A THIN FILM ACCELERATED AGING TEST FOR EVALUATING ASPHALT OXIDATIVE AGING (WITH DISCUSSION)

An accelerated laboratory aging test is described in which asphalt is oxidatively aged as a thin film at elevated temperatures in a rolling thin film oven bottle to simulate the level of oxidative age hardening that typically occurs during extended pavement aging. The test is a modification of the Schmidt rolling microfilm (RMF-C) test. The sample size has been increased from 0.5 g to 4.0 g to provide sufficient sample for chemical and rheological evaluation of the aged asphalt. In the test, volatile loss, the level of chemical oxidation, and the increase in viscosity are similar to those which occur during field aging.
