Advanced Technocracy Inc. is Manufacturer, Exporter & Supplier of DUCTILITY TESTING APPARATUS
In flexible pavement construction, bitumen binders are used. It is important that bituminous material forms ductile thin film around the aggregates, Which serves as a binder. The binder material not of sufficient ductility render spervious pavement surface and leads to development of cracks. Therefore it is important to carry out the ductility tests on bituminous material. Ductility is defined as 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 50mm/minute 25mm per minute at a temperature of 27degC +/-0.5degC.
The rotating shaft has 2 speeds of travel for the bracket, 5cm/min and 1 cm/min.selected by a clutch. Water bath inside is aluminum, 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, stirrer, heater and indicator lamps are fixed at a convenient place on the water bath, complete with three briquette molds and one base plate, all made of brass. Operates on 230 volts A.C. single phase.
