ABSTRACT

The present work explores the use of dispersants in lowering the viscosity of asphalt mastics. The study includes the use of three different types of dispersants during the mixing of fine aggregates with one specific type of polymer-modified asphalt, namely, Novophalt that has been selected for a case study. The effect of the dispersants on the selection of the mixing temperature is elucidated. A distinction is made between a lubricant and a dispersant by observing the Theological behavior of the aggregate-asphalt systems under different conditions. It is also shown that stearic acid which acts more like a lubricant has the potential to lower compaction temperatures during the paving of roads.
