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 ...

Preparation of TiO2/PS-rGO incorporated SBS modified asphalt with enhanced resistance against ultraviolet aging

, 2021
Ultraviolet (UV) radiation has detrimental effects on the service time of asphalt pavement. To effectively mitigate these impacts, Titanium dioxide/polystyrene-reduced graphene oxide (TiO2/PS-rGO) was synthesized and applied as an anti-UV aging agent for

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.

The viscoelastic properties of polymer‐modified asphalts

The Canadian Journal of Chemical Engineering, 2000
AbstractThe linear viscoelastic properties of one family of base asphalts, unmodified or modified by the simple addition of an elastomer or by further in‐situ crosslinking, have been investigated. The time‐temperature superposition principle was shown to be valid for the base as well as for the modified asphalts.

Comparison of quantitative determination for SBS content in SBS modified asphalt

, 2021
It is vital for the quality assurance of SBS modified asphalt to determine the SBS content accurately in modified asphalt. In the present work, radial and linear SBS were used to modify asphalt with different addition amount, then three calibration ...

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
