Standard Ductilometer for Ductility test - PAVELAB SYSTEMS Ductimeter

• N° 4 tension line (briquette capacity) x 1500 mm carriage travel
• Closed loop PID temperature control system
• Stainless steel water bath with insulation
• Exclusive inbuilt thermoregulation system compensating the exchange of heat and cooling, resulting in a very strict temperature control.
• Speed range: from 5 to 100 mm/min
• High carriage return speed 500 mm/min

This method is used 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.

Conforming to the ASTM D113, D6084 and EN 13398 standards, the test is performed in water at a temperature of 25±0.5°C (ASTM/AASHTO) or 25±0.2°C (EN) at a constant speed of 50 mm/min.  Models 81-PV10A02, 81-PV10A04 fully satisfy these requirements.

Controls produce other advanced versions for the determination of the Tensile properties of modified bitumen by the Force Ductility method (EN 13589) and a Research version performing testing speed from 1 to 200 mm/min and suitable for testing at temperatures from -10 to +60°C.

Water bath
-Stainless steel water bath with insulation, heating system located on all base surface for better uniformity and cooling coil (for connection to water mains or chiller)distributed on 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  screws rods and mobile carriage  to perform test speeds from 5 to 100 mm/min. The system also permit the fast return of the carriage at the end of the test : 500 mm/min, to reduce the dead time and for more productivity. The carriage return is automatic so manual interventions are not required.
Temperature control
-By closed loop PID system which assure constant temperature within ±0.2°C
-Plate-type base heaters for better temperature uniformity
-Thermoregulation system based on the control of the heat supplied to the bath by the heater and the heat decrease by controlling the flow rate of the cooling coil. This important feature assure the temperature control within strict limits and permit the use of suitable standard chillers.
Control panel and elongation measurement.
Digital display control panel to set the testing speed: 5 to 100 mm/min with the carriage return function. Elongation measurement by linear scale.
