Features:
-
Designed for testing the ductility of bituminous materials used in flexible pavement construction.
-
Measures the distance (cm) a bitumen briquette can be stretched before breaking, indicating ductility.
-
Briquette stretched at 50 mm/min ± 25 mm/min at 27ºC ± 0.5ºC.
-
Includes a thermostatically controlled water bath with circulating pump for uniform temperature.
-
Briquette mould halves fixed on a fixed plate and a carrier sliding over a rotating threaded shaft with clutch.
-
Two speeds available for briquette stretching: 5 cm/min and 1 cm/min, selectable via clutch.
-
Pointer moves over a stainless steel scale graduated 0–110 cm × 1 mm.
-
Motor and gears housed in cabinet above the bath.
-
Water bath is insulated aluminum with drain and thermostatic heater.
-
Control panel includes switches for motor, stirrer, heater, and indicator lamps.
