A Brief Analysis of the Composition, Installation, and Usage of the Asphalt Extensometer
The asphalt ductility tester places an asphalt specimen of a specific shape and size into a water medium maintained at a constant temperature, then stretches it at a constant speed. The length of the specimen measured when it breaks is referred to as the asphalt ductility, with the unit being centimeters.

How should the asphalt ductility tester be operated correctly?
The asphalt ductility tester is suitable for measuring the ductility of asphalt materials of various specifications and models, as well as the residual materials left after distilling liquid asphalt and the evaporative residues from asphalt emulsions. It can automatically calculate and display the average ductility value of three specimens, with digital temperature display.

Composition and Application of the Asphalt Extensibility Tester
The mechanical stretching device is driven by a low-speed motor and, via transmission gears and racks in the gearbox, moves from one end to the other. The transmission system is also equipped with a variable-speed mechanism, enabling two different stretching speeds to be achieved.
