GENERAL DESCRIPTION
 
Most Standards make degassing oven of the PAV-aged asphalt samples mandatory. The Vacuum Degassing Oven (VDO) is designed to remove air bubbles created during accelerated oxidative ageing of asphalt binder by the PAV. This final conditioning makes the aged binder suitable for further tests such as BBR, DSR, penetration, ductility, softening point and many more.

The apparatus consists of a stainless vacuum vessel with encased band heaters and integlral vacuum and temperature controls. A platinum RTD measures internal test temperature to +/- 0.1° C. Selectable test temperatures (from ambient to 200° C) are controlled to +/- 4.0° C.

The Vacuum Degassing Oven VDO can be used as part of your Superpave performance based testing program.

Vacuum is provided by an integrated vacuum system and monitored by a pressure transducer and controlled to achieve 15 kPa absolute pressure.Temperature and vacuum are indicated both as set points and as actual values on the 6" digital color touch screen display. Temperature and vacuum calibratin can be site executed. Data logs of both temperature and vacuum are saved on USB stick or transferred to PC at the end of the test.

The vacuum chamber can accept either eight 55x35 mm or four 70x45 mm (available as accessories) sample containers. The instrument is supplied complete with temperature traceable calibration certificate, 8 aluminium 55x35 mm sample containers,a  double face sample holder and operator's manual.
