Title: EVALUATING RECYCLED ASPHALT BINDERS BY THE THIN-FILM OVEN TEST
Accession Number: 00602679

Availability: Find a library where document is available Abstract: Evaluation of long-term performance and identification of nonhomogeneity, incompatibility, and hardening rate of hot-mix-recycled bituminous pavement are described. The effects of artificial laboratory aging on a virgin binder (AC-20) and three other--extracted and recovered--rejuvenated binders were determined. Laboratory aging was achieved by means of the thin-film oven test (TFOT). Analysis and evaluation of the test data revealed some important aspects of hot-mix recycling. The TFOT was identified as a potential added criterion in identifying recycling agents that tend to cause a high rate of hardening, nonhomogeneity, and noncompatibility problems in recycled binders meeting the standard specifications of a virgin binder. This identification can be obtained by visually inspecting the residues after the TFOT and classifying their consistency using penetration and viscosity tests.
