    Patent number: 9221996
    Abstract: 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.
