MAIN FEATURES

4 tension line (briquette capacity) x 1500 mm
Easy and free access to the large testing space
Closed-loop PID temperature control system
Stainless steel insulated water bath
Exclusive in-built thermoregulation system compensating the exchange of heat and cooling, resulting in a very strict temperature control, optimized by the connection to chiller (optional)
Adjustable speed range from 5 to 100 mm/min
High carriage return speed of 500 mm/min for greater productivity
Elongation measurement by encoder read on display

GENERAL DESCRIPTION

The ductility test is performed for determining the ductility of bituminous materials by measuring the elongation before breaking when two ends of briquette specimens are pulled apart at a specified speed and temperature.

This model fully satisfies and exceeds ASTM D113, ASTM D6084, AASHTO T51 and EN 13398 requirements. A water chiller (see accessories) is ideal for this and may already be available in the laboratory but mains water can also be used. If the ambient temperature goes over 25° C, as in the tropical areas, and cold mains water is not available, the use of a water chiller is mandatory.

Water bath

Insulated stainless steel water bath with a heating system located over the entire base surface and a cooling coil (for connection to water mains or chiller) distributed over the three side walls assuring temperature uniformity without water turbulence inside the bath. All parts in contact with water are made of stainless steel.

Carriage displacement

Double-screw rods and mobile carriage enable test speeds from 5 to 100 mm/min. The system also permits the fast return of the carriage at the end of the test (500 mm/min) to reduce dead time and increase productivity. The carriage return is automatic so manual intervention is not required.

Temperature control

A closed-loop PID system assures constant temperature
Plate-type base heaters give better temperature uniformity
The thermoregulation system is based on controlling the heater (which increases the temperature of the bath) and the flow rate of the cooling coil (which decreases the temperature). This important feature assures control of the temperature within strict limits and permits the use of suitable standard water chillers

Machine control and elongation measurement
Control panel with digital display to set the testing speed: 5 to 100 mm/min, with the carriage return function. Elongation measurement by encoder.

The machine can be completed with a transparent cover
