  • 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.

Especificaciones

PAV SAMPLE HOLDER

  • The new PAV3 sample holder is one solid, sturdy unit with no assembly required.
  • Leveling is made easy with the vessel’s interior leveling ring, and a small bubble level between the slots further
    assures accurate verification.

INCREASED CONTROL OPTIONS

The PAV3 features programmable temperatures between 50°C and 150°C, and between 80°C to 115°C the
tolerance is well within ± 0.1°C. Pressurization is programmable from 1 hour to 99 hours. This enables AASHTO R28, ASTM D5621, and EN 14769 specifications to be met without any special programming, allowing greater freedom for
research and development projects.

DATA ACQUISITION

Temperature, pressure, and time data are collected throughout the aging process. This information is available to
view in real time on the touchscreen display, in the form of raw data or graphs. Once the aging process is complete, a .CSV file can be created and dowloaded onto a flash drive using the USB port on the front of the PAV3. The .CSV file
can then be easily manipulated using Microsoft Excel or other spreadsheet programs.
