　　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.According to the needs of the experiment,choose the aperture of the sample optical flow hole.

　　★Ball plug:used to block the flow hole,there is a mark on the rod.The diameter of the ball plug with a diameter of 12.7mm±0.05mm is 92mm±0.25mm,which indicates the height of the sample in the 10mm sample tube.The diameter of the ball plug with a diameter of 6.35mm±0.05mm is 90.3mm±0.25mm,which indicates The height of other samples in the sample tube.
