TL;DR: In this article, the authors evaluated the rheological properties and chemical bonding of nano-modified asphalt binders blended with nanosilica and found that the nanosilsilica was added to the control asphalt at contents of 4% and 6% based on the weight of asphalt binder.

TL;DR: In this paper, the rheological properties of nano-modified asphalt were analyzed by use of asphalt binder tests such as Rotational Viscosity (RV), Dynamic Shear Rheometer (DSR), and Bending Beam Rheometers (BBR).

TL;DR: In this paper, the applicability of carbon micro-fiber and nanoclay in asphalt binders was investigated and the performance of micro- and nano-modified asphalt (NMA) binders in terms of rheological properties.

TL;DR: In this article, the authors evaluated the moisture susceptibility, rutting, and fatigue resistance of laboratory-made half warm mix asphalt (HWMA) mixtures containing moist aggregates and recycled materials such as manufactured roofing shingles and reclaimed asphalt pavement (RAP).

TL;DR: In this article, the authors developed a test method to identify aggregate reactivity in the presence of deicing chemicals yielded a mortar bar test (EB-70 test) based on soaking the mortar bars containing the suspect aggregates in a 6.4 molar potassium acetate (6.4 M KAc) deicer solution, instead of a 1 normal sodium hydroxide (1 N NaOH) solution, as in the standard ASTM C1260 test.
