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:
Construction: CE certified vertical stainless steel pressure vessel with encased band heaters and integral pressure measurement control. Temperature is measured by Platinum RTD.
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. Power supply: 230V 1Ph 50/60Hz 10A
Dimensions: 760x460x700 mm.
Weight: 130 kg approx.
NOTE: a source of compressed air with a pressure of at least 325 psi and a pressure regulator is required to operate the PAV.
