Abstract
This paper documents and discusses performance-based specification properties of 36 asphalt binders. Materials were obtained from commercial sources and purposely distilled from Alberta oil sands crude oils (Athabasca, Cold Lake). Binders were evaluated according to regular Superpave™ specifications, Fraass test, and enhanced protocols based on limiting phase angles and complex moduli. From an overall performance perspective, sol-type binders made from Athabasca and Cold Lake, Alberta and Laguna, Venezuela crudes outperform gel-type ones made from Chinese, Indian, Kuwaiti, Russian, and South Korean sources. Good amounts of asphaltenes together with low wax contents appear to be critical for the production of high quality and durable asphalt binders.
