Rheological properties of bituminous mastics containing chemical warm additive at medium temperatures and its relationship to warm mix asphalt fatigue behavior

Experimental study of Compression-Tension asymmetry in asphalt matrix under Quasi-static and dynamic loads via an integrated DMA-based approach

“…To determine the rheological parameters of asphalt binder, the dynamic shear rheometer (DSR) is commonly used by applying shear loads in different conditions [1]. According to the standard AASHTO TP101-12 [2], frequency sweep test and amplitude sweep test performed on DSR can determine the rheological parameters and the damage characteristics of asphalt binder, respectively [3][4][5][6]. With the frequency sweep test at very low strain amplitude, the two key parameters, namely complex shear modulus (G * ) and phase angle (𝛿) can be measured to evaluate the resistance of asphalt binder to shear deformation in the linear visco-elastic region.…”
