What is BS EN 12592 – Determination of the solubility of bituminous binders about?
BS EN 12592 is a European standard that discusses the solubility of bitumen and bituminous binders.
The main objective of the BS EN 12592 series is to ensure bitumen and bituminous binders play a positive role in maintaining the structural integrity of your civil engineering works.
BS EN 12592 specifies a method for determining the degree of solubility of bituminous binders having little or no mineral matter other than recovered bituminous binders from asphalt mixes, in a specific solvent. Toluene is used as the solvent for reference tests.
Note: Bituminous binders will have varying solubility in different solvents.
Who is BS EN 12592 - Determination of the solubility of bituminous binders for?
BS EN 12592 on bitumen and bituminous binders is useful for:
- Manufacturers of bitumen and bituminous binders
- Manufacturers and suppliers of construction materials
- Quality control and testing personnel
- Construction companies
- Civil engineers
- Contractors
Why should you use BS EN 12592 - Determination of the solubility of bituminous binders?
A solubility test on bitumen can be used to verify its purity and stability. To have high quality road construction it is imperative that high quality bitumen without impurities must be used.
In this regard, BS EN 12592 specifies the solvents and test apparatus needed to test the solubility of bituminous binders. BS EN 12592 guides you through the standard test technique for checking aggregate boundaries and creating a distinct cohesiveness and stability to the bituminous mix.
By evaluating solubility in accordance with BS EN 12592, you can eventually estimate and measure the percentage of soluble bitumen content in an organic solvent, ensuring that your pavement/road is denser and more durable.
What’s changed since the last update?
BS EN 12592:2014 supersedes EN 12592:2007. BS EN 12592:2014 includes some technical changes with respect to EN 12592:2007. These include:
- Changed/added wording of the Warning in the Scope
- The function of the powdered glass (subclause 6.1.2) as filter aid has been highlighted in the standard
- Preparation of the test sample according to EN 12594 in subclause 8.3 has been added
