本欧洲标准规定了在测试温度（通常为25°C或10°C，可以使用其他温度）下确定在延展仪中的沥青粘合剂的弹性恢复方法。 它特别适用于用热塑性弹性体改性的沥青粘合剂，但也可以与仅产生小的回收率的其它沥青粘合剂一起使用。 警告 - 使用本欧洲标准可能涉及危险材料，操作和设备。本欧洲标准不旨在解决与其使用相关的所有安全问题。本欧洲标准的用户有责任建立适当的安全和健康实践，并在使用前确定法规限制的适用性

This European Standard specifies a method for the determination of the elastic recovery of bituminous binders in a ductilometer at the test temperature (typically 25 °C or 10 °C; other temperatures can be used). It is especially applicable to bituminous binders modified with thermoplastic elastomers, but can also be used with other bituminous binders which generate only small recovery. WARNING — The use of this European Standard may involve hazardous materials, operations and equipment. This European Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this European Standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
