Westwood Wecryl rolled surfacing for A2 motorway

Westwood Liquid Technologies Wecryl 420 rolled surfacing system has been used to refurbish and repair A2 motorway, near Erstfeld, Switzerland. In the past any repairs of damaged and worn surfaces as well as of minor damage to the road had mostly been carried out using bitumen-based or bitumenemulsion- based products. Due to the uncontrollable ultimate strength, such products meant that sections of the road had to be closed for prolonged periods. Furthermore, the life of such bitumen-based partial repairs is limited on account of the changes in weather conditions and the volume of traffic.

WestWood has developed several rapid and economical solutions for the refurbishment of road surfaces, and has already carried out many refurbishment projects with reference sections in recent years. For this particular project, superficial damage to the MR 8 road surfacing. The depth of the damaged areas varied from 5 to 30 mm. After the damaged areas had been
cleaned, they were pre-profiled with Wecryl 242 Mortar or Wecryl 420 Rolled Surfacing.

The areas to be repaired were then measured out and concrete masking tape applied to the edges. For the top coat that has to withstand rolling traffic, Wecryl 420 Rolled Surfacing was topped with hard material, grain size 0.6 to 0.9 mm. After just approx. 45 minutes the areas were ready to be walked on and soon the section of road could be reopened to rolling traffic as well.
