The Evaluation of Rheofalt as a Warm Mix Asphalt Additive on the Properties of Asphalt Binder

In this research study, Rheofalt as warm additive was used to modify original binder (60-70 penetration grade). The binder fatigue and rutting performance was evaluated through Linear Amplitude Sweep (LAS) and multiple stress creep and recovery (MSCR) test, respectively. Results indicated that the b...

Description
Summary:In this research study, Rheofalt as warm additive was used to modify original binder (60-70 penetration grade). The binder fatigue and rutting performance was evaluated through Linear Amplitude Sweep (LAS) and multiple stress creep and recovery (MSCR) test, respectively. Results indicated that the binder modified with 2% rheofalt has the highest J nr value which lead the pure binder more susceptible to rutting. The LAS test results demonstrated that the fatigue behavior of asphalt binders modified with 2% rheofalt is the highest one.
