Carefully read T0623 "Asphalt Dynamic Viscosity Test (Vacuum Decompression Capillary Method)" in the Transportation Industry Standard of the People's Republic of China JTJ052 "Testing Methods for Asphalt and Asphalt Mixtures of Highway Engineering" or the People's Republic of China Petroleum Industry Standard SH / 0557 Petroleum Bitumen Viscosity Method (Vacuum Capillary Method) "to understａnd and be familiar with the test methods, test procedures and test requirements described in the standard.
3. According to the requirements specified in the standard, prepare various test instruments and materials for testing.
4. Check the working status of the instrument to make it comply with the working environment and conditions specified in the instructions.
5. Check the case of the instrument, it must be in a good grounding state.
★ Instrument operation
1. Add a sufficient amount of water to the glass bathtub (the water surface is about 30mm away from the cover). When there is a light on the power switch, the circuit is on.
2. Press the "Set" key on the panel of the temperature controller, turn the setting knob to display 60.00 ℃ on the temperature controller, and then press the "Set" key again, the temperature control system will start the constant temperature control and make the water bath The temperature is constant at 60.00 ℃ ± 0.01 ℃.
3. Put the capillary tube and the sample in an oven (135 ° C ± 5 ° C) for 30 minutes, then inject the asphalt sample from the filling tube A into the capillary viscometer. The sample should not stick to the tube wall, and the test The sample liquid level is within ± 2mm at the loading line, and then return the capillary viscometer with the sample back to the oven (135 ℃ ± 5 ℃), and keep it for 10min ± 2min to allow the bubbles generated in the tube to escape. Out.
4. Take the capillary viscometer out of the oven, and cool it at room temperature for 2 minutes, then install it in a water bath that maintains the test temperature. Its position should be at least 20mm below the liquid level of the water bath. Make sure the vacuum valve is closed and the vacuum tube is connected To the end of the capillary.
