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

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.

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

Low-Temperature Thermal Cracking of Asphalt Binder by Asphalt Binder Cracking Device

Transportation Research Record: Journal of the Transportation Research Board, 2006
An asphalt binder cracking device (ABCD) is proposed to determine the low-temperature cracking potential of an asphalt binder. ABCD is a simple test method; the operating principle is based on the differential thermal contraction between the metal ABCD ring and an asphalt binder placed outside the ring.

Modifying Complex Additive for Asphalt Binder

Chemistry and Technology of Fuels and Oils, 2016
© 2016 Springer Science+Business Media New York.The effect of modifying complex additives on the physicochemical properties of asphalt is studied. It is shown that complex additives based on cellulose fibers with surfactants adsorbed on their surfaces possess a cross-linking effect and improve the heat and frost resistance of the asphalt binder and its

Thermorheological properties of asphalt binders

The Canadian Journal of Chemical Engineering, 2020
AbstractThe rheological properties of different types of asphalt binders were studied and compared considering their constituents and physical characteristics. The saturate, aromatic, resin, and asphaltene (SARA) analysis and differential scanning calorimetry (DSC) have shown their individual constituents and two distinct glass transition temperatures,

Thixotropic Characteristics of Asphalt Binder

Journal of Materials in Civil Engineering, 2011
Asphalt binder has thixotropic characteristics that significantly affect its overall performance, but specifically fatigue performance, healing performance, and high temperature performance. Therefore, a clear understanding of the thixotropy of asphalt binder, together with proper modeling, is useful in researching the performance of the material ...
