Healing characteristics of asphalt binder

Construction and Building Materials, 2012
Abstract The healing performance of asphalt binder has a critical impact on the fatigue performance of asphalt binders, mixture and pavement. Although studies of the healing characteristics of asphalt binder can be found in some references, the subject has not been researched thoroughly. No universal healing evaluation index currently exists, and the

Chemical and Rheological Characterization of Asphalt Binders: A Comparison of Asphalt Binder Aging and Asphalt Mixture Aging

Transportation Research Record: Journal of the Transportation Research Board, 2022
The objective of this study was to compare the chemical and rheological properties of asphalt binders recovered from aged asphalt mixtures with the corresponding aged asphalt binders used in those mixtures. Seven plant-produced asphalt mixtures, with unmodified and polymer modified asphalt binders and varying reclaimed asphalt pavement (RAP) content ...

Rheological behaviors of epoxy asphalt binder in comparison of base asphalt binder and SBS modified asphalt binder

Construction and Building Materials, 2015
Abstract Epoxy asphalt binder is a completely different thermosetting paving material from traditional modified asphalt binders. To character its properties, standard test method of tensile properties for plastics is borrowed. However, the correlations within tensile properties and road-paving properties like i.e. temperature stability and durability

Creep Properties of Asphalt Binder, Asphalt Mastic and Asphalt Mixture

2021
For designing asphalt materials resistant to permanent deformation and rutting, a low creep deformation at high temperature is the crucial performance property. Usually, creep deformation is assessed through static or cyclic compression tests at elevated temperature, both for asphalt mixtures as well as for asphalt binders. For asphalt mixtures, static

Nonlinear rheological behaviors of epoxy asphalt binder compared to base asphalt binder and SBS modified asphalt binder at above ambient temperatures

Construction and Building Materials, 2020
Abstract When heavy vehicles load at high temperatures, the mechanical responses of asphalt binders are probable in the nonlinear viscoelastic regions. However, the nonlinear viscoelasticity of asphalts at above ambient temperatures is seldom studied.

Observation of asphalt binder microstructure with ESEM

Journal of Microscopy, 2017
SummaryThe observation of asphalt binder with the environmental scanning electron microscope (ESEM) has shown the potential to observe asphalt binder microstructure and its evolution with binder aging. A procedure for the induction and identification of the microstructure in asphalt binder was established in this study and included sample preparation ...
