Effects of Storage on the Linear Viscoelastic Response of Polymer-Modified Asphalt at Intermediate to High Temperatures
… in the area of improved roadway performance is polymer-modified binder. The complex behavior of polymer-modified binders, particularly over time, is not yet well-understood by engineers. Therefore, an experimental study was performed to determine the effects of four years of storage at room …

Evaluation of binder grades on rutting performance
… WVDOH, has implemented the Performance Grade binder specifications for all paving projects and Superpave for high volume road projects. The standard binder specified in the state is a PG 64-22; for high volume roads a PG 70-22 is specified. These binders appear to be working well for most …

Laboratory investigation of fatigue endurance limits in asphalt concrete
… failure criterion. In addition, the effect of polymer-modified binder on the FEL of HMA materials is investigated. The addition of modified binder to the SP-II mixture reduced the estimated FEL by 27%. On the other hand, the addition of modified binder to the SP-III mixture improved its …

Development of a long-term durability specification for polymer modified asphalt
In recent years an increased use of polymers has occurred to modify asphalt binders, mainly to decrease pavement rutting but also to improve binder failure strain in direct tension. Whereas all of these effects positively impact the durability of polymermodified pavements, a need exists to quantify …

The Use of Atomic Force Microscopy in Evaluating Warm Mix Asphalt
… topographic and phase images for the asphalt binders. Two types of performance grade binders were evaluated in this study: a neat asphalt binder PG 64-22 and a polymer modified binder PG 70-22M. Four WMA technologies were investigated: Advera, Sasobit, Evotherm Advera, and foamed WMA. The …

Development and validation of a novel testing procedure for the evaluation of rutting susceptibility of bituminous binders.
… of rutting susceptibility of different asphalt binders thorough various parameters and correlating them with parameters resulted from tests carried out on their corresponding mixtures. Several factors influence the occurrence of rutting in asphalt mixtures including aggregate properties, …
