BEBIT Asphalt Reinforcement Grids

The advantages of BEBIT Asphalt Reinforcement Grids

  • Improves the fitness for use of asphalt-bound traffic surfaces
  • Absorbs and dissipates stresses within the plane
  • Fast and cost-effective to lay
  • Good milling properties
  • Milled material can be completely recycled
  • Extends the maintenance intervals
  • Reduces rehabilitation costs in the long term
  • Complete solution with functional reliability


  • Rehabilitation of asphalt-bound traffic surfaces with various types of cracking (transverse, longitudinal and crazing cracks)
  • Prevents reflection cracking
  • Rehabilitation of concrete road surfaces (on a bituminous regulating course)
  • Laying covering layers over connections, seams and joints


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:

  • Variables and constraints
  • The type of use of the traffic surface and the type and extent of any existing damage

Installation of BEBIT Asphalt Reinforcement Grids

  1. Before installation can begin, the surface on which the grids are to be laid must be checked to ensure adequate evenness and must be also be cleaned. If any cracks, joints or other holes become visible, these must be sealed.
  2. Immediately before laying the asphalt reinforcement, the clean, dry subsurface must be sprayed with a polymer-modified bitumen emulsion of grade C60BP1-S in accordance with TL BE StB 07.
    The subsurface temperature should not be less than 5 °C and the air temperature must be at least 10 °C during laying.
  3. 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.
  4. 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.
