TL;DR: A review of research that has been conducted on polymer modified binders over the last three decades can be found in this paper, where the elastic recovery test is good at determining the presence of polymers in an asphalt binder but is less successful at predicting field performance of the pavement.
836 citations
TL;DR: In this paper, the use of crumb rubber in asphalt paving mixture has long been proven successful due to good compatibility and interaction between rubber particles and asphalt binder, leading to various improved properties and performance of asphalt mixtures.

TL;DR: The current state of knowledge on the fundamentals of bitumen recovery from Athabasca oil sands using water-based extraction methods is reviewed in this paper, where the bitumen extraction process is discussed and analyzed as individual steps: oil sand lump size reduction, bitumen liberation, aeration, flotation and interactions among the different components that make up an oil sand slurry.
Abstract: The current state of knowledge on the fundamentals of bitumen recovery from Athabasca oil sands using water-based extraction methods is reviewed. Instead of investigating bitumen extraction as a black box, the bitumen extraction process has been discussed and analyzed as individual steps: Oil sand lump size reduction, bitumen liberation, aeration, flotation and interactions among the different components that make up an oil sand slurry. With the development and adoption of advanced analytical instrumentations, our understanding of bitumen extraction at each individual step has been extended from the macroscopic scale down to the molecular level. How to improve bitumen recovery and bitumen froth quality from poor processing ores is still a future challenge in oil sands processing.
