A study on the oxidation kinetics of warm mix asphalt ...

15/11/2015  The principle objective of this work was to study the oxidation kinetics of warm mix asphalt materials by aging a PG 70-22 base binder with and without warm mix additives and to assess the potential impact of differences on pavement oxidation using a pavement oxidation model. Changes in CA under multiple time/temperature combinations provided ...

Asphalt Aging: Dual Oxidation Mechanism and Its ...

01/01/1998  The kinetic data and chemistry of asphalt oxidative age hardening suggested a sequential, dual mechanism for asphalt oxidation. The dual mechanism rationalizes conflicts between earlier mechanistic investigations and explains the hyperbolic-like, time-versus-property plots characteristic of asphalt oxidative aging. The oxidation kinetics provide further

Evaluation of binder aging and its influence in aging of ...

Binder oxidation in pavements and its impact on pavement performance has been addressed by numerous laboratory studies of binder oxidation chemistry, reaction kinetics, and hardening and its impact on mixture fatigue. Studies also have included some work on binder oxidation and hardening in pavements and the effectiveness of maintenance treatments. Yet more such

A new short-term aging model for asphalt binders based

24/06/2019  This production process, on one hand, facilities the oxidation between oxygen and asphalt binder due to thin asphalt binder films, on the other hand, it enables the heating to volatilize the lighter fractions (i.e. aromatic and resin) from the binder and increase the larger and stiffer fraction (i.e. asphaltene) [16, 17]. Thus, the short-term aging can be described as a

Prediction of Complex Shear Modulus and Fracture ...

influential aspect of asphalt binder aging is oxidation. ... predicted using the oxidation kinetics model as a function of aging time and temperature. Block 1 32 . Conclusion The log crossover frequency and log crossover modulus are highly linearly correlated with aging time for both neat and modified binders. The CA model can be used to predict complex modulus and phase
