General

Der überwiegende Teil der Straßen im klassifizierten Straßenbau wird mit Asphaltdecken ausgeführt. Durch stetig steigende Verkehrs- und Schwerlastbelastungen kommt es dabei zunehmend zu vorzeitigen Schäden, verkürzten Wartungsintervallen und Einschränkungen der Gebrauchstauglichkeit. Um diesen Beanspruchungen dauerhaft entgegenzuwirken, werden seit vielen Jahren technische Textilien wie Asphaltarmierungsgitter eingesetzt, die sich im Asphaltstraßenbau bewährt haben und die Grundlage der Produktreihe BEBIT bilden.

BEBIT G sind hoch zugfeste Gitter aus Glasfasern mit einer Schmelztemperatur von über 850 °C. Eine bituminöse Beschichtung umhüllt die Faserbündel. BEBIT G Asphaltarmierungsgitter haben einen extrem hohen Steifemodul, der eine unmittelbare, hohe Zugkraftaufnahme bei geringsten Dehnungen gewährleistet. Dadurch kommt es zur Spannungskonzentration in der Asphalteinlage und zu einer sofortigen Aktivierung der bewehrenden Funktion. Die offene Struktur von BEBIT G ermöglicht einen optimalen Schichtenverbund.

Asphalt reinforcement grid with additional installation aid

BEBIT G plus and BEBIT G BC sind Asphaltarmierungsgitter der Reihe BEBIT G mit zusätzlicher Verlegehilfe. Beim Produkt BEBIT G Plus ist die Verlegehilfe eine zusätzliche Maschenfüllung aus feinen Glaslunten, wogegen beim Typ BEBIT G BC ein leichter Vliesstoff zum Einsatz kommt.

A laying aid ensures maximum possible contact with the bituminous subsurface, keeps the grid firmly in position and makes installation more cost-efficient. No additional bitumen emulsion or otherwise customary spreading of chippings is necessary.

Functions

Reinforcement

BEBIT asphalt reinforcement grids are reinforcement products. The grid acts as a reinforcing element that absorbs the forces in the area of loading and thus effectively delays crack development. The resulting fatigue resistance is greater than that of a non-reinforced asphalt layer. The reinforcement grid improves the load-bearing capacity of the entire pavement system, slows down the propagation of cracks from the substrate and significantly extends the useful life of the asphalt surface.

Applications

Asphalt reinforcement products are useful in all situations where asphalt layers are subject to high traffic loads and temperature fluctuation, since these conditions are liable to promote crack formation. Asphalt sealing systems in water engineering, landfill sites and agricultural areas are thus also suitable fields of application for BEBIT Asphalt Reinforcement Grids. BEBIT Asphaltarmierungsgitter.

Installation

Prior to installation the eveness of the installation surface must be checked and the substrate cleaned. If any cracks, joints or other openings become visible, these must be filled.
The subsurface temperature must not be less than 5 °C and the air temperature must be at least 10 °C during installation.
BEBIT asphalt inlays must be laid into the bitumen emulsion layer after the emulsion has broken. They must be laid in dry weather only and without creasing.
Immediately before the asphalt reinforcement is laid, the road surface is first sprayed with a Class C70BP 3-OB-1 polymer-modified bituminous emulsion tack coat, in accordance with TL BE StB 07. Good experience has also been had with Class C70BP 3-OB-2 emulsions. If any other type of emulsion is to be used, this must be tested in advance to make sure that good bonding with the supporting layer is achieved.
A road surfacing layer of at least 40 mm must be laid on top of the asphalt inlay immediately after the bitumen emulsion has dried.
