Bitumen Ductility Testing Machine with Cooling Bath

Temperature-controlled ductility machine that stretches bitumen briquettes at 50 mm per minute to measure elongation before breaking. Used for paving grade and modified bitumen acceptance testing.

Specification

Standard bitumen briquettes are pulled apart in a thermostatic water bath at 27 or 25 deg C at a uniform speed, and the distance at which the thread breaks is read from a scale. The test indicates cohesion and flexibility of the binder. A refrigerated bath option supports low-temperature tests.

Features

• Stepper motor traction with 50 mm/min constant speed
• Stainless steel bath with insulation
• Digital temperature controller with circulation pump
• Travel scale up to 150 cm
• Supports 3 or 4 briquette moulds in one run
