BEBITAsphalt Reinforcement

BEBIT Asphalt ReinforcementThe permanently growing traffi c volume and load by transport of goods result in signifi -

cant requirements of the road network. Especially the heavy-duty traffi c with high axis

loads brings a faster and faster wear and tear of the road covering and an abbreviated

usage period with increasing repair work.

Asphalt had already been used for reinforcing traffi c roads in ancient times and has

proven to be a long-lasting construction material in the fi eld of road construction until

today. However, asphalt can take only minor tensile stress. The consequence is a prema-

ture formation of cracks in the new road covering and an increased requirement for repair

work. BEBIT asphalt reinforcement grids counteract against these undesirable symptoms

and offer an economic solution for the traffi c way construction. Fields of application

of BEBIT asphalt reinforcement grids are various. They are applied with asphalt layer

reinforcement, extension of driveway widths, pavement breaking and in areas with high

traffi c load. Furthermore, BEBIT reinforcement grids are used as a precaution to avoid

formation of ruts and with the construction and repair of the surfaces of air traffi c areas.

BEBIT

BEBIT asphalt reinforcement grids are made out of glass fi bers with a melting point of

more than 850˚C due to their specifi c properties, BEBIT G and BEBIT G plus asphalt rein-

forcement grids can take high tensile stress and also qualify for their low elongation.

The occurring tensile stress is taken by BEBIT asphalt reinforcement grids and effectively

absorbed load-distributing over the surface.

BEBIT Product Program BEBIT G, an extra-sturdy reinforcement grid, of low-creep and extremely temperature-

resistant technical glass fi bers. It can absorb high tensile stress already at minor

elongation. The melting point of BEBIT G is at 850˚ C. In addition, the glass fi bers are

recyclable to the effect that milling-off is no problem in case of repair. The re-use of

the recycled asphalt is possible.

BEBIT G plus consists of reinforcing grid BEBIT G. Additionally, it is equipped with a

mesh fi ll made out of voluminous glass fi ber yarns. This additional glass roving acts

as an installation aid and increases together with the bituminous emulsion the

adhesion to the layer surface during the installation. It allows for a faster and more

secure processing without extra mechanical fi xing as well as an excellent layer

compound. Gritting after the installation can be avoided.

Technical Data

Installation Conditions BEBIT asphalt reinforcement grids shall be generally installed between two asphalt

layers. In case this condition is not given, an asphalt-bound intermediate layer has to

be installed prior to installation work.

BEBIT must be installed on leveled base surface. If required, a bituminous equalizing

layer shall be installed before to ensure full-surface contact to BEBIT. A bituminous

emulsion according to our installation guidelines will ensure a solid adhesive com-

pound between the covering layers.

Bituminous emulsions and adhesive tack coats present themselves as environment-

friendly and praxis-oriented solutions.

The installation of BEBIT is ordinarily performed manually (with the assistance of roll-

off devices) or with adequate vehicles. Pre-stressing of the asphalt reinforcing grid,

including full-surface fi xing by connection with bolts, is not required with type BEBIT

G plus.

Detailed installation instruc-

tions can be taken from the

current BEBIT installation gui-

delines and shall be available

to the personnel performing

the work at the construction

site and those persons who

are responsible. The rules and

regulations applicable for the

installation of asphalt layers

will keep their validity with the

installation of BEBIT asphalt

reinforcing grids.
