Accumulated strain in polymer-modified asphalts

Rheologica Acta, 2007
One of the distress modes of asphalt pavements is the rutting that occurs at high operating temperatures, and it is believed that the accumulated strain in asphalt binder is mainly responsible for the rutting. The asphalt industry has tried to use the parameter 1/J″ as the specification parameter for the determination of the susceptibility of asphalt ...

Comparative Field Evaluation of Shale Oil–Modified Asphalt with Polymer-Modified Asphalts

Transportation Research Record: Journal of the Transportation Research Board, 1996
Since the discovery, patenting by Western Research Institute, and licensing to The New Paraho Corporation of a concept for the use of an asphalt modifier that can be produced from western shale oil, nine test strips have been constructed in five states in the United States.

Bio-Renewable Asphalt Modifiers and Asphalt Substitutes

2011
The global asphalt market is to reach 118.4 million metric tons by 2015, according to a January 2011 report by Global Industry Analysis, Inc. The asphalt paving industry accounts for the largest end-use market segment of asphalt. With increasing growth in the developing markets of China, India, Brazil, and Eastern Europe, asphalt will be needed to ...

Temporary networks in polymer‐modified asphalts

Polymer Engineering & Science, 2004
Abstract The viscosity functions of several polymer‐modified asphalts (PMAs) were studied at different temperatures in steady‐state rate sweep tests. The materials were obtained by mixing different base asphalts with either styrene‐butadiene‐styrene (SBS), ethylene‐vinylacetate (EVA) or reactive ethylene terpolymers (RET).

Viscosity function in polymer-modified asphalts

Journal of Colloid and Interface Science, 2003
Asphalt is a multidisperse micellar system with rheological behavior resembling that of a low-molecular-weight polymer. Nowadays, asphalt is frequently modified by blending it with various polymers. Such modified asphalt has rheological properties that differ from the properties of the base asphalt.

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 ...

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

Memory functions in polymer modified asphalts

Journal of Applied Polymer Science, 2007
AbstractThe viscoelastic nonlinear behavior of several base and polymer modified asphalts (PMA) has been studied in step‐strain experiments. The polymers were poly(styrene‐b‐butadiene‐b‐styrene), poly(styrene‐b‐ethylene‐co‐butylene‐b‐styrene), poly(ethylene‐r‐vinylacetate) copolymers, and a linear low density poly(ethylene), which were chosen as ...

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.
