1. Sample preparation
According to the requirements of JTG3410-2025 standard, the residue of road petroleum asphalt, modified asphalt, or liquid petroleum asphalt/emulsified asphalt after evaporation should be heated to a flowing state and slowly poured into a metal test dish (select 70 × 45mm or 55 × 35mm specifications according to the sample type), so that the sample is 5mm above the edge of the dish mouth. After cooling at room temperature for 1.5 hours, it should be transferred to the tripod of a flat bottomed insulation dish, and a medium (such as water or glycerin) with a temperature that meets the test requirements should be added to ensure that the medium is immersed in the sample and the liquid level is not less than 10mm from the dish mouth. The constant temperature should not be less than 1.5 hours.
2. Equipment debugging
Connect the device power supply (AC220V ± 10%, 50Hz), turn on the power switch, and confirm that the device self-test is normal through the four digit LCD display screen; According to the test standards, set the test time (5s/15s/30s/60s), adjust the horizontal position of the work platform (within the range of 0-20mm), manually move the penetration needle rod, so that the standard needle tip is about 1-2mm away from the surface of the sample, and ensure that the needle tip is vertically aligned with the center area of the sample.
3. Formal experiment
Click the "Start" button on the device, and the standard needle will automatically penetrate the sample under a total weight of 100 ± 0.05g. After reaching the set time, the device will automatically record the penetration displacement (with an accuracy of 0.01mm); The same sample shall be tested continuously for 3 times according to the above steps, with a minimum distance of 10mm between each test point and a minimum distance of 15mm from the edge of the test dish to avoid edge effects on the data.
4. Post experimental processing
After completing three experiments, the equipment automatically calculates and displays the average value; Turn off the device power, remove the test dish, clean the residual asphalt on the standard needle tip (to avoid affecting the next test), recover the medium in the insulated dish, and tidy up the test bench.
1. Basic information of the report
Includes test date, test personnel, equipment number, sample information (sample name, type, manufacturer, batch), test basis standards (JTG3410-2025, T0604-2011), test medium type, and constant temperature.
2. Raw data recording
Record the penetration time (set value) and single penetration displacement (accurate to 0.01mm) of 3 tests
3. Result calculation and judgment
Based on the average of three tests automatically calculated by the equipment (accurate to 0.1mm), compare the penetration technical requirements of the corresponding asphalt type in JTG3410-2025 standard to determine whether the penetration of the sample meets the standard requirements; If the deviation between the single test data and the average value exceeds the standard allowable range (usually not greater than ± 5%), resampling is required for the test.
4. Remarks and explanations
Record any abnormal situations during the test process (such as equipment prompts, medium temperature fluctuations, etc.), and indicate whether they have an impact on the test results; If conducting sensor calibration, an additional calibration record number is required to ensure the traceability of test data.
