60 °C dynamic viscosity is one of the main indexes to evaluate the quality of asphalt products, and its influence on the quality of asphalt pavement is very important. 60 °C dynamic viscosity is usually measured by the asphalt vacuum decompression capillary viscometer (hereinafter referred to as the viscometer). The quality of the viscometer directly affects the test results of the asphalt dynamic viscosity. Therefore, it is urgent to study the detection method of viscometer to ensure the quality of the viscometer and the accuracy of the test results. In this paper, the calibration test method of viscometer is established, and the uncertainty evaluation is carried out, which provides a technical basis for ensuring the accuracy of viscometer.
