fugenband, bei dem die Bitumen-haltige Schmelzbeschichtung aus 60 Gew.-% bis 93 Gew.-% Bitumen besteht. Analog dazu kann das Fugenband aus 60 Gew % bis 93 Gew % Bitumen enthalten.The different physical properties of the bitumen joint tape and the bitumen-containing melt coating can also be adjusted, for example, by the choice of different bitumen. Thus, in the context of the present invention, it is particularly preferred to provide the bitumen joint tape made of a polymer-coated bitumen with a relatively high proportion of fillers and possibly fiber constituents. In contrast, for the purposes of the present invention, it is preferred that, for the same starting bitumen for the bitumen joint tape and the bitumen-containing melt coating, the mineral content is lower, and in particular the polymer content in the bitumen-containing melt coating is higher than in the bitumen joint tape. Particularly preferred in the context of the present invention is a joint tape in which the bitumen-containing melt coating consists of 60 wt .-% to 93 wt .-% bitumen. Similarly, the joint tape may contain from 60 wt% to 93 wt% bitumen.

Die Bitumen-haltige Schmelzbeschichtung kann auf verschiedene Art und Weise auf das Fugenband aufgebracht werden. Da ohnehin ein bereits im Stand der Technik eingesetztes Trennpapier vorgesehen ist, das die Bitumen-haltige Schmelzbeschichtung abdeckt, kann es zweckmäßig sein, das erfindungsgemäße Fugenband dadurch herzustellen, daß man zunächst eine Schmelzbeschichtung auf ein Trennpapier aufträgt und dann das Fugenband auf die Rückseite der Schmelzbeschichtung aufträgt.The bitumen-containing melt coating can be applied to the joint tape in various ways. Since already provided in the prior art release paper is provided which covers the bitumen-containing melt coating, it may be appropriate to make the joint tape of the invention by first applying a melt coating on a release paper and then the joint tape on the back of the melt coating applying.

Alternativ zu dieser Ausführungsform des Herstellungsverfahrens ist es möglich, zunächst die Bitumen-haltige Schmelzbeschichtung auf das Fugenband aufzubringen und anschließend das Trennpapier aufzubringen.As an alternative to this embodiment of the production method, it is possible first to apply the bitumen-containing melt coating to the joint tape and then to apply the release paper.

Da mit Hilfe der vorliegenden Erfindung während der Verarbeitung eine Verklebung des Bitumen-Fugenbandes mit der Naht-/Anschlußflanke nicht erwünscht ist, sondern lediglich ein Halten des Fugenbandes an dem gewünschten Ort erreicht werden soll, ist es im Sinne der vorliegenden Erfindung besonders bevorzugt, die Schmelzbeschichtung nicht als durchgehende Fläche auf die Oberfläche des Fugenbandes aufzubringen, sondern diese in Form einer punktuellen, ggf. rasterförmigen Schmelzbeschichtung vorzusehen. Hierdurch wird insbesondere Material für die Schmelzbeschichtung eingespart und erfindungsgemäß der gleiche Halteeffekt erreicht, der auch mit einer durchgehenden großflächigen Schmelzbeschichtung erzielt wird. In vorteilhafter Weise ist jedoch eine Ortsveränderung des Fugenbandes möglich, bevor das Mischgut eingebracht wird, die nicht zu einer Beschädigung des Fugenbandes führt. Darüber hinaus ist ein großflächiger Kontakt des Materials des Fugenbandes mit dem Mischgut gegeben, der nur punktuell, gegebenenfalls rasterförmig durch geringe Oberflächenanteile der Schmelzbeschichtung unterbrochen ist.Since, with the aid of the present invention, adhesion of the bitumen joint tape to the seam / terminal flank is not desired during processing, but merely to maintain the joint tape in the desired location, it is particularly preferred for the purposes of the present invention Apply melt coating not as a continuous surface on the surface of the joint tape, but to provide them in the form of a punctiform, possibly grid-shaped melt coating. As a result, in particular material for the melt coating is saved and according to the invention achieves the same holding effect, which is achieved with a continuous large-scale melt coating. Advantageously, however, a change in location of the joint tape is possible before the mix is introduced, which does not lead to damage of the joint tape. In addition, a large-area contact of the material of the joint tape with the mix is given, which is interrupted only selectively, optionally grid-shaped by small surface portions of the melt coating.

Eine weitere Ausführungsform der vorliegenden Erfindung betrifft ein Verfahren zum Verlegen eines erfindungsgemäßen Fugenbandes, insbesondere an einer Naht-/Anschlußflanke einer Deckschicht im Straßenbau. Erfindungsgemäß wird das Fugenband durch Andrücken zum Halten gebracht. Dabei ist selbstverständlich zu gewährleisten, daß die Schmelzbeschichtung in Kontakt mit der Naht-/Anschlußflanke kommt.A further embodiment of the present invention relates to a method for laying a joint tape according to the invention, in particular on a seam / connecting flank of a cover layer in road construction. According to the joint tape is brought to a halt by pressing. It is of course to ensure that the melt coating comes into contact with the seam / terminal flank.

Für den Fall, daß die Witterungsbedingungen ein direktes Halten des Fugenbandes nicht erlauben, ist es auch im Sinne der vorliegenden Erfindung bevorzugt, die Naht-/Anschlußflanke und/oder das Fugenband mit einer Gasflamme anzuwärmen.In the event that the weather conditions do not allow a direct hold of the joint tape, it is also preferred in the context of the present invention, to heat the seam / terminal edge and / or the joint tape with a gas flame.

In einer alternativen Ausführungsform ist es gleichfalls möglich, die Naht-/Anschlußflanke zunächst mit einem streichfähigen, spritzfähigen, zumindest spachtelfähigen Voranstrich zu versehen, bevor das Fugenband durch Andrücken zur Fixierung gebracht wird. Als Voranstrich kommen hierbei an sich bekannte Voranstrichmittel in Frage, wie sie beispielsweise unter der Bezeichnung ColzumixⓅ im Handel erhältlich sind.In an alternative embodiment, it is also possible to provide the seam / terminal flank initially with a spreadable, sprayable, at least spatulatable primer before the joint tape is brought to fixation by pressing. As a primer in this case known pre-paint in question, as they are available, for example, under the name Colzumix® commercially.

Die Nähte und/oder Flanken müssen sauber und trocken sein. Anhaftende Schmutzreste sind insbesondere mit einer Drahtbürste oder Druckluft zu entfernen. Feuchte Flanken können mit Heißluft getrocknet werden.The seams and / or flanks must be clean and dry. Adhering dirt residues are to be removed in particular with a wire brush or compressed air. Wet flanks can be dried with hot air.

Bei größerer Einbaulänge kann maschinellen Geräten der Vorrang zu gegeben werden.For larger installation lengths, priority can be given to mechanical devices.
