We offer Ductility Testing Machine to the customers. The Ductility Testing Machine meets the requirement of IS 1208-1958 and is used in determining the ductility of esphaltic bitumen, fluxed native, asphalt out back bitumen one blown type bitumen. The ductility of bituminous material is measured by distance in contiretras to which it will elongate before when two ends of standard briquette specimen of material are pulled apart, at a specified speed and a specified temperature. Comprises of : One wooden frameOne gear and motor box with speed selectorTwo bracketLead screw one scale fixed on the edge of motorOne scaleOne thermostat One immersion element Description : The Ductility Testing Machine consists of a Water Bath surrounded by a raised wooden frame and two brackets with pins to hold clips of three ductility moulds. Provision has been made to three briquettes at a time. One bracket is fixed to the Water Bath. The second bracket moves on a lead screw rotated by a chain drive, the speed of which is regulated by a reduction gear system coupled to a fraction horse power motor. Two rates of travel are incorporated. These are 5 cm/minute and 1 cm/minute. An index pointer fixed to the movable bracket moves over a scale marked in centimeters fixed on the edge of the Water Bath and indicates distance traveled. A clutch arrangements is provided by which the movement of the movable bracket can be arrested or restored without switching off the motor. When the clutch handle is pulled to engage position it starts the rotation of the lead screw and the clutch is pushed back to disengaged position is arrests the motion. The Water Bath is provided with thermostatically controlled heater. An inbuilt pump is fitted to circulate water in the bath for keeping the temperature uniform throughout the bath. Sometimes air gets entrapped and the pump does not work. In such case to remove the entrapped air, connect the discharge copper pipe of the pump to a rubber or any other suitable tube and such water from the other end. The machine is suitable for operation on 230 Volts 50 Cycles single phase AC supply. Specimen : Clean ductility mould and base plates. Assemble the mould on base plates. Coat the top surface of the plates and interior surfaces of the sides of moulds with mercury a mixture of equal parts of glycerin. Take enough bituminous material to be tested to fill mould. Completely melt the material to a temperature of 75oC to 100oC above the approximate softening point until it becomes thoroughly fluid. Then strain it through 300 micron IS sieves and after through stirring pour into mould. In filling such mould pour the material in a thin stream back and forth from and to end of the mould until it is more than level full. Leave the moulds to cool at room temperature for 30 to 40 minutes, then placed them in Water Bath of the Ductility Testing Machine previously set ready and maintained at 27.0 - 0.50oC ( unless testing temperature other than this is specified) for 30 minutes. For setting the Water Bath ready to procedure is as follows. Fill the Water Bath with water to the extent that it would stand about 10cm above the bitumen material briquette when fitted at a later stage on the brackets. Set the thermostate at 27oC. Put on the switches marked ‘STIRRER’ and 'HESTER' on the switches board. In summer when room temperature of water is higher then 27oC the heater need not be put to use, control the temperature at 27oC by adding cool water when ever temperature tends to rise above 27OC. By all arrangement keep the temperature in the Water Bath uniformly at 27oC. After the lapse of 30 minutes take out the moulds from the Water Bath and cut off the excess bitumen by means of a hot straight edged putty knife or spatula so that each mould is just level full. Place back the base plate and mould with briquette specimen in the Water Bath and keep at the specified temperature for about 85 to 95 minutes. Test Procedure : At the lapse of 85 to 95 minutes remove the base plates with moulds briquette specimen from the Water Bath. Remove the briquette mould from the base plate, catch the side pieces and let the end clips remain fitted to the briquette specimens. Mount the briquette specimens on the brackets. The holes in the clips of the moulds should slide in the pens on the opposite brackets. Note the initial reading on the scale. Before starting the motor, confirm that the water in the Water Bath is at a level about 10cm above the top surface of the briquettes. If necessary add more water at about 27oC into the Water Bath to achieve this objective. The Water Bath is already set to maintain the temperature of 27oC. By all arrangement keep the temperature is the Water Bath at 27oC. See that initially the clutch is disengaged. See the speed selector to give the rate of pull of 5cm minute. Switch on the motor. Pull the clutch handle to start the rotation of the lead screw which moves the moving bracket and causes stretching of the bituminous material standard briquettes in between the clips, until the briquettes are ruptured. Take the final reading on the scale as indicated by the pointer when each briquette is ruptured. From the initial reading and the final reading calculate the distance in centimeters through which the clips of each briquette have been pulled to produce rupture. When the last briquette ruptures the movement of the movable bracket by operating the clutch to disengage position takes the average of the elongation in centimeters of the three briquettes specimen at the ductility of the sample. Maintenance : Clear the moulds from sticking on the material. Empty the water from the bath if the instrument is not likely to be used for some time. Keep the lead screw well lubricated with oil or light grease. Keep the chain drive oiled. Keep the instrument clean. Spares If Required : Mould made of brass/gun metal has two end clips, two sides with knurled screws & side support for proper assembly.
