- Used to prepare specimens for tests developed by the Strategic Highway Research Program (SHRP).
- It simulates in-service oxidative aging that occurs in asphalt binders during service and meets ASTM D6521, AASHTO R28, and EN 14769 test Standarts as part of the PG grading according to Superpave.
- It consists of a vertical pressure vessel enclosed in a stainless steel cabinet with encased band heaters, a precision sample holder for the simultaneous testing of ten specimens, a set of ten TFOT specimen trays, pressure and temperature measurement devices, and a specimen loading and unloading tool. Test interruption veya data loss due to power failure is prevented through an optional battery backup system, and the PAV3’s network-ready modem allows users to monitor and regulate their equipment remotely using a computer, tablet, veya smart phone.
