The ductility test is performed for determining the ductility of bituminous materials by measuring the elongation before breaking when two ends of briquette specimens are pulled apart at a specified speed and temperature.

Carriage displacement

Double-screw rods and mobile carriage enable test speeds from 5 to 100 mm/min. The system also permits the fast return of the carriage at the end of the test (500 mm/min) to reduce dead time and increase productivity. The carriage return is automatic so manual intervention is not required.

Water bath

Insulated stainless steel water bath with a heating system located over the entire base surface and a cooling coil (for connection to water mains or chiller) distributed over the three side walls assuring temperature uniformity without water turbulence inside the bath. All parts in contact with water are made of stainless steel.

Temperature control

A closed-loop PID system assures constant temperature

Plate-type base heaters give better temperature uniformity

Machine control and elongation measurement

Control panel with digital display to set the testing speed: 5 to 100 mm/min, with the carriage return function. Elongation measurement by encoder. The machine can be completed with a transparent cover.

Main Features:

4 tension line (briquette capacity) x 1500 mm 

Easy and free access to the large testing space

Adjustable speed range from 5 to 100 mm/min

High carriage return speed of 500 mm/min for greater productivity

Closed-loop PID temperature control system

Stainless steel insulated water bath 

Elongation measurement by encoder read on display

Exclusive in-built thermoregulation system compensating the exchange of heat and cooling, resulting in a very strict temperature control, optimized by the connection to chiller.
