High-Float Emulsion Residue: A New Rheological Model Based on the Existence of a Yield Stress
DownloadFall 2016
“High-float” (HF) emulsions are dispersions of micron-sized bitumen droplets in water, with a special type of anionic surfactant functioning as stabilizer. By allowing the water to evaporate from an HF emulsion, what remains is called a “high-float emulsion residue.” Although indistinguishable in...

The rheology of asphalt binders is an important factor in the design and construction of roads. As polymer modification is now often required to meet performance demands, the rheological behaviour of the binders has become increasingly complex. Within the past decade, a new method to evaluate...

The addition of coarse particles to a flocculating fine particle slurry increases the Bingham yield stress of the resulting mixture, which can drastically alter the laminar-to-turbulent transition velocity. The objective of this study is to quantify the effect of coarse particle size and volume...
