Rotating bottle abrasion tester

The instrument is designed and manufactured in accordance with the technical and functional requirements of the rotating bottle abrasion instrument in the T 0758-2011 "Dilute slurry mixture compatibility grade test" of the industry standard JTG E20-2011 "Test Rules for Highway Engineering Asphalt and Asphalt Mixture". It is applicable to complete the rotating abrasion treatment of the sample according to the standard test method, and then calculate and determine the compatibility between the aggregate with a specific grade and the modified emulsified asphalt.

Main technical features

1. It is floor-standing, box-type structure, reasonable structure and easy to use.

2. With orthogonal double-bracket structure mode, 8 samples can be tested at the same time at a time, and the work efficiency is high.

3. The proximity switch is used as a counting device for the number of rotations, which is accurate and reliable.

4. The structure of the whole machine is stable and can meet the requirements of simultaneous rotation and abrasion test of multiple samples.

5. It is designed with automatic memory function after power failure, the number of rotations can be accumulated, and can also be counted from zero after resetting.

6. The specifications and dimensions of the test equipment meet the requirements of the T 0758 standard.
