Ductility Testing Machine
The ductility of bitumen is expressed as the distance in centimeters to which a standard briquette can be elongated before the thread formed breaks under specified conditions. A molten bitumen sample is pored into a standard mould, allowed to cool to room temperature and then placed in a water bath so that the briquette can be brought to test temperature before mounting in the testing machine.
Designed to test three specimens simultaneously, the machine consists of a carriage moving over a lead screw. An electric motor driven reduction gear unit ensures smooth constant speed and continuous operation. The entire assembly is mounted with water bath completely encased in metal bound hardwood. It is equipped with an electric pump circulator and heater. The temperature is controlled by a digital temperature controller. Two rates of travel – 5cm/minimum and 1cm/minimum – are provided. The machine is supplied complete with four ductility molds, each with a base plate.
