Asphalt Cohesive Tester

This instrument is used to determine the time required for complete solidification of emulsified asphalt slurry seal mixtures, in order to determine the early opening to traffic time after the construction of emulsified asphalt slurry seal mixtures.

1. Pneumatic bidirectional cylinder
2. A rubber pad with a hardness of 60, measuring 28.6*6.4mm
3. Air pressure regulator with adjustable exhaust valve to maintain constant air pressure
4. Bidirectional control valve for raising or lowering the rubber base
5. Air pressure gauge (0-1.0Mpa)
6. Pressure port for connecting a bicycle pump or air compressor to pressurize the cylinder
7. Torque wrench (0-600N·CＭ)
8. Ring-shaped molds (6*60mm, 10*60mm)

The report should include the following information:

1. Emulsifying agent and asphalt type used for emulsified asphalt preparation, dosage of emulsifying agent, asphalt content.
2. Types and gradation of aggregates.
3. Solidification time of emulsified asphalt slurry seal mixtures.

Precautions:

1. If the instrument is not used for a long time, move the piston rod up and down every two weeks.
2. If the piston is too tight, lubricating oil should be added. The torque measuring plate should also be rotated a few times every month.
