Description

Zwischenschicht zwischen einer Betonunterlage und einem Gußasphaltbelag Die Erfindung betrifft eine Zwischenschicht zwischen einer Betonunterlage und einem Gußasphaltbelag.Intermediate layer between a concrete base and a mastic asphalt surface The invention relates to an intermediate layer between a concrete base and a Mastic asphalt surface.

Beim Verlegen von Gußasphalt auf Beton tritt eine Blasenbildung ein, deren Ursachen nicht im Asphaltmaterial liegen, sondern die nach den neuesten Erkenntnissen durch mechanische Kräfte verursacht wird, welche sich zwischen dem Gußasphalt und der darunterliegenden Betonschicht auswirken. Diese mechanischen Kräfte werden durch die Dampfspannung der Feuchtigkeit zwischen dem Gußasphalt und seiner Betonunterlage hervorgerufen.When laying mastic asphalt on concrete, bubbles form, the causes of which do not lie in the asphalt material, but those based on the latest findings is caused by mechanical forces, which are between the mastic asphalt and the underlying concrete layer. These mechanical forces are through the vapor tension of moisture between the mastic asphalt and its concrete base evoked.

Man hat bereits nach Mitteln gesucht, um diese Dampfspannung unwirksam zu machen. Ein derartiges Mittel besteht darin, daß man den Gußasphalt nicht auf dem glatten Beton verlegt, sondern daß man zwischen Beton und Gußasphalt eine grobporige Betonschicht einschaltet. Durch diese grobporöse Zwischenschicht werden die entstehenden Wasserdampfdrücke abgeleitet. Diese Maßnahme ist jedoch praktisch nur bei Neubauten anwendbar, weil die grobporöse Zwischenschicht eine Mindeststärke von etwa 25 mm haben muß, um zu dem gewünschten Erfolg zu führen.Means have already been sought to make this vapor tension ineffective close. One such means is that you do not use the mastic asphalt laid the smooth concrete, but that you have a coarse-pored between concrete and mastic asphalt Concrete layer turns on. The resulting Water vapor pressures derived. However, this measure is only practical for new buildings applicable because the coarse-pored intermediate layer has a minimum thickness of about 25 mm must have in order to lead to the desired success.

Ein anderer bekannter Vorschlag zur Vermeidung der Blasenbildung besteht darin, zwischen den Gußasphalt und die Betonschicht eine Zwischenlage von Papier einzuschalten. Hierbei soll das Kapillarsystem des Papiers die gleiche Wirkung haben wie die vorstehend erwähnte Zwischenschicht aus grobporigem Beton. Diese Maßnahme ist zwar überall anwendbar, sie hat jedoch den erheblichen Nachteil, daß die Zwischenschichten aus Papier bzw. Pappe durch Feuchtigkeitsaufnahme mit der Zeit verrotten sowie ferner schleimig und porenarm werden, wodurch sie ihre Wirkung als Drainage verlieren.Another well-known suggestion for avoiding blistering exists in it, between the mastic asphalt and the concrete layer, an intermediate layer of paper to turn on. Here, the capillary system of the paper should have the same effect like the one above mentioned intermediate layer of coarse-pored concrete. Although this measure can be used everywhere, it has the significant disadvantage that the intermediate layers of paper or cardboard through moisture absorption with rot over time and also become slimy and poor in pores, which makes them their Lose effectiveness as drainage.

Die Erfindung bezweckt die Beseitigung der Nachteile der bekannten Verfahren zum Aufbringen von Gußasphalt auf Beton unter Einschaltung einer porösen Zwischenschicht und die Schaffung eines Verfahrens, welches nicht nur überall anwendbar ist, sondern durch welches auch für die normale Lebensdauer des Gußasphalts die Drainagewirkung der Zwischenschicht unverändert erhalten bleibt.The invention aims to eliminate the disadvantages of the known Method for applying mastic asphalt to concrete with the inclusion of a porous Interlayer and the creation of a process that is not only applicable everywhere is, but by which also for the normal lifespan of the mastic asphalt The drainage effect of the intermediate layer remains unchanged.

Der Erfindungszweck wird dadurch erreicht, daß als Trennschicht ein Mineralfaservlies, z. B. ein Glasvlies, verlegt wird, welches keine verrottbaren Stoffe enthält.The purpose of the invention is achieved in that a separating layer Mineral fiber fleece, e.g. B. a glass fleece is laid, which does not rot Contains substances.

Da die Trennschicht praktisch unverrottbar ist und keine Feuchtigkeit binden kann, bleibt sie praktisch unbegrenzte Zeit wirksam. Durch die Porosität der Trennschicht ist sie ferner für die auftretenden schädlichen Dampfdrücke durchlässig, so daß die unter Verwendung einer Zwischenschicht nach der Erfindung verlegten Gußasphalte keine Blasenbildungen mehr aufweisen.Because the separating layer is practically non-rotting and has no moisture can bind, it remains effective for a practically unlimited time. Because of the porosity the separating layer is also permeable to the harmful vapor pressures that occur, so that the poured asphalt laid using an intermediate layer according to the invention no longer show any blistering.
