Process for repairing road surfacing systems, in particular for open-pore asphalts

摘要

The present invention relates to a process for repairing top layers for roads, tracks, and other areas used by traffic, by applying an amount of at least 20 g/m2 of a polymeric material to the damaged site, applying an amount of at least 80 g/m2 of a first polyurethane reaction mixture (which can comprise additives) to the polymeric material, and applying, to the first polyurethane reaction mixture, a mixture comprising mineral aggregate and a second polyurethane reaction mixture, and allowing the material to harden. The present invention further relates to a repair kit for repairing top layers for roads, tracks, and other areas used by traffic.

1. A process for repairing a top layer of a road, a track, or an area used by traffic, the process comprising:
applying an amount of at least 20 g/m2 (grams per square meter) of a polymeric material to a damaged site to form a polymeric material layer, applying an amount of at least 80 g/m2 of a first polyurethane reaction mixture to the polymeric material to form a first polyurethane reaction mixture material layer on said polymeric material layer, applying, to the first polyurethane reaction mixture layer, an aggregate mixture comprising a mineral aggregate and a second polyurethane reaction mixture, wherein a proportion of the second of polyurethane reaction mixture is from 1 to 10% by weight based on a total weight of mineral aggregate and second polyurethane reaction mixture, and allowing the polymeric material, the first polyurethane reaction mixture, and the second polyurethane reaction mixture to harden, wherein said polymeric material layer and said first polyurethane reaction mixture layer do not contain mineral aggregate.
