This European Standard provides a framework for the specification of oxidised bitumen used mainly in roofing, waterproofing and adhesives. Within Europe several types of oxidised bitumens are used and, dependent on climatic conditions, type of building construction and traditional practices, different grades may be used for the same purpose. The framework given in this Standard provides a basis for quality agreements to be established between supplier and client. The oxidised bitumen products are graded by a combination of the values of ring and ball softening point and penetration at 25 °C, expressed as multiples of 5.
