Oxidative Aging of Asphalt Binders in Hot-Mix Asphalt ...

Jan 01, 2011  The oxidation changes in the binder had differing effects on the stiffness of the mixture as a function of age. Not only were the aggregate and mixture characteristics important to the mixture stiffness and aging relationship, but the binder characteristics themselves, in particular polymer modification, influenced the aging and stiffness ...

Asphalt Binder - an overview ScienceDirect Topics

Although the asphalt binder (also called asphalt cement) component typically comprises a minority of the asphalt–aggregate mix—approximately 5–6% (w/w) of the asphalt paving mixture—it does have a strong and meaningful effect insofar as the binder coats and binds the aggregate particles together.In fact, the selection of the proper grade of asphalt (asphalt cement or emulsion) for the ...

Understanding the Effects of Moisture on Hot Mix Asphalt

Of the various functional groups present in asphalt binder, carbonyls/ketones as well as sulfoxides have been used to explain asphalt binder properties (Weigal and Stephen, 2017; Peterson and Glaser, 2011). This study focuses on the carbonyl and sulfoxide groups due to their ability to detect aging in asphalt, as proven by Dony et al., 2016.

Jan 01, 2019  The dynamic modulus ( E * ) of asphalt mixtures is an important parameter in pavement design and analysis.Although the E * values of freshly prepared hot-mix asphalt (HMA) mixtures can be conveniently determined through laboratory tests, the E * values of field pavements continuously evolve as asphalt binder ages, and hence are difficult to determine.
