Abstract: This article concerns the modeling of the dynamic behavior of flexible pavement under dynamic solicitation. It uses the finite element method and integrates the complex modulus of the bituminous materials in a frequency ...

Abstract: Rutting, due to permanent deformations of unbound materials, is one of the principal damage modes of low traffic pavements. Flexible pavement design methods remain empirical; they do not take into account the inelastic ...

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. ...
