VACCUM OVEN | PAV
Specifications
For the application of AASHTO R28, ASTM D6521 standards for accelerated aging under pressure of bituminous binders.
The aging process of PAV bituminous binders leads to the formation of air bubbles in the exposed binders, which must be removed at the end of incubation.
The degassing enclosure was designed to carry out this step at temperatures between ambient and 200°C, under a vacuum of 15 ± 1 kPa as defined in the standard.
Enclosure consisting of the following
- Heating chamber (up to 200°C) in stainless steel, under sealed vacuum
- Hinged cover
- Temperature control by platinum probe
- Automatic air inlet valve at the end of the cycle
- Overheating safety
- 7″ Digital touch screen with real-time reading of temperature and pressure parameters
Operating modes
- Automatic: 170 +/- 4°C for 30 minutes,
- Semi-automatic: temp. from ambient to 200°C, 30 minutes cycle,
- Manual: temp. from ambient to 200°C, cycle from 1 to 99 minutes.
- Cycle pressure: 15 ± 1 kPa (display at 0.1 kPa)
