Ductility Test Arrangement

Product Description

In the flexible pavement construction where bitumen binders are used. It is of significant importance that the binders form ductile thin film around the aggregates. This serves as a satisfactory binder in improving the physical interlocking of the aggregates. The binder material which does not possess significant ductility would crack and thus provide previous pavement surface. The ductility is expressed as the distance in centimeters to which a standard briquette of bitumen can be stretched before the thread breaks.

 The instrument is designed as per IS:1208 and consist the following: 

Three nos. of moulds mounted on a base plate, each mould has two end clips, two slides with knurled screws and side support for proper assembly on the base plate. One spare mould with base plate for casting the specimen also supplied

One Water bath of approx. 10-liter volume with a perforated shelf, provided with a thermostatically controlled heater.

The machine has two rates of travel i.e. 5cm/min and 1 cm/min. A clutch arrangement is provided by which the movement of the moveable bracket can be arrested or restarted without switching the motor off. Suitable to work on 220V ~, 50Hz.

Accessories and spares: Ductility mould with the base made of Gun metal.
