Design and Testing of Bituminous Mixtures
The Ductility Testing Machine is used to determine the ductility of bituminous materials in a briquette mould by measuring the breaking elongation at a constant speed of 50 mm/min. It is designed for testing 3 specimens simultaneously. The Internal tank is made of stainless steel. The bath is fitted with an immersion heater in order to obtain (in normal conditions), the 25°C test temperature.
The Ductility Testing Machine comprises of speed control and water circulator to maintain the homogenous water temperature.
Elongation measurement through the motor encoder.
3 simultaneous load measurements with 18-bit resolution.
Speed control with servo AC motor between 0.01 to 100 mm/min.
Ethernet connection for computer interface.
Has 3 load cells with an accuracy of ±0.1N, with a maximum capacity of 300 N.
Failure conditions can be downloaded to the unit.
Complies with EN 13398, ASTM D113, ASTM D6084, AA SHTO T51, EN 13589, EN 13703, AASHTO T300.
