Abstract: Three different concentrations of crumb rubber were mixed with two different asphalts by means of a wet process to investigate the effect of rubber particles on the fundamental internal structure of asphalt binders with ...

Abstract: A study involving two rolling-thin-film-oven–aged asphalts and their blends with 15 and 50% of extracted reclaimed asphalt pavement (RAP) binders was conducted to investigate the effect of RAP content and properties on the ...

Abstract: Constitutive equations for asphalt binders and mixtures are important for predicting pavement performance, characterizing their flow behaviors, and establishing databases. To choose a proper constitutive equation, material ...

Abstract: This study evaluated several promising laboratory aging methods for simulation of field aging of asphalts. The rheological properties of an asphalt binder after aging in the thin-film oven test (TFOT) and rolling thin-film ...

Abstract: Viscoelastic materials exhibit rate- and temperature-dependant behavior in terms of stress-strain response and fracture. As a representative of this class of materials, rate-dependant fracture should be expected for the ...

Abstract: Experiments were performed to investigate the impact on the moisture resistance of paving mixtures of the addition of hydrated lime directly to the asphalt prior to mixture preparation. Moisture resistance was evaluated ...

Abstract: The rheological and chemical properties of hydrated lime-polyphosphoric acid (PPA)–modified asphalt binders before and after laboratory oxidative aging were investigated through dynamic shear rheometer (DSR) and nuclear ...
