OVERVIEW

This test is used to measure the combined effects of heat and air on a thin film of bitumen or bituminous binder in permanent renewal.

Test Method

Determines the effect of heat and air on a moving film of asphalt to serve as an indicator of approximate change in properties during conventional hot-mixing. The results are reported in terms of the changes in selected properties such as viscosity, penetration, and ductility brought about by the RTFO test, as evidenced by test data taken before and after the 75-minute oven cycle.

SPECIFICATIONS

Double-walled electrically heated convection oven for rolling thin film oven tests on asphalt. Incorporates all required features per ASTM specifications, including a door with double-pane viewing window; symmetrical top and bottom vents; air plenum; squirrel cage-type 1725rpm fan; digital indicating thermostat to control oven temperature at 163°C ±0.5°C; vertical circular carriage to mechanically rotate the samples at 15 ±0.2rpm; air jets to blow heated air into each sample bottle at its lowest point of travel; and a calibrated flowmeter to control the airflow at 4000mL/min. An over-temperature cut-off circuit disconnects power to the unit in the event of control failure.

FEATURES

  • Invented, designed, and manufactured in California.
  • Super accurate P.I.D. controller.
  • Low thermal mass RTD.
  • Over-temperature safety cut-out.
  • Double-walled temperature cabinet.
  • Unique temperature control suppression.
  • Made in India.
