ABSTRACT
One of the most common failures of bituminous mixtures is fatigue, which is why many authors have investigated this phenomenon, mainly based on individual studies of the bitumen or the bituminous mix. The aim of this work is to establish a correlation between the fatigue behavior of bitumens with the fatigue behavior of bituminous mixes made with them. For this, laws have determined fatigue different conventional bitumens and polymer modified by testing in the dynamic shear rheometer (DSR) and the corresponding mixtures of flexural dynamic tests.

KEYWORDS:
Fatigue, Bitumen, Bituminous mixture, Deformation criticism, Rheology, polymer modified bitumen (BMP), dynamic shear rheometer (DSR), dynamic Flexotración.
