Ductility Testing Machines for Bitumen Testing

Ductility Testing Machines are designed to determine the ductility of asphalt and semi-solid bitumen by measuring the elongation distance of a specimen before rupture. During the test, the specimen is pulled at a controlled speed while immersed in a constant-temperature water bath maintained at 25 ± 0.5°C.

The machine operates automatically at a pulling speed of 50 mm/min with a maximum stroke length of 1500 mm, delivering accurate, reliable, and repeatable test results in accordance with international standards.
