Abstract

The invention discloses a calibration device and method of a bitumen needle forcemeter. The shortcoming that in the prior art, a calibration technology of the bitumen needle forcemeter cannot calibrate simultaneous triggering of a displacement measuring device and a timing device is overcome. The calibration device comprises a sliding track arranged on a base platform, a wedge-shaped sliding block arranged on the sliding track, a range finder for carrying out ranging on sliding of the wedge-shaped sliding block on the sliding track and a timer for carrying out automatic timing of sliding of the wedge-shaped sliding block on the sliding track. The calibration device of the bitumen needle forcemeter uses an embedded multichannel integration measuring technology, simultaneous triggering of the displacement measuring device and the timing device is achieved, the fact that the bitumen needle forcemeter can reflect the consistence of bitumen really is guaranteed from the principle, and the natural shortcoming of a calibration device of an existing bitumen needle forcemeter is overcome.

Description

technical field [0001] The invention relates to the calibration technology of instruments and equipment, in particular to a calibration device and method for an asphalt penetrometer. Background technique [0002] Asphalt penetration is one of the main quality indicators of asphalt, which reflects the rheological properties of asphalt, and indicates the degree of hardness and consistency of asphalt. Penetration is measured according to the measurement method stipulated in the national standard "Asphalt Penetration Measurement Method" (GBT 4509-2010), and it is expressed by the depth that a standard needle penetrates directly into the asphalt sample under a certain load, temperature, and time. The unit is 0.1 millimeter (mm). [0003] Asphalt Penetrometer is the main instrument for measuring needle penetration. The Asphalt Penetration Tester is suitable for measuring the penetration of road petroleum asphalt, polymer modified asphalt, and residues after distillation of liqui...
