Bitufor / Mesh Track

Steel reinforcing overlay

Mesh Track is a steel reinforcing overlay for cracked or deformed roads, which has been successfully used for some years. Used in combination with a Slurry Seal it can deal with problems such as reflective cracking, slippage, deformation or differential movement.

The woven hexagonal wire netting, manufactured out of heavy galvanised steel wire, is reinforced at regular intervals by transverse twisted steel wire stands, interwoven into the mesh. The construction of Mesh Track allows the product to be securely tensioned whilst deformation is prevented by the transverse wire stands.




Application:

The galvanised steel mesh is laid directly onto the surface of the road, which should be cleaned. However, if there are deep deformations in the road surface or heavy damage such as rutting then a regulating layer should first be applied.

The mesh is unrolled onto the surface and flattened to it by a roller. The mesh is then fixed using hilty type nails after, which a Modified Bitumen Emulsion Slurry is applied. Once the slurry has hardened the Asphalt, Bitmac or cold laid Macadam can be laid over with a minimum thickness of 50mm. Depending on design a second layer can be applied, Mesh Track is available in two grades, which limits the deformation in an overlay to a minimum.

    Main Features

  • Limits deformation in an overlay to a minimum.
  • Absorbs the tensile stresses beneath the asphalt layer.
  • Locks asphalt aggregates into the meshes of the netting (compartmentalisation-interlock).
  • Ensures optimal distribution of the load.
  • Provides extra toughness to the overall structure.

Benefits:
  • Transverse reinforcement guarantees an even load distribution.

  • The Asphalt/ Bitmac/ Cold Laid Macadam aggregates are locked solidly into the large hexagonal mesh.

  • The slurry offers extra elasticity to the interface and better absorbs the strain in overlays.

  • Prevents water penetrating into the subgrade.

  • Mesh track is flexible and easy to lay.

  • Steel is intrinsically much stronger as a reinforcing material than plastic, glass fibre etc

  • Provides extra toughness to the overall structure.
