Ductility Testing Machine is defined as the distance in cms to which a standard briquette of bitumen can be stretched before the thread breaks. The briquette is stretched at a rate of 50 mm /min. /2.5 mm per minute at a temperature of 27ºC /0.5ºC.The apparatus consists of the water bath with a thermostatic heater and a circulating pump to maintain uniform water temperature One half of the briquette molds is fixed on a fixed plate in the water bath, the other half of the briquette mold is fixed to a carrier which slides over a rotating the threaded shaft with a clutch. The motor and gears to rotate the shaft are housed in a cabinet fixed above the other end of the bath. A pointer fixed to the carrier moves over a scale graduated from 0-110 cm x 1 mm fixed on the bath with 0 (Zero) of the scale towards the fixed plates side. The rotating shaft has 2 speeds of travel for the bracket, 5 cm/min and 1 cm/min. selected by a clutch. Water bath inside is aluminum/ S. steel, it is an insulated water bath Water bath is provided with a drain. A heater with thermostatic control is fixed inside the water bath. Control switches for motor pump heater and indicator lamps are fixed at a convenient place on the water bath. Complete with three briquette molds and one base plate, steel all made of brass operates on 230V A.C. supply single phase.

1. Microprocessor based circuitry assures precise, reliable temperature control within specified tolerances throughout the operating range of the bath i.e. 10 °C to ambient temperature.
2. Dual digital displays show set and actual bath temperature
3. Simple push button controls and digital display permit easy setting and monitoring of bath temperature.
4. Bath accommodates 04 Nos glass capillary reversion viscometers of various types at a time
5. Viewing the viscometers is made easy by glare‑free fluorescent illumination.
6. Temperature control uniformity is assured by means of motorized stirrer, which provides complete circulation without turbulence.
7. Frost free glass window for low temperature bath
8. Control panel is mounted on a side of the bath
9. Complete exterior body is finished with attractive powder coated paint
