沥青性能的评价,从针入度分级体系、粘度分级体系到PG分级体系,沥青粘度的测量显的越来越重要。但测量沥青的粘度不像测量针入度、软化点、延度等参数那样容易测量,粘度指标受各种影响因素较多,测量方法多样。按测量结果分为运动粘度、动力粘度(绝对粘度)、条件粘度等,按测量方法分一是粘度杯法,如沥青标准粘度计、恩格拉粘度计、赛波特重质油粘度计等;二是毛细管法,如毛细管法测量运动粘度、真空减压毛细管法测量动力粘度;三是旋转法测量粘度,即布洛克菲尔德(Brookfield)粘度计。其它测量粘度的方法如落体法、振动法、平板法等,目前还没有在沥青粘度 Asphalt performance evaluation, from the penetration degree grading system, viscosity grading system to PG grading system, the measurement of asphalt viscosity is obviously more and more important. However, the measurement of asphalt viscosity unlike the measurement of penetration, softening point, ductility and other parameters as easy to measure, viscosity index by a variety of influencing factors, measurement methods and diverse. According to the measurement results are divided into kinematic viscosity, dynamic viscosity (absolute viscosity), the conditions of viscosity, according to the measurement method is divided into one cup viscosity method, such as asphalt standard viscometer, ENGELA viscometer, 赛 Porter heavy oil viscometer; Second, the capillary method, such as the capillary method of measuring the kinematic viscosity, vacuum depressurization capillary method to measure the dynamic viscosity; third is the rotation method of measuring viscosity, that is, Brookfield (Brookfield) viscometer. Other methods of measuring viscosity such as falling body method, vibration method, plate method, etc., there is no asphalt viscosity
