What is BS EN 15322 - Framework for specifying cut-back and fluxed bituminous binders about?
BS EN 15322 is a European standard on bitumen and bituminous binders. The main objective of BS EN 15322 is to ensure bitumen and bituminous binders play a positive role in maintaining the structural integrity of your civil engineering works.
BS EN 15322 provides a framework for specifying cut-back and fluxed bituminous binders which are suitable for use in the construction and maintenance of roads, airfields and other paved areas.
BS EN 15322 applies to un-modified and polymer modified bituminous cut-back and fluxed materials.
Who is BS EN 15322 - Framework for specifying cut-back and fluxed bituminous binders for?
BS EN 15322 on framework for specifying cut-back and fluxed bituminous binders is useful for:
- Manufacturers of bituminous materials and other petroleum products
- Manufacturers of binders used as sealing materials
- Manufacturers and suppliers of construction materials
- Manufacturers of cut-back and fluxed bituminous binders
- Quality control and testing personnel
- Construction companies
- Civil engineers
- Contractors
Why should you use BS EN 15322 - Framework for specifying cut-back and fluxed bituminous binders?
Cutback bitumen is a petroleum product produced by diluting bitumen in petroleum hydrocarbon and vegetal flux is a type of bio-flux derived exclusively from plant based (vegetal) products. Therefore, bitumen, when used as a binder in asphalt, is used in the construction of roads, pavements, airfields and roofing. The aim of the cut-back and fluxed bituminous binders is to decrease the viscosity and increase the penetration of bitumen on the asphalt surface.
In this regard, BS EN 15322 provides the best industry recommendations on product requirements and characteristics and includes test methods for testing cut-back and fluxed bituminous binders along with its marking and labelling.
BS EN 15322 also covers guidance on Assessment and Verification of the Constancy of Performance (AVCP) that ensures your products conform with the requirements.
Thus, if you are a manufacturer of bituminous binders, complying with BS EN 15322 can help demonstrate the quality and performance of the asphalt that enhances the durability and service life of roads and pavements.
What’s changed since the last update?
BS EN 15322:2013 supersedes EN 15322:2009 and EN 14733:2005+A1:2010. BS EN 15322:2013 includes some technical changes with respect to EN 15322:2009 and EN 14733:2005+A1:2010. These include:
- Revision of viscosity performance classes in Table 3
- Rewriting of Clause 6 (Assessment and Verification of the Constancy of Performance - AVCP) and Annex ZA in accordance with the requirements of Regulation (EU) 305/2011 (Construction Products Regulation-CPR)
- Incorporation of the clauses on AVCP previously covered by EN 14733:2005+A1:2010
