Study on Calibration Method of Compacted Asphalt Mixture Density Tester
In order to meet the requirement of quantity value traceability of compact asphalt mixture density tester,this paper proposes calibration schemes for temperature deviation,temperature uniformity,temperature fluctuation,weighing indication error and weighing repeatability by analyzing the structure of the tester according to relevant measurement technical specifications,thus determining the measurement standards and calibration methods required for calibration.The uncertainty of calibration results is evaluated.
