Abstract：Asphalt aging oven is the main instrument for asphalt aging test in traffic and building materials industry. In order to achieve the purpose of uniform aging of asphalt samples, the aging oven can provide constant temperature environment for asphalt aging. The calibration of asphalt aging oven mainly refers to JJG (traffic) 056-2004. This paper introduces the measurement uncertainty of temperature, time and rotation rate with examples, and it has reference significance for measurement uncertainty of other similar equipment.
