Description

Technical Field

[0001] The utility model relates to the technical field of asphalt penetration testing, in particular to a high-precision asphalt penetration testing device. Background Art

[0002] Asphalt penetration is one of the key quality indicators of asphalt. It indicates the asphalt's hardness, consistency, and resistance to shear failure, reflecting the relative viscosity of asphalt under certain conditions. At 25°C and under a 100-gram load for 5 seconds, the penetration depth of a standard cone vertically into an asphalt specimen is measured in tenths of a millimeter. An asphalt penetration tester is an instrument used to measure the hardness and consistency of asphalt. It determines asphalt penetration by measuring the depth to which a standard needle vertically penetrates the asphalt specimen under a specified time and temperature.

[0003] However, the existing asphalt penetration tester requires fine-tuning of the needle tip when in use. However, since the position of the asphalt penetration tester is fixed and the observation effect of the needle tip is different at different positions, the accuracy of the needle tip position adjustment cannot be guaranteed when different people fine-tune the needle tip, so multiple observations and repeated adjustments are required, which is more troublesome to operate.
