How to install Fortifix®?
Step-by-step Installation
- Mill the surface or apply a primer to smooth rough edges. Potholes and open cracks must be treated separately.
- Clean and dry the surface thoroughly, with a high-pressure washer with vacuum if surface has been milled or if it is dirty. The surface must be dry before moving on to the next step.
- Apply a bitumen emulsion, preferably polymer modified, onto the surface. Use at least 650 g/m² of residual bitumen. Note that amount and type bitumen must be adapted to the type and roughness of the surface and environmental conditions.
- Unroll Fortifix®, manually or automatically, onto the wet tack coat. Assure the mesh lays completely flat. Make sure the reinforcement adheres to the surface before moving to the next step.
- Take adequate measures to avoid stickiness to the wheels of the job site traffic, according to the code of practice or existing standards.
- After the breaking of the emulsion, Fortifix® can be covered with a thin layer of hot asphalt. We recommend an overlay of minimum 3,5 cm.
Overlaps
- Place the beginning of a new roll under the end of the previous roll.
- In transversal direction, the overlap should match the length of the free cords.
- Also use overlaps to create curves; cut the mesh in pieces of approx. 5 m and arrange accordingly.
- Overlaps must be sprayed with an emulsion/tack coat whenever a textile carrier extends over another (see also point 3 of ‘Installation’).
Note
- Fortifix® can be applied on both grinded and smooth surfaces.
- Fortifix® can be trimmed to keep manholes and other utility structures uncovered.
- If chippings are used to reduce stickiness to tires after Fortifix® installation, applying approx. 1 kg/m² of dry, dust free chippings (size 4-10 mm) is recommended.
- When prescribed or according to local regulations, an extra SAMI can be used on top.
