JQ-020Fully automatic asphalt mixture bending creep tester

Product Introduction:

JQ-020Fully automatic asphalt mixture bending creep testerFully comply with the requirements of JTG E20-2011 "Test Code for Asphalt and Asphalt Mixtures in Highway Engineering".used forMeasure the strain rate of bending creep of hot mix asphalt mixture specimens at specified temperature and loading stress level to evaluate the deformation performance of asphalt mixture

JQ-020fully automaticProduct performance:

The displacement and time relationship curve displayed on the LCD screen.

And automatically judge the test results.

Automatically control the entire testing process (including loading, protection, testing, judgment, and unloading)

Set up computer interface to print curves and results through the computer.

JQ-020fully automaticTechnical parameters:

1. Maximum load and accuracy: 30kg ± 5g

2. Displacement measurement range and accuracy: 0-20mm ± 0.01mm.

3. Temperature control range and accuracy: 60 ℃～ -20 ℃± 0.1 ℃.

4. Equipped with a water circulation system to ensure temperature balance.

5. Time measurement range and accuracy: 0-60min ± 1S.

6. It has segmented sampling function. Sampling rate: Within 10 seconds after starting loading, the sampling rate shall not be less than 100Hz; Within the next 5 minutes, it shall not be less than 1HZ; Then, maintain a frequency of no less than 0.2Hz until the end of the experiment.

7. LCD screen displays displacement and time relationship curve. And automatically judge the test results.

8. Set up computer interface to print curves and results through the computer.

9. Automatically control the entire testing process (including loading, protection, testing, judgment, and unloading)

10. Interface settings: 220V main power supply and computer interface

11. The vertical loading method is adopted to avoid the disadvantage of unstable load caused by unreasonable structure, and the performance is reliable.
