1. How to install Fortifix®?

Step by step:

  1. Mill the surface or apply a primer to smooth rough edges. Potholes and open cracks must be treated separately.
  2. Clean and dry the surface thoroughly with a high-pressure washer with vacuum. The surface must be dry before moving on the next step.
  3. Apply a bitumen emulsion, preferably polymer modified, onto the dry surface. Use residual bitumen of at least 650 gr/m².
  4. Unroll Fortifix® manually or automatically, onto the wet tack coat. Assure that the mesh lays completely flat. Make sure that the reinforcement is fixed to the surface before moving to the next step.
  5. Spread about 100 g/m² of aggregates onto Fortifix® interlayer to reduce alleviate 'sticking' of construction tires.
  6. After the breaking of the emulsion, cover Fortifx® with a thin layer of hot asphalt. We recommend an overlay of minimum 3,5 cm.

2. How to install Mesh Track®?

Step by step:

  1. Mill the surface or apply a levelling course in case of severe damages. Fill and compact major cracks.
  2. Clean and dry the surface thoroughly with a high-pressure washer with vacuum. The surface must be dry before moving on to the next step.
  3. Unroll Mesh Track® on the dried surface. Always start from the top.
  4. Cut the edge wire approximately every 10m to facilitate the flattening.
  5. Put the beginning of the second roll under the end of the first roll. When rolled out use maximum 1 mesh overlay longitudinal. Avoid overlapping of transverse flat bars. When rolled out transversal use a 30 cm overlap.
  6. Flatten with a rubber-tired roller. Do not tension the mesh as this may cause it to wave. Start in the middle of the roll and continue until the mesh is completely flat.
  7. Fix the very first transverse bar with nails before slurry seal operation.
  8. Apply slurry seal with a dosage of 20 – 25 kg/m². Use a modified bitumen emulsion slurry.
     


3. Where to place Mesh Track® within the road structure?

We advise to put Mesh Track® not under the top layer, but deep into the structure. It will simplify future road works when replacing the road completely.
