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 the Road, civil engineering, building and sewer construction, a process for its manufacture as well a procedure for laying the joint tape on a seam / connecting flank 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, civil engineering, building and sewer construction are manufactured in the factory and produce machine-preformed thermoplastic Band profiles of different cross sections are essentially made up of Bitumen or bitumen modifications exist as binders. these can for example additives of plastics, elastomers, plasticizers and contain 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.DE-U 77 28 361 describes a laying device for self-adhesive or fusible Sealing tapes described, but no details on the structure 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 shaped, strapless, bitumen-containing sealing material, for example from a premix of about 15% finely shredded Buna rubber and about 85% mixed bitumen mixed with additional mixed bitumen, oil, Slate flour and modified cellulose powder is mixed. The so shaped In particular, tape is inserted cold and without primer into 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-process joint tape and a method for laying a joint tape. In particular, a joint tape is used described in road construction, which consists of a polymer-modified road construction bitumen exists, which is provided on at least one side with an adhesive layer is. The task is to be solved with this joint tape, a joint tape and a To create a process that involves cold laying, i.e. without the help of a Flame, allows.

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.The application of an adhesive layer described there on the joint tape has however, the disadvantage that on the one hand the shelf life of the joint tape due to the relative instability of the adhesive, in contrast to the bitumen in which Rule can be adversely affected. It also affects one Adhesive layer especially based on SBS / SIS block copolymers Adhesion of the joint tapes to the joint flanks, especially if the joint tape or the seam / connecting flank is heated with a propane gas flame or also by the temperature of the mixed material of the new asphalt or Top layer, which is applied 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 with the present invention is to compare with the prior art technically improved bitumen joint tape for street, low, high and To provide sewer construction. This problem is solved according to the invention in a first embodiment solved 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 before applying the joint tape in generally a bitumen-containing primer or a primer on the seam / connecting flank was sprayed or painted to reduce the adhesion of the joint tape It is to support the attachment and, if necessary, to bind dust with the help of the present invention at appropriate cheap Outside temperatures and clean edges / flanks are usually possible on the To refrain from priming. The application of a primer is at all temperatures dispensable. The joint tape according to the invention remains after pressing with a wooden / metal spatula or another suitable tool on the edge / flank. The invention is based on the fact that in practice - of course in bad weather - is known, with the help of a gas burner, already melt the joint tape on one side to the seam / connecting flank in order to Avoid laying problems. The corresponding are in the prior art Outside temperatures known. The connecting edges are usually folded, cut or preformed and can consist of prefabricated building materials. They have to be 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 done in dry weather and one Surface temperature of the component of +5 ° C. At temperatures up to +/- 0 ° C, the work can be continued if additional measures such as for example, the preheating of the seam and / or the flank has been determined are.

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 with a Assembly aid / Nerlegehilfe is already factory-equipped and in every season even without aids, such as primer / primer or gas flame, on the seam / connecting flank can be pressed and remains until the fresh mix is counter-built 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 enamel coating practically consists of a one-sided coating of the joint tape, which helps to avoid intolerance, primarily at Asphalt or concrete mainly consists of bitumen. In one particularly preferred embodiment of the present invention is the melt coating made of polymer-modified bitumen. Such materials are Those skilled in the art are sufficiently well known.

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 enamel coating is not critical. The layer however, it should be applied as thinly as possible. Particularly preferred in the sense The present invention is to provide the joint tape with a melt coating equip, which comprises 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.According to the invention, the material of the actual bitumen joint tape differs from the bitumen-containing enamel coating. In particular, it is preferred that the bitumen-containing melt coating, for example made of polymer-tempered Bitumen, a higher elasticity, in particular an improved cold bending capacity, an increased cone penetration as well as an increased resilience 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.For the purposes of the present invention, it is particularly preferred 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 follows BS 2499 the melt coating at least 60 to 140 1/10 mm and the Cone penetration of the joint tape is 20 to 50 1/10 mm with the proviso that the difference in the values of cone penetration is at least 20 to 60 1/10 mm is. This ensures that the melt coating adheres to existing ones Bumps better conforms to 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 to better compensate for irregularities in the seam and Connecting flank it is particularly preferred in the sense of the present invention, if the resilience of the melt coating according to BS 2499 at least 60% to 90% and the resilience of the joint tape is 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 enamel coating can also, for example, by the choice of different bitumen can be set. So it is in the sense of the present Invention particularly preferred, the bitumen joint tape made of a polymer-modified Bitumen with a relatively high proportion of fillers and possibly fiber components provide. In contrast, it is preferred for the purposes of the present invention if with the same starting bitumen for the bitumen joint tape and the bitumen-containing Melt coating the mineral content lower, and especially the polymer content is higher in the bituminous enamel coating than in the bitumen joint tape. For the purposes of the present invention, a joint tape is particularly preferred that the bitumen-containing melt coating from 60 wt .-% to 93 wt .-% bitumen consists. Similarly, the joint tape can contain from 60% to 93% by weight 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 enamel coating can be done in different ways be applied to the joint tape. As a state of the art anyway separating paper used is provided, the bitumen-containing enamel coating covers, it may be appropriate, the joint tape according to the invention produce that first a melt coating on a release paper and then apply the joint tape to the back of the enamel coating.

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 manufacturing method, it is possible to First apply the bituminous enamel coating to the joint tape and then 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 help of the present invention a glue during processing of the bitumen joint tape with the seam / connecting flank is not desired, but only holding the joint tape at the desired location can be achieved in the sense of the present invention, it is particularly preferred to use the melt coating not as a continuous surface on the surface of the joint tape apply, but this in the form of a punctiform, possibly grid-shaped Enamel coating. This will in particular material for the Melt coating saved and according to the invention the same holding effect achieved, which also with a continuous large-area enamel coating is achieved. However, a change in location of the joint tape is advantageous possible before the mix is introduced, which does not cause damage of the joint tape. In addition, there is extensive contact of the material given the joint tape with the mix, the only selectively, if necessary interrupted in a grid pattern by small surface portions of the enamel coating is.

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.Another 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 top layer in road construction. According to the invention the joint tape stopped by pressing. It goes without saying to ensure that the enamel coating is in contact with the seam / connecting flank comes.
