DIN EN 13587:2010-10

The document EN 13587:2009 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). With respect to DIN EN 13587:2004-03, the following changes have been made: a) 5.1.4 "Optical extensometer" has been added; b) in clause 6 an alternative method for the preparation of samples has been added; c) note in clause 7 has been added to the normative text; d) the standard has been editorially revised. This European Standard specifies a method for determining the tensile properties of bituminous binders, in particular those of a polymer modified bitumen, by means of a tensile test. A specimen, held by its ends between two jaws, is extended in a chamber, regulated at a specified test temperature, at constant speed until fracture or a given percent elongation is achieved. In general, stress and percent elongation are noted at the flowing threshold, at breaking and at a percent elongation of 400 %.
