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 ...

Nanoclays as Asphalt-Binder Modifiers

2013
Among the solutions to reduce failures of road pavements, polymer-modified asphalts (PMAs) represent the most effective one and have been adopted worldwide in the last decades. PMAs are blends of asphalt and a polymer, where the latter is swollen by the bituminous material, thus forming a network whose structure closely resembles that of gels ...

Rheology and microstructure of asphalt binders

Rheologica Acta, 2001
The viscous and linear viscoelastic properties of different asphalt binders have been analyzed in this paper. Thus, an unmodified bitumen, a polymer-modified (SBS) bitumen, a commercial synthetic binder, and two model synthetic binders with different polymer (SBS) concentrations have been studied.

Detection of Polymers in Asphalt Binders

Transportation and Development Institute Congress 2011, 2011
Superpave™ performance-graded asphalt binder technology continues to advance with some producers focusing on the use of additives to enhance the performance of asphalt binders. A common practice is to modify an asphalt binder with a polymer to extend the high- and low-temperature range.

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,

Effect of Chemical Components of Asphalt Binders on Fatigue Resistance of Binder and Asphalt Mixtures in High Reclaimed Asphalt Pavement Mixtures

Journal of Testing and Evaluation, 2021
ABSTRACT In this paper, correlations between the chemical components and fatigue parameters of the binder blends containing reclaimed asphalt binder (RAB) were evaluated. Fatigue resistance of RAB-containing binder blends were evaluated by dynamic shear rheometer and linear amplitude sweep tests.

Fracture mechanics and asphalt binders

Road Materials and Pavement Design, 2006
ABSTRACT In this paper, the applicability of linear elastic, elastic plastic, and time-dependent (viscoelastic) fracture theories to asphalt binders at lower service temperatures is examined. Linear elastic fracture mechanics was found to be applicable only at temperatures below the glass transition temperature.

Polymer modified asphalt binders

Construction and Building Materials, 2007
Abstract This paper is a review of research that has been conducted on polymer modified binders over the last three decades. Polymer modification of asphalt binders has increasingly become the norm in designing optimally performing pavements, particularly in the United States, Canada, Europe and Australia.

Durability assessment of asphalt binder

Construction and Building Materials, 2018
Abstract Test results are presented for 24 asphalt binders with the aim to compare various measures of durability. Surprisingly high correlations were found between disparate measures of durability but practical considerations make certain tests preferable. A comparison is provided between AASHTO M 320 grades, critical crack tip opening displacements,

Rheology of warm mix asphalt binders with aged binders

Construction and Building Materials, 2011
Abstract This study addresses the rheological investigation of properties of warm mix asphalt (WMA) binders containing long-term aged binders. The recycled binders with the additives were produced using two (i.e., zeolite Aspha-min® and wax Sasobit®) of the available warm asphalt processes.
