This testing machine is applicable for measuring the ductility to the material such as various specifications and models of bitumen and liquid bitumen, the residue after the liquid bitumen distillation, bitumen emulsion residue etc. It has the advantages of step-less speed variation, large power cycling, low noise, long servicelife and so on.

It can automatically calculate and display the ductility average value to three samples. It is widely used in the production, road constructionscientific research departments, It is more fit for the rectified bitumen experiment.
