Standard Ductilometer for Ductility test - Ductimeter
Standard : EN 13398, ASTM D113, AASHTO T51, ASTM D6084
Model : 81-PV10A02

ASTM D113 : 1.1 The ductility of a bituminous material is measured by the distance to which it will elongate before breaking when two ends of a briquet specimen of the material, of the form described in Section 4, are pulled apart at a specified speed and at a specified temperature. Unless otherwise specified, the test shall be made at a temperature of 25 6 0.5°C and with a speed of 5 cm/min 6 5.0 %. At other temperatures the speed should be specified.

General Descriptions :

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. To obtain the required 25° with ± 0.02° C tolerance, circulation of cold water is necessary. 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 within ± 0.2° C
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.
