Description

Technical Field

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

[0002] Asphalt penetration is an important index for evaluating the temperature sensitivity of asphalt and is also one of the main indexes for evaluating the quality of asphalt. Asphalt penetration represents the softness, consistency, and ability to resist shear failure of asphalt, and reflects the relative viscosity index of asphalt under certain conditions. The penetration grading system for road asphalt determines the climate conditions and load conditions suitable for asphalt based on the size of asphalt penetration. The main body of the penetration grading system is the familiar pull (ductility), prick (penetration), and drop (softening point), supplemented by flash point index for asphalt safety, solubility index for asphalt purity, asphalt anti-aging performance index, etc., which constitutes the asphalt penetration grading system.

[0003] When the existing asphalt penetrometer is used for asphalt penetration testing, each experimental sample needs to be tested at least 3 times. Each time a needle is used, only one data can be obtained. After each test, the needle needs to be manually cleaned and then retested, and the sample needs to be manually moved to ensure different test points each time. The operation is relatively troublesome, time-consuming and laborious, and the test efficiency is low;

[0004] During the experiment, the container for holding the asphalt sample is placed in a water bath tank. Since the water bath tank is easily offset when placed on the table, and the buoyancy will affect the stability of the container, resulting in poor measurement results. Summary of the Invention
