Features

  • Increases the load-bearing capacity
  • Measurable improvement of the structural value due to high tensile strength at small elongation
  • Minimises crack formation and prevents crack reflection
  • Reduces fatigue and thermal cracks
  • Grid structure freely moveable through heat application (no fixed knots)
  • Local application on existing cracks/joints or complete surface application
  • No waiting time - immediate road construction possible
  • Lower consumption of tack coat thanks to the pre-bituminised grid
  • Easy and efficient application with unrolling equipment (also in curves)
  • Effectiveness at a cover layer of min. 2 cm
  • Can be milled and recycled without problems

Application

  • Used against cracking
  • Prevents crack reflection
  • Increases the durability of asphalt surfaces
  • Increases the load bearing capacity of asphalt surfaces
  • The pre-bituminisation guarantees the required layer bonding between old and new road surfaces

Installation Instructions

  • - Clean substrate free of dust and grease
    - Apply polymer modified emulsion on dry surface
    - Apply S&P Carbophalt® G on dry surface by machine or manually, if possible immediately before pavement construction.
    - Apply at temperatures > 3 °C. The minimum temperatures cf. SN 640 430b apply for application of layers.
    - Observe overlapping lengths of 10 to 20 cm
    - Overlapping of reinforcement should be optimised according to the nature and location of joints and cracks, as well as wheel loading.
    - If the S&P grid is applied only on local areas, it must be covered manually with bituminous mixture. This prevents the cracking caused by passing vehicles.
    - Minimum cover layer thickness of 2 cm on top of S&P Carbophalt® G
