BS EN 13108-2 specifies requirements for mixtures of the mixed 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 are selected for application of the material in very thin layers with a thickness of 20 mm to 30 mm.
Asphalt Concrete for Very Thin Layers is used for surface courses.
BS EN 13108-2 includes requirements for the selection of the constituent materials.
Note1: Mixtures utilizing bitumen emulsion and bituminous materials based on in situ recycling are not covered by BS EN 13108-2.
Note2: BS EN 13108-2 is designed to be read in conjunction with EN 13108-20 and EN 13108-21.
BS EN 13108-2 on asphalt concrete for very thin Layers (BBTM) is useful for:
The aim of BS EN 13108-2 is to enable specification of asphalt concrete for very thin Layers mixtures on a performance basis. BS EN 13108-2 covers a large variety of materials for different applications, traffic, and climate conditions. BS EN 13108-2 also gives properties and listings of possible categories. The menu approach for properties has been chosen so as to accommodate the road industry for all of Europe. BS EN 13108-2 compliant material specifications of asphalt concrete for very thin Layers mixtures can help reduce asphalt viscosity and reduce the time emulsified asphalt takes to set.
