BS EN 13108-7 discusses material specifications of bituminous mixtures. BS EN 13108-7 specifies requirements for mixtures of the mix group porous asphalt for use on roads, airfields, and other trafficked areas. Porous asphalt is used for surface courses. Porous asphalt can be laid in more than one layer.
BS EN 13108-7 includes requirements for the selection of the constituent materials.
Note 1: The mixtures of the mix group porous asphalt are produced on the basis of hot bitumen. Mixtures utilizing bitumen emulsion and bituminous materials based on in situ recycling are not covered by BS EN 13108-7.
Note 2: BS EN 13108-7 is designed to be read in conjunction with BS EN 13108‑20 and BS EN 13108‑21.
BS EN 13108-7 on porous asphalt is useful for:
Porous asphalt is characterized by high porosity, consequently a high macro roughness, a lower thermal conductivity, a strong permeability to water, and less contact points between the stones in comparison to the traditional dense graded mixes. BS EN 13108-7 is detailed best practices to ensure bituminous mixtures meet the quality and performance requirements that impart structural stability and durability to your construction works. The aim of BS EN 13108-7 is to enable the specification of porous asphalt mixtures on a performance basis. BS EN 13108-7 covers a large variety of materials for different applications, traffic, and climate conditions. BS EN 13108-7 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 13108-7 compliant material specifications of porous asphalt can help reduce asphalt viscosity and reduce the time emulsified asphalt takes to set.
