B091M Pressure Ageing Vessel (PAV)

The unit has been developed to simulate the accelerated ageing of bitumen and bituminous binders after 5 to 10 years. The sample is exposed to high pressure and temperature for 20 hours, to simulate the effect of a long time oxidative ageing by verifying the penetration and softening point characteristics.

PAV features include:

• Touch screen controller with front panel user interface with easy to use step-thru operation.
• Bench top unit with integral vessel/oven design.
• USB port on front unit with software upgrades and data storage.
• Remote capabilities: with APP control PAV with smart phone, tablet or IPad.
• Timer to set time and date for automatic preheat.

Construction: CE certified vertical stainless steel pressure vessel with encased band heaters and integral pressure measurement control. Temperature is measured by Platinum RTD.

Specifications:

• Operating pressure: 2.1 +/- 0.1 Mpa
• Temperature range: 80°C to 115°C, res: 0.1°C
• Test temperature uniformity: +/- 0.5°C
• Time to return to set point temperature: less than 60 min.

The unit is supplied complete with:

• 10 specimen pans AASHTO T179;
• O-Ring; precision anodized aluminum sample rack;
• Hex socket wrench;
• specimen loading/unloading tool;
• single stage regulator;
• high pressure hose assembly;
• instruction manual.

NOTE: a source of compressed air with a pressure of at least 325 psi and a pressure regulator is required to operate the PAV.
