Evaluating fatigue resistance of toner-modified asphalt binders using the linear amplitude sweep test
This paper examines the effect of waste toner on fatigue resistance of asphalt binder. Fatigue resistance of toner-modified asphalt binders was studied implementing the linear amplitude sweep test, which has been approved by AASHTO as a provisional standard and is currently being considered as a specification test for evaluating fatigue resistance of original and modified asphalt binders. The linear amplitude sweep is a cyclic torsion test conducted with a dynamic shear rheometer (DSR) which uses increasing loading amplitudes to accelerate the damage process. In order to characterise a waste toner as an additive for modifying an original asphalt binder, the XRD test has been done. DSR test results were used to determine fatigue resistance parameters and dissipated energy ratio to investigate fatigue behaviour of toner-modified asphalt binders. This paper argues that the improved fatigue resistance properties of toner-modified asphalt binders are reflected in the enhancement of the number of loading cycles, shortening crack length and degrading dissipated energy which remains in the specimens.
