Abstract

The bonding and insulating layer between the floor slab and the bituminous surface is a layer of curing plastic, into which is introduced, before curing, a granulate of thermoplastic or elastic polymers, the melting point of which is below the application temperature of the bituminous mixture. The polymers must be compatible with bitumen and with the curing plastic. This ensures not only a positive connection, but also an additional bonding of the plastic layer with the bituminous surface and a sealing of possible hairline cracks which occur.

Description

Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von bituminösen Fahrbahndecken auf Brücken mit Fahrbahnplatten aus Metall oder Beton, bei denen zwischen der Fahrbahnplatte und der Fahrbahndecke eine oder mehrere Haft-und Isolierschichten aus aushärtendem Kunststoff aufgebracht werden, wobei zumindest in der oberen Schicht vor dem Anhärten ein Granulat eingestreut wird.The invention relates to a method for producing bituminous pavement ceilings on bridges with pavement slabs made of metal or concrete, in which one or more adhesive and insulating layers made of hardening plastic are applied between the pavement slab and the pavement slab, at least in the upper layer before Hardening is sprinkled with granules.

Brücken in Stahl-oder Stahlbetonbauweise werden mit Fahrbahndecken aus bituminösem Mischgut versehen. Bei diesen bituminösen Belägen können Risse auftreten, so daß Regen-und Tausalzwasser eindringen und die Fahrbahnplatten zerstören können. Es werden daher Isolierschichten aus aushärtendem Kunststoff auf die Fahrbahnplatten aufgebracht, um diese vor der Korrosion zu - schützen. Da die Haftung zwischen der ausgehärteten Kunststoffschicht und den Asphaltschichten aber meist gering ist, wird die Oberfläche der Kunststoffschicht aufgerauht, um eine formschlüssige Verbindung zu erhalten.Bridges in steel or reinforced concrete construction are provided with pavements made of bituminous mix. Cracks can occur with these bituminous coverings, so that rainwater and de-icing salt water can penetrate and destroy the pavement slabs. Insulating layers made of hardening plastic are therefore applied to the carriageway slabs to protect them from corrosion. However, since the adhesion between the hardened plastic layer and the asphalt layers is mostly low, the surface of the plastic layer is roughened in order to obtain a positive connection.

So wird in der DE-PS 840 400 vorgeschlagen, in die noch flüssige Kunststoffschicht Splitt oder Stahlspäne einzustreuen. Infolge ihrer hohen Dichte sinken diese Granulate jedoch bis auf die Fahrbahnplatten. Dadurch entstehen Undichtigkeiten in dem Isolierbelag.For example, DE-PS 840 400 proposes to sprinkle grit or steel chips in the still liquid plastic layer. However, due to their high density, these granules sink to the pavement slabs. This creates leaks in the insulating covering.

Um dies zu verhindern, wird in der DE-PS 12 40 547 eine zweilagige Kunststoffschicht aus einer Isolierund und einer Haftschicht, in die Splitt eingestreut ist, vorgeschlagen. Wegen des hohen Aufwandes wird in der DE-PS 22 23 641 eine Gewebebahn in die noch flüssige Kunststoffschicht eingelegt, um so das Durchsinken des Splittes zu verhindern. Da auch dieses Verfahren noch zu aufwendig erschien, wurde in der DE-OS 24 50 987 vorgeschlagen, einen Kunststoff mit thixotrop eingestelltem Fließverhalten zu verwenden.In order to prevent this, DE-PS 12 40 547 proposes a two-layer plastic layer consisting of an insulating and an adhesive layer, into which chippings are scattered. Because of the high expenditure, a fabric web is inserted into the still liquid plastic layer in DE-PS 22 23 641, in order to prevent the grit from sinking through. Since this method also appeared to be too complex, it was proposed in DE-OS 24 50 987 to use a plastic with a thixotropic flow behavior.

Die Haftung zwischen Kunststoffschicht und Asphalt läßt sich außerdem durch mechanisches Verformen der Kunststoffoberfläche wie beispielsweise durch Einwalzen von Rillen (DE-PS 850 458) verbessern oder durch Einlegen einer Verstärkungslage aus einem ungewebten Material, dessen unterer Teil von dem flüssigen Kunststoff und dessen oberer Teil von dem Bitumen durchdrungen wird (DE-OS 27 91 885).The adhesion between the plastic layer and asphalt can also be improved by mechanically deforming the plastic surface, such as by rolling grooves (DE-PS 850 458) or by inserting a reinforcing layer made of a non-woven material, the lower part of which is made of the liquid plastic and the upper part of which the bitumen is penetrated (DE-OS 27 91 885).

In der DE-OS 25 15 168 wird der bessere Verbund durch eine Verankerungszwischenlage mit aus Kunstharzmörtel geformte Noppen oder Rippen erreicht. Auch dieses Verfahren ist sehr aufwendig.In DE-OS 25 15 168 the better bond is achieved by an anchoring intermediate layer with knobs or ribs formed from synthetic resin mortar. This process is also very complex.

Wie in der DE-OS 23 54 913 ausgeführt, können in den Isolier-und Haftschichten Haarrisse entstehen. Dies mag verschiedene Ursachen haben. Unterschiedliche Wärmeausdehnungskoeffizienten und verschiedene Elastizitätsmoduli der Fahrbahnplatten einerseits und der Kunststoffschicht andererseits sind sicherlich auch als Gründe für das Entstehen von Haarrissen anzusehen.As stated in DE-OS 23 54 913, hairline cracks can occur in the insulating and adhesive layers. There may be several reasons for this. Different coefficients of thermal expansion and different moduli of elasticity of the road slabs on the one hand and the plastic layer on the other hand are certainly also to be regarded as reasons for hairline cracks.

In der DE-OS 23 54 913 wird daher eine zweilagige Kunststoffbeschichtung mit eingestreutem Splitt vorgeschlagen, bei der ein nach nach dem Erwärmen auf 240°C elastisch bleibender Kunststoff verwendet wird. Auch dieses Verfahren ist sehr aufwendig und schränkt die Auswahl der geeigneten Kunststoffe stark ein.DE-OS 23 54 913 therefore proposes a two-layer plastic coating with sprinkled grit, in which a plastic that remains elastic after heating to 240 ° C. is used. This process is also very complex and severely limits the selection of suitable plastics.

Der Erfindung liegt die Aufgabe zugrunde, ein neuartiges Verfahren zur Herstellung von Fahrbahndecken zu entwickeln, bei denen die vorerwähnten Schwierigkeiten vermieden werden und neben einer ausgezeich neten Haftung zwischen Kunststoffschicht und bituminösen Deckschichten eine Elastifizierung der Grenzschicht erreicht wird, so daß entstehende Haarrisse überbrückt werden.The invention has for its object to develop a novel method for the production of road surfaces, in which the aforementioned difficulties are avoided and in addition to an excellent adhesion between the plastic layer and bituminous outer layers, an elasticization of the boundary layer is achieved so that hairline cracks are bridged.

Die Aufgabe wird dadurch gelöst, daß das Granulat aus mindestens einem bei der Einbautemperatur des bituminösen Mischgutes im geschmolzenen Zustand befindlichen, mit dem Bitumen und der Kunststoffschicht sich verbindendem Material besteht.The object is achieved in that the granules consist of at least one material which is in the molten state at the installation temperature of the bituminous mixture and which binds to the bitumen and the plastic layer.

Als aushärtende Kunststoffe für die Haft-und Isolierschicht werden bevorzugt lösungsmittelfreie Epoxidharzsysteme mit geeigneten Härtern und Polyurethanharze bzw. ihre jeweiligen Teer-oder Bitumenkombinationen verwendet, die gegebenenfalls mit Füllstoffen versehen sind. Aber auch andere, dem Fachmann bekannte, aushärtende Kunststoffe können benutzt werden.Solvent-free epoxy resin systems with suitable hardeners and polyurethane resins or their respective tar or bitumen combinations, which are optionally provided with fillers, are preferably used as the hardening plastics for the adhesive and insulating layer. However, other curing plastics known to the person skilled in the art can also be used.

Die Granulate bestehen aus thermoplastischen oder elastischen Polymeren oder ihren Bitumenkombinationen und weisen einen Schmelzpunkt im Bereich von etwa 40 -150°C auf, vorzugsweise zwischen 70 und 120°C. Der Schmelzpunkt muß auf den vorgesehenen bituminösen Belag abgestimmt sein. Beim Einbau von Walzasphalt mit einer Einbautemperatur von maximal 150°C werden Granulate mit Schmelztemperaturen zwischen 70 und 80°C bevorzugt, beim Einbau von Gußasphalt mit etwa 100°C höheren Einbautemperaturen solche mit einem Schmelzpunkt zwischen 100 und 120°C.The granules consist of thermoplastic or elastic polymers or their bitumen combinations and have a melting point in the range of approximately 40-150 ° C., preferably between 70 and 120 ° C. The melting point must be matched to the intended bituminous covering. When installing rolled asphalt with a maximum installation temperature of 150 ° C, granules with melting temperatures between 70 and 80 ° C are preferred, while with poured asphalt with installation temperatures around 100 ° C higher, those with a melting point between 100 and 120 ° C are preferred.

Der chemische Aufbau der Kunststoffgranulate muß so sein, daß eine gute Verträglichkeit sowohl mit dem aushärtenden Kunststoffsystem der Haft-und Isolier schicht, wie z.B. Teer-Epoxidharz-Kombinationen mit überwiegend aromatischen Strukturen, als auch mit den aliphatischen Strukturen der bituminösen Beläge besteht.The chemical structure of the plastic granules must be such that they are well compatible with both the hardening plastic system of the adhesive and insulating layer, e.g. Tar-epoxy resin combinations with predominantly aromatic structures, as well as with the aliphatic structures of the bituminous coverings.

Diese Anforderungen erfüllen z.B. Polyvinylacetate, Polyvinylpropionate, Copolymerisate aus Vinylacetat oder Vinylpropionat mit Ethylen, Homo-und Copolymerisate aus Alkylacrylaten mit Ethylen, Propylen, Acrylsäure, Maleinsäure, Styrol-oder Acrylnitril. Die Homo-oder Copolymerisate können entweder in reiner Form oder in Abmischung mit anderen Polymeren, mit Bitumen, Naturharzen, oligomeren Kohlenwasserstoffharzen, Synthesekautschuk oder Weichmachern Verwendung finden.These requirements are fulfilled e.g. Polyvinyl acetates, polyvinyl propionates, copolymers of vinyl acetate or vinyl propionate with ethylene, homopolymers and copolymers of alkyl acrylates with ethylene, propylene, acrylic acid, maleic acid, styrene or acrylonitrile. The homopolymers or copolymers can be used either in pure form or in admixture with other polymers, with bitumen, natural resins, oligomeric hydrocarbon resins, synthetic rubber or plasticizers.

Die Korngröße des Granulats sollte so gewählt werden, daß 90 Gew.-% im Bereich von 1 bis 10 mm, vorzugsweise zwischen 3 und 6 mm liegt.The grain size of the granules should be selected so that 90% by weight is in the range from 1 to 10 mm, preferably between 3 and 6 mm.

Die Fahrbahnplatten werden in üblicher Weise mit einem geeigneten lösungsmittelarmen Primer behandelt, um bei Betonplatten den Staub zu binden bzw. um einer Korrosion bei Stahlplatten vorzubeugen. Nach dem Erhärten des Primers wird in einer Schichtdicke von 1 bis 5 mm, vorzugsweise 2 bis 3 mm, eine Haft-und Isolierschicht aus aushärtendem Kunststoff aufgetragen, in die unmittelbar danach, innerhalb der Gelierzeit, 0,5 bis 1,0 kg/m2 des Granulats eingestreut werden. Wegen seiner geringen Dichte gegenuber Splitt sinkt das erfindungsgemäß verwendete Granulat nur wenig in die Haft-und Isolierschicht ein, so daß es die Oberfläche der Fahrbahnplatte nicht berührt. Nach dem Aushärten kann das nicht gebundene Granulat abgefegt werden. Beim Einbau des bituminösen Mischgutes wird das Granulat geschmolzen und bildet eine homogene kraftschlüssige Verbindung zwischen der Kunststoffschicht und dem Asphalt, die Haarrisse ohne weiteres zu überbrücken vermag. Der Asphalt dringt außerdem in die Vertiefungen der Haft-und Isolierschicht ein und bildet so einen zusätzlichen formschlüssigen Verbund.The road slabs are treated in the usual way with a suitable low-solvent primer in order to bind the dust on concrete slabs or to prevent corrosion on steel slabs. After the primer has hardened, an adhesive and insulating layer made of hardening plastic is applied in a layer thickness of 1 to 5 mm, preferably 2 to 3 mm, into which 0.5 to 1.0 kg / m 2 of the granules are sprinkled. Because of its low density compared to chippings, the granulate used according to the invention sinks only a little into the adhesive and insulating layer, so that it does not touch the surface of the carriageway slab. After curing, the unbound granulate can be swept off. When the bituminous mix is installed, the granulate is melted and forms a homogeneous, force-locking connection between the plastic layer and the asphalt, which is able to easily bridge hairline cracks. The asphalt also penetrates into the depressions in the adhesive and insulating layer and thus forms an additional positive connection.

Durch die Kombination des kraft-und des formschlüssigen Verbundes wird eine Haftung zwischen Kunststoff-und Asphaltschicht erreicht, die die Eigenfestigkeit des Fahrbahnbelages deutlich übertrifft.The combination of the non-positive and the positive connection results in an adhesion between the plastic and asphalt layers, which clearly exceeds the inherent strength of the road surface.

Die Erfindung wird anhand der nachfolgenden Beispiele näher erläutert, ohne darauf beschränkt zu sein.The invention is explained in more detail with reference to the following examples, without being restricted thereto.

Nach dem Aushärten der elastischen Masse wird das nicht eingebundene Granulat abgefegt und in üblicher Weise ein Fahrbahnbelag aus Gußasphalt aufgebracht.1000 g / m 2 of granules with a grain size of 5 to 6 mm of a bitumen-modified ethylene copolymer (Lucobit; BASF), which has a melting point of 95-105 ° C., are sprinkled into the still liquid masses. After the elastic mass has hardened, the non-bound granulate is swept off and a road surface made of mastic asphalt is applied in the usual way.

Nach dem Aushärten des Primers wird die Fahrbahnplatte mit 2 kg/m2 einer lösungsmittelfreien Masse auf der Basis flüssiger Epoxidharze (Orthoflex BC, Strabag-Bau AG) beschichtet. In die noch flüssige Haft-und Isolier - schicht werden 500 g/m2 eines thermoplastischen Granulats auf der Basis eines mit Bitumen modifizierten Ethylencopolymerisats (Lucobit; BASF) mit einer Körnung von 2 bis 3 mm eingestreut, das einen Schmelzpunkt von 95 -105°C hat.
