What is BS EN 12849 - Determination of penetration power of bituminous emulsions about?
BS EN 12849 is the European Standard on bitumen and bituminous binders. The main objective of BS EN 12849 is to ensure bitumen and bituminous binders play a positive role in maintaining the structural integrity of your civil engineering works.
BS EN 12849 specifies a method for the determination of the penetration power of bituminous emulsions, through reference filler.
This test method is applicable to low-viscosity bituminous emulsions.
Who is BS EN 12849 - Determination of penetration power of bituminous emulsions for?
BS EN 12849 on bitumen and bituminous binders is useful for:
- Manufacturers of bitumen and bituminous binders
- Manufacturers and suppliers of construction materials
- Cement production companies
- Construction industry
- Concrete specialists
- Civil engineers
- Contractors
- Quality control and testing personnel
Why should you use BS EN 12849 - Determination of penetration power of bituminous emulsions?
The bitumen penetration test assesses the hardness or softness of the bitumen. The low viscosity and tiny particle size of bituminous emulsions are critical to the technique's success. In a sintered glass column apparatus, a predetermined amount of emulsion is placed upon reference fines. The amount of time it takes the emulsion to percolate through the particles is measured.
In this regard, BS EN 12849 specifies the solvents and test apparatus needed to test the penetration power of bituminous emulsions and includes test sampling, preparation and procedure.
As a result, if you are a manufacturer of bitumen and bituminous binders, BS EN 12849 -compliant test methods can be beneficial in ensuring the construction materials used play a positive role in making the pavement/road denser and more durable.
What’s changed since the last update?
BS EN 12849:2009 supersedes EN 12849:2002. BS EN 12849:2009 includes some technical changes with respect to EN 12849:2002. These include:
- New reference filler is now specified; a mixture of silica sand and silica filler is used as reference filler
