Prediction of Linear Viscoelastic Response of the Loss Shear Modulus of Polymer-Modified Binders
… models, developed on straight asphalt binders, are inadequate to characterize the frequency dependence of response of polymer-modified asphalt binders. In an earlier study at Virginia Tech, mathematical models were developed to predict the storage and loss shear moduli of …

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 …

Characterization of Polymer Modified Asphalt Binders Containing Processed Oil
… and processed oil were added to the binder. The modified binders were also aged artificially using different procedures. The study found that adding processed oil to polymer modified binders reduces viscosity and improves workability, while the modifiers improve the rutting resistance of them, …

Rheological and nanomechanical characterization of aging in polymer modified asphalt
… aging is determined in the laboratory. Asphalt binders are aged using Rolling Thin Film Oven (RTFO), Pressure Aging Vessel (PAV), and draft ovens. Asphalt binder includes an unmodified base binder, Styrene-Butadiene (SB) and Styrene-Butadiene-Styrene (SBS) polymer modified binders. Rheological …

Viscoelastic Modeling of Straight and Modified Binders at Intermediate and High Temperatures
… of a new range of high performance asphalt binders. These new binders known as modified asphalt binders, have a more complex behavior than traditional binders. A review of the current mathematical models shows that most of them suffer from different drawbacks that make them inadequate for …

Evaluation of Balanced Asphalt Surface Mixtures with Conventional and High RAP Contents Using Laboratory and Accelerated Pavement Testing
… contents, recycling agents (RAs), fibers, and polymer-modified binders. Laboratory performance tests are essential to the BMD process, as they ensure the production of durable, high-performance materials. Beyond laboratory performance evaluation, accelerated pavement testing (APT) plays a …

Nano-scale evaluation of moisture damage in asphalt
… the study of asphalt chemistry, AFM tips are modified using chemical functional groups such as carboxyl (-COOH), hydroxyl (-OH), ammin (-NH3) and methyl (-CH3), representing the chemistry of asphalt binder. Thus functionalized tips facilitate the measurement of adhesion within the asphalt …

Impact of Anti-Strip Additives on Performance of Asphalt Pavements
… of typical HMA pavements.Aggregates and binders were obtained from five different sources: Alabama, California, Illinois, South Carolina, and Texas to produce HMA mixtures that were evaluated in this study. Three mix designs were conducted for each material source: un-treated, …
