Description

Technical Field

[0001] The utility model relates to the technical field of asphalt viscosity detection, in particular to an asphalt viscosity detection device. Background Art

[0002] In industrial production and processing, in order to measure and determine the mixing temperature and paving temperature of asphalt mixture, it is necessary to measure the viscosity of asphalt. The viscosity of asphalt reflects the ability of asphalt material to resist relative flow under the action of external force. The viscosity of asphalt is usually expressed as viscosity.

[0003] By placing asphalt in a box and then stirring it while moving it up and down, and then heating it in a water bath, when the asphalt melts, it can flow into the storage box. The viscosity of the sample asphalt can then be calculated based on the time and volume of the asphalt flowing into the storage box.

[0004] Most current asphalt viscosity testing devices consist of a box and a storage box. The asphalt is heated inside the box, and the viscosity of the sample asphalt is calculated based on the time and volume of the heated asphalt flowing into the storage box. When the current testing device is heated, the asphalt in the box is heated unevenly, and residual asphalt will adhere to the inner wall of the box, resulting in deviations in the detection effect, resulting in inaccurate test results. In view of this, we propose an asphalt viscosity testing device. Utility Model Content
