Study on Calibration Method of Wax Content Tester of Asphalt
Asphalt wax content is a key index affecting the performance of road asphalt,which is widely used in road construction industry.At present,there is no unified national technical specification for the instrument.Therefore,in order to meet the measurement needs and improve the accuracy of detection,this paper analyzes and discusses the structure composition,measurement standards and supporting equipment,calibration methods and data processing,and evaluates the uncertainty of temperature indication error and temperature fluctuation.The results show that the method is feasible and can provide reference for the calibration of the measuring instrument.
