Bitumen Ductility Tester

This instrument is designed and made as per  ASTM D113 Standard Test Method for Ductility of Bituminous Materials. It is suitable to determine the distance to which it will elongate before breaking when two ends of a briquette specimen of the material are pulled apart at a specified speed and at a specified temperature, which is named as the asphalt ductility, and also it can measure the ductility of the coal tar pitch. The maximum measurement distance is less than 1500mm, and it can do bitumen ductility, force and bitumen elastic recovery capacity.

I.     Main technical characteristics

1. Industrial touch screen, advanced technology, high-end products, excellent performance. Full touch screen operation, convenient and fast.

2.32-bit ARM microcontroller control, automatically control the water bath’s temperature, automatically collect, deal with dragging and force data, full touch screen operation, convenient and fast.

3. The new stretch drive design adopts the combination of imported screw rod and guide rail. The stretch process is stable and synchronous, no shaking, with uniform speed and accurate display of ductility and tension.

4. Using high-power compressor refrigeration, shield type cold and heat balance pressurization cycle system, refrigeration speed is fast, bath temperature is uniform.

5. Data storage, easy to query.

6. The average ductility value, the maximum tensile force and the elongation deformation value under the maximum tensile force are automatically calculated and displayed.

7. One machine with multiple functions and one asphalt ductility tester can test asphalt ductility, asphalt force ductility and asphalt elastic recovery ability.
