ArmourScreed (Asphalt Surface Repairs)

ArmourScreed is used to repair defects in asphalt surfaces. When a crack reaches the point where it can no longer simply be crack-chased or overbanded, for example where a section of surface has become an isolation point that could lift under load, it provides a structural repair rather than a surface seal.

In our experience, it works better than overbanding on failed asphalt because overbanding only bridges the defect, whereas ArmourScreed reinstates the surface so it carries load again. The area is cut out and cleaned back to a sound, dry base before the repair is laid, so the finished surface is fully bonded rather than sitting on a compromised section.

Applications: Asphalt surfaces.

The question on any cracked asphalt surface is whether the material either side of the crack is still sound. If it is, the crack is chased, sealed and overbanded, which is quicker and costs less. If the surface around it has broken up, lost its support or started to move under a wheel, sealing only hides the problem for a season, and the section needs cutting out and reinstating with ArmourScreed.

The repair is marked out to sound material on every side, so the new surface bonds to asphalt that will carry load rather than to the edge of the failure. To price it we need the location, the rough area and number of defects, and the working window available, whether that is a weekend in a car park or a night closure on a service road.

There is more on when overbanding is the wrong answer, and on our other surface repair work.
