适用范围：This European standard describes the determination of Zero Shear Viscosity (ZSV), ηo, for bitumens and bituminous binders, preferably using test temperature domains in which 100 Pa.s < ηo < 50 000 Pa.s. The preferred test temperature is 60 °C but other temperatures for example, 45 °C or 50 °C could be used. Under these conditions, ZSV (also referred to as the first Newtonian viscosity or absolute viscosity) is a suitable indicator to evaluate the partial contribution of the bituminous binder (including Polymer Modified Binders) to the rutting resistance of asphalt pavement layers. This European standard describes the determination of ZSV using a Shear Stress Rheometer (SSR) in creep mode. This method is applicable to unaged, aged and recovered bituminous binders including Polymer Modified Binders (PMBs). WARNING — Use of this European standard can 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. Since this European standard involves handling apparatus and binders at high temperatures, always wear protective gloves and eye glasses when handling hot binder, and avoid contact with any exposed skin.
