Semi-Automatic Aimco Digital Ductility Test Apparatus

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 digital temperature controller. Two rates�of travel i.e. 5 cm/min and 1cm/min are provided. 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 50�mm/min. � 2.5mm per minute at a temperature of 27�C � 2�C Suitable for operation on 220 V, 50 Hz, Single Phase, AC supply.
