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 ...

Interaction nonlinearity in asphalt binders

Mechanics of Time-Dependent Materials, 2011
Asphalt mixtures are complex composites that comprise aggregate, asphalt binder, and air. Several research studies have shown that the mechanical behavior of the asphalt mixture is strongly influenced by the matrix, i.e. the asphalt binder. Characterization and a thorough understanding of the binder behavior is the first and crucial step towards ...

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.

Polymer Modified Asphalt Binders

1992
Description Peer-reviewed papers discus the use of elastomers such as styrene block copolymers, latex rubber, and various plastomers that include EVA and polyethylene. In 2 sections: laboratory studies of polymer modified asphalt binders for it mix asphalt; and emulsions and full scale field experiments which explore construction aspects

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,

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.

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

Improving Asphalt Binder’s Elasticity through Controlling the Interaction Parameters between CRM and Asphalt Binder

Advances in Civil Engineering Materials, 2020
Abstract Crumb rubber modifier (CRM) is considered one of the most commonly used modifiers that enhances the rheological properties of asphalt binders. Optimizing the interaction process between CRM and asphalt binder to enhance the asphalt binder’s elasticity without additional additives is the main purpose of the article.

Asphalt and binder evaluation of asphalt mix with 70% reclaimed asphalt

Road Materials and Pavement Design, 2017
With modern recycling technologies, reclaimed asphalt (RA) has been successfully used in new hot mix asphalt (HMA). However, even if the conventional technical specifications on binders and asphalt mixtures are met, HMA produced with high amount of RA, 50% and higher, may show poor performance behaviour.
