Asphalt standard viscometer instruments and materials:
I. Road asphalt standard viscometer: It consists of the following parts:
★ Water trough: ring trough, inner diameter 160mm, depth 100mm, there is a round well in the middle, the distance between the well wall and the water trough is not less than 55mm. The ring tank stores liquid (water or oil) for heat preservation, and A water pipes are arranged on the upper and lower sides. The bottom of the water tank is about 200mm from the test bench. Water tank temperature control precision ± 0.2 ℃.
★ Sample tube: The tube body is brass and the bottom plate with flow holes is made of phosphor bronze. There are four orifices d in the sample tube: 3mm ± 0.025mm, 4mm ± 0.025mm, 5mm ± 0.025mm, and 10mm ± 0.025.

五、使用方法和注意事項：
★ 本試驗儀應水平放置于工作臺面上，室溫0~30℃，相對濕度不超過80%，無震動，無腐蝕性氣體，且有良好的接地保護。
★ 使用前，先在恒溫水浴內注入A的自來水，水位高度約為離上平面 15mm，用隨機軟管把兩臺儀器連接成一體。
★ 把兩臺儀器都插上電源（220V，50Hz），先啟動恒溫水浴部分的電源開關，按照溫度控制器的使用說明書調節溫度到所需要的值，啟動加熱和攪拌開關，經過一段時間后， 能達到所需的溫度值。
★ 設置好恒溫水浴部分后，然后開啟真空度控制部分的電源開關。當電源開關打開后，真空泵直接開始工作，使用者可根據真空表說明書設定真空度（一般情況下，出廠時已經為用戶進行了設置，不需重新設置）。根據表上的數值，慢慢地用調壓閥調節真空度，這個過程須經過幾次反復。（此時必須關閉連接毛細管的閥門）。
★ 試驗過程中，打開照明開關，以便清晰觀察整個試驗過程。
Asphalt standard viscometer use method and precautions:
★ The tester should be placed horizontally on the work surface, room temperature 0 ~ 30 ℃, relative humidity not exceeding 80%, no vibration, no corrosive gas, and good grounding protection.
★ Before use, inject the tap water of A in the constant temperature water bath, the water level is about 15mm from the upper plane, and connect the two instruments into one with a random hose.
★ Plug both instruments into the power supply (220V, 50Hz), first turn on the power switch of the constant temperature water bath part, adjust the temperature to the required value according to the instruction manual of the temperature controller, and start the heating and stirring switch. Able to reach the required temperature value.
★ After setting the constant temperature water bath part, then turn on the power switch of the vacuum degree control part. When the power switch is turned on, the vacuum pump starts to work directly, and the user can set the vacuum degree according to the manual of the vacuum gauge. According to the value on the table, slowly adjust the vacuum with the pressure regulating valve. This process must be repeated several times. (The valve connecting the capillary must be closed at this time).
★ During the test, turn on the light switch to clearly observe the entire test process.
