Pressure Ageing Vessel PAV
EN14769, AASHTO PP1, ASTM
The device contain a pressure/temperature vessel made of Nirosta with connecting
elements, integrated in a coated steel casing with lid including clamping system acc.
European pressure guideline, pressure/temperature sensors as well as an
electronically controlled pressure/temperature unit with software.
A touchscreen PC with Windows® operating system and pre-installed testing
software allows a easy and fast conditioning up to ten bitumen specimen moulds acc.
EN 12607-2. Four different independent automatic test cycles with a test duration of
85°C/65 h, 90°C/20 h, 100°C/20h and 110°C/20 h allow a real time control of the
actual pressure and temperature. The conditiong cyle content including a automatic
preheating cycle of the system and a test cycle with constant data acquisition for
temperature and pressure. A pressure relief valve automatically depressuirized the
system during the test or in case of pressure overload. In case of electronic
interferences and interruption of the system is releasing the pressure automatically.
The Touch Screen is permanently connected to Pressure Ageing vessel by the
provided USB cable. To carry out the test it is necessary to have sufficient supply of
compressed air. The air is supported by Push-Lok® connection system from a
compressor or pressure cylinder. The whole system is CE-marked.
The operating languages are Italian, English, French, German, Portugiese, Polish
The mounting of the pressure vessel resp. the removal of the support frame is made
