This European Standard specifies requirements of Asphalt for Ultra-Thin-Layers (AUTL) for use on roads, airfields and other trafficked areas. AUTL is a hot mix asphalt road surface course laid on a bonding layer, at a nominal thickness between 10 mm and 20 mm with properties suitable for the intended use. The method of bonding is an essential part of the process and the final product is a combination of the bonding system and the bituminous mixture. The method of bonding of AUTL is out of the scope of this European Standard. Mixtures utilizing bitumen emulsion and bituminous materials based on in situ recycling are not covered by this standard. 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.
