Full Description This European Standard specifies a method for the determination of the elastic recovery of bituminous binders in a ductilometer at a given temperature. It is especially applicable to bituminous binders modified with thermoplastic elastomers, but may also be used with other bituminous binders which generate only small recovery. It also provides a suitable means to determine the heat resistance of thermoplastic elastomers in modified binders under specified thermal stress according to EN 1427.
