摘要
考察了沥青的针入度、软化点、60℃动力黏度、延度、基质沥青蜡含量、薄膜烘箱试验、储存稳定性的检测方法。重点考察了沥青的加热方式、加热次数、水浴温度、加热介质、黏度管选型、黏度管系数、基质沥青蜡含量试验中溶剂的添加顺序、不同烘箱仪器等因素对检测指标的影响。提出了正确的操作步骤、注意事项、溶剂的选择、选择正确的仪器等内容。
In this paper, the test methods of asphalt penetration, softening point, 60 ℃ dynamic viscosi-ty, ductility, wax content of matrix asphalt, thin film oven test and storage stability were examined, focused on the factors that affected detection indexes： asphalt heating mode, heating time, water bath temperature, heating medium, choice of viscosity tube, viscosity coefficient, the adding order of solvent in matrix asphalt wax content test and different drying oven. The correct operation steps , matters needing attention, solvent se-lection, right instrument, ete were put forward.
