Around 95 % of classified highways are constructed with an asphalt surfacing layer. The construction class and thus the road pavement design are selected according to the traffic loading. This ensures that a solution can be found that is tailored to the loading conditions and is both technically satisfactory and economically justifiable. The rapid increase in car and HGV traffic in recent years has led to increasing levels of road damage.
The consequences of poor road conditions are ever shorter maintenance intervals, localised cases of overloading, traffic restrictions and accident blackspots.
To combat these effects, “technical textiles” such as asphalt reinforcement grids have been successfully employed in road construction since the 1980s. In the meantime, a wealth of experience has been compiled in the form of technical recommendations for the use of asphalt inlays and in regulations such as the FGSV Working Paper No. 69. BEBIT is our product range that has been developed in line with these principles.
BEBIT G is a woven grid that has high tensile strength and is made of glass fibres with a melting point above 850 °C. The fibre bundles are encased in a bitumen coating.
Asphalt reinforcement materials are also used in situations where asphalt layers are subject to extreme fluctuations in temperature, since these conditions are liable to promote crack formation. Asphalt sealing systems in water engineering, landfill sites and agricultural silo systems are thus also suitable fields of application for BEBIT Asphalt Reinforcement Grids.
BEBIT G Asphalt Reinforcement Grids are available in different strength categories ranging from 50 kN/m to 200 kN/m. The choice of strength category depends on the type of application, the type of damage, and the traffic loading.
Several factors play a decisive role in the selection of BEBIT G Asphalt Reinforcement Grids. These factors include:
