FIELD: chemistry.

SUBSTANCE: invention relates to an adhesive film for road surface. The adhesive film contains a carrier substrate which is a polymer film, a surface layer on the substrate surface made from a polymer film and a layer of pressure-sensitive hot-melt adhesive. The polymer film is based on polyvinyl chloride, polyamide, acrylic resins, high-density polyethylene, polypropylene and polyethylene vinyl acetate. The surface layer contains resinous non-asphalt material or material which contains about 50% or more resinous non-asphalt component and about 50% or less asphalt component. The surface layer can form a bond with the adjoining layer of asphalt road material when the surface layer is heated to about 120°C or higher at pressure which is applied to the material of the adhesive film on the side of superimposed layer of asphalt road material. The layer of asphalt road material has thickness of about 3.8 cm or more. The surface layer is not adhesive at temperature of about 20°C and pressure of about 1 atm. The adhesive film for road surface can be used particularly for repairing old road surfaces without tack coat.

EFFECT: improved technical properties of the adhesive film for road surface.
