Abstract: After a comprehensive experimental program on asphalt mastic modified with styrene-butadiene-styrene (SBS) and polyphosphoric acid (PPA) with two filling ratios of 18% and 35%, in this paper, a biphasic finite-element ...

Abstract: The dynamic shear rheometer was used to investigate the effect of polyphosphoric acid (PPA) and styrene-butadiene-styrene (SBS) modification on the rheological and mechanical behavior of asphalt binder and asphalt mastic. ...

Abstract: The fatigue behavior of bituminous composites was investigated at different length scales—bitumen, mastic, mortar, and asphalt mixture. The stress sweep test, as the initial test, and the dynamic modulus test, as the primary ...
