This method is suitable for repairing damage to asphalt surfaces including potholes, frost heave, sinking, eruptions at the edge of the road surface, thinning of the surface layer and fine cracks. It can be used to repair damage sustainably, thereby maintaining safety for road traffic and renovating the road surface. The road surface can also be prepared for further surfacing work.

A - Blow clean

Dust and dirt is removed from the damaged area with compressed air or additionally with a water-spray attachment.

B - Spray with binder

The cleaned surface is evenly sprayed with a bitumen emulsion to create the best possible bond with the base surface.

C - Fill with a mix of emulsion/chippings

Bitumen emulsion and twice crushed and screened chippings is mixed in the mixer head and delivered into the pothole using compressed air. With larger holes, 4/8 or 6/10 chippings are used in the deeper section, and towards the surface 2/4 chippings are used.

D - Grit spreading

To prevent the chippings adhering to vehicle tires once the road is re-opened to traffic, fine chippings 2/4 are sprinkled on the repaired surface.
Compaction - Right after repair of the damaged area roll and compaction with an asphalt compactor - Reduction of loose chippings.
