Description

Technical Field

[0001] This utility model relates to the field of asphalt testing technology, and in particular to an auxiliary device for asphalt solubility testing. Background Technology

[0002] Solubility is one of the main performance indicators of asphalt, mainly used to characterize the chemical purity of asphalt materials and the content of effective binder components. In the asphalt solubility test, the asphalt mixture (a mixture of asphalt and asphalt solution) needs to be filtered to separate the solid and liquid components of the asphalt mixture. The solubility of asphalt is then calculated through subsequent calculations.

[0003] During the filtration process, the asphalt mixture needs to be manually guided into the crucible in droplets using a glass rod. If the guiding speed is too fast, it is easy to cause blockage. Therefore, the experimenter must operate manually throughout the process, resulting in low work efficiency.

[0004] Therefore, there is an urgent need to design an auxiliary device for asphalt solubility testing to solve the above problems. Utility Model Content

[0021] It should be noted that the valve mechanism 21 can be a rotary shut-off valve, a solenoid valve, or an electric needle valve, etc., which can be selected according to the experimental requirements.

[0022] This utility model discloses an auxiliary device for asphalt solubility testing.
