This European Standard specifies requirements for mixtures of the mix group Asphalt Concrete for Very Thin Layers for use on roads, airfields and other trafficked areas. Asphalt Concrete for Very Thin Layers is a bituminous material, of which the composition and the grading of the aggregate is selected for application of the material in very thin layers with a thickness of 20 mm to 30 mm. Mixtures utilizing bitumen emulsion and bituminous materials based on in situ recycling are not covered by this standard. Asphalt Concrete for Very Thin Layers is used for surface courses. This European Standard includes requirements for the selection of the constituent materials. It is designed to be read in conjunction with EN 13108-20 and EN 13108-21.<\/p>\n
