Ductility Test Apparatus conducts ductility tests of bituminous materials to measure the elongation of a binder specimen before failure. The ends of a molded specimen are pulled apart in a liquid-filled trough at a specified speed and temperature. Tensile strength and ductility of specimens can be measured concurrently with the addition of the Force Ductility Kits.
The ductility tester features a heating and cooling circulator for complete temperature control. It is mounted in a stainless steel water bath to precise control test temperatures and can test three standard ductility specimens simultaneously. The heating/cooling fluid circulation system uses an immersion heater and refrigerating unit to digitally regulate temperatures from 5° to 25°C ±0.5° (41° to 77°F ±0.9°). Temperature setpoints are programmed through the digital controller/display. Dual safety thermostats prevent temperature over-runs.
Operation is vibration-free with a maximum stroke of 1,500mm and a constant travel speed of 50mm per minute maintained via a direct-drive motor. Maximum force is 300 ±0.1N (67 ±0.02lbf). A traveling pointer indicates the exact position of the carriage on a fixed scale. The ductility test apparatus is housed in an enamel outer steel case, with fiberglass-insulated interior stainless steel walls. Ductility briquette molds and base plates are needed for testing specimens and are sold separately.
