What is BS EN 13108-7 - Material specifications for porous asphalt about?
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.
Who is BS EN 13108-7 - Material specifications for porous asphalt for?
BS EN 13108-7 on porous asphalt is useful for:
- Manufacturers and suppliers of bituminous mixtures
- Construction industry
- Civil engineers and contractors
- Road, pavement, and highway construction companies
- Repair and maintenance companies
- Local authorities
- Testing laboratories
Why should you use BS EN 13108-7 - Material specifications for porous asphalt?
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.
What is changed since the last update?
BS EN 13108-7:2016 supersedes BS EN 13108-7:2006 which is withdrawn.
BS EN 13108-7:2016 includes some technical changes with respect to BS EN 13108-7:2006.
These include:
- New properties introduced (resistance to deformation, low temperature properties, friction after polishing)
- Additional optional sieves for the characterization of the grading
- For several properties additional categories are introduced
- Possibility to define specific conditions in documents related to the application of the product
- CPR reference and new Annex ZA according to CPR rules
