Bitumen and bituminous binders - Characterization of perceptible properties; German version EN 1425:2012

Title (German)

Bitumen und bitumenhaltige Bindemittel - Feststellung der äußeren Beschaffenheit; Deutsche Fassung EN 1425:2012

Overview

The properties of bituminous binders depend on a number of factors, such as type (pure bitumen, bitumen emulsion, cutback or fluxed bitumen), grade and temperature. The physical properties are determined by the appropriate test methods. The perceptible properties, such as appearance and odour, are determined by sensorial observation. It is, for instance, quite simple to distinguish by smell flux oil from a bituminous binder. Often other properties, such as homogeneity, cannot be determined by visual inspection alone due to the high consistency (viscosity) of the bituminous binder. However, in the case of bituminous binders such as bitumen emulsions, cutback or fluxed bitumen, the presence of lumps, agglomerates or sediments can be observed. This document specifies a method for the determination of the perceptible properties of bituminous binders at ambient temperature prior to testing for other properties. The use of this standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. The document (EN 1425:2012) has been prepared by Technical Committee CEN/TC 336 "Bituminous binders", the secretariat of which is held by AFNOR (France). The responsible German committee is Joint Committee NA 062-03-32 GA "Bitumen; Prüfverfahren und Anforderungen für die Bindemittel" ("Bitumen; test methods and specifications of binders") of the Materials Testing Standards Committee (NMP) and of the Building and Civil Engineering Standards Committee (NABau). The following modifications have been made with respect to DIN EN 1425:2006-04: a) contents have been editorially revised; b) normative references have been updated.
