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.
Insulated stainless steel water bath with a heating system located over the entire base surface and a stainless steel 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.
Double-screew rods and mobile carriage enable test speeds from 3 to 200 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, manual intervention is not required.
Load and elongation measurement
Automatic measurement of the elongation by an encoder. Includes a system for measuring forces up to 2000 N (4 x 500 N) with load cells (see accessories).
By PC (not included)
This model is proposed without a chiller for use with a suitable cooling system that could be available in the laboratory. It is important, however, that this unit is capable of delivering a flow rate of 6 litres/min, 1 bar, at the minimum temperature of 2°C.
Essential for better temperature control of the bath.
