Evaluation of Fatigue Behavior of Bitumen Binders by the Linear Amplitude Sweep Test: Failure Criteria and Fatigue Parameters
The influence of test temperature, aging, and modification of bitumen PG58-28 with active powder of discretely devulcanized rubber on damage accumulation rate curves; fatigue parameters Nf, FREI, and F; and postpeak slope of the τ(γ) curve is analyzed on the basis of processing of experimental data of the linear amplitude sweep test using three models based on the VECD theory, five destruction (failure) criteria, and two variants of calculating the α parameter (19 variants in total). It is shown that, at small deformations, parameter Nf decreases with decreasing temperature, but increases after operational aging, while parameters FREI and F change in the same direction with aging and decreasing test temperature—parameter F increases, and parameter FREI decreases. The modification resulted in a decrease in F, an increase in FREI, and a decrease in the slope of the F and FREI curves versus temperature, as well as a decrease in the postpeak slope of the τ(γ) curve.
