Common Faults and Solutions for Asphalt Extensometers
If the instrument exhibits issues such as inaccurate temperature control or temperature fluctuations, please follow the steps below to correct the temperature setting.
Check whether the circulating water pump is operating properly and whether the pump’s outlet pipe is bent or twisted. Inadequate water circulation can lead to temperature fluctuations.

Precautions for Using the Asphalt Penetration Tester
The penetration tester for asphalt is primarily used to determine the penetration of viscous petroleum asphalt, viscous shale asphalt, liquid petroleum asphalt, and the residue remaining after distillation or emulsification of asphalt materials.

Adjustment and Operating Procedures and Precautions for the Asphalt Penetration Tester
The penetration tester for asphalt is primarily used to determine the penetration of viscous petroleum asphalt, viscous shale asphalt, liquid petroleum asphalt, and the residue remaining after distillation or emulsification of asphalt materials. The penetration of asphalt is defined as the depth to which a standard needle of specified weight penetrates vertically into the sample under prescribed time and temperature conditions.

Analysis of the Advantages and Structural Features of the Rotary Compactor
Using this device, the cooperating instrument’s own compaction view-setting dial allows for quick adjustment of the compaction view within a range of 0° to 2°. The entire process of resetting the compaction view takes only 10 minutes, whereas adjusting the compaction view on imported instruments involves a much heavier workload and typically takes more than 2 hours.

Instructions for Use and Maintenance Precautions for the Asphalt Extensometer
In the test, if asphalt fibers are found floating on the water surface or sinking to the bottom of the tank, salt should be added to the water to adjust its density to match that of the sample, and the test should be repeated. (If the asphalt density is known, salt can be added in advance.)
