scope of application:

This instrument is designed to measure the elongation of various specifications and types of asphalt, including the residue after distillation and the residue from the evaporation of asphalt emulsions. It is widely used in production, road construction, and research, particularly for testing modified asphalt. The instrument complies with the GB/T 4508 'Test Method for Elongation of Petroleum Asphalt' and JTG E20-2011 T 0605-2011 'Elongation Test for Asphalt'.

Performance features:

1. Use high-definition camera to observe the whole process of tensile test, record and store the fracture of specimens automatically. (No manual operation after starting)

2. The split design is adopted, and the experimental tank is connected to the temperature control equipment. There is no vibration in the tank during the experiment.

3. The water used in the peristaltic pump test has no ripple and visible water flow, and the water temperature fluctuation in the test process is guaranteed within 0.1℃ to meet the test requirements.

4. The driving device adopts double linear guide bridge connection, which ensures that the swinging of the specimen is less than 0.2 mm during the experiment and ensures the accuracy of the test results.
