摘　　要：沥青标准粘度计是测定液体石油沥青、煤沥青和乳化沥青等材料流动状态时粘度的仪器。由于沥青粘度的准确性直接关系着沥青混凝土路面质量的好坏,因此,改进其校准方法对公路工程建设具有重要意义。本文通过对其结构及工作原理的分析,根据相关计量技术规范,确定校准所需的测量标准、校准方法,并对校准结果进行测量不确定度评定,从而确保量值准确可靠。Asphalt standard viscometer is an instrument to measure the viscoity of liquid petroleum asphalt,coal asphalt and emulsified asphalt in the flow sate.ee he acurary of at scosty is diretly taed o te quality of asphalt concrete pavement,it is of great significance to improve its calibration method for highway con-struction.Based on the analysis of its structure and working principle,this paper determines the measurement stand-ards and calibration methods required for calibration accorling to the relevant metrological technical specifications,and cvaluates the mcasurement uncertainty of the calibration results,so as to ensure the accuray and reliability of the measurement value.
