Abstract
The present invention generally relates to the discovery that a blend of linear and branched amide wax additives can be used to enhance the performance of asphalt binders and asphalt emulsion residues. In particular, high temperature properties of asphalt pavement can be improved while maintaining or improving low temperature properties. The additives also improve workability and lower processing temperatures for asphalt paving (e.g. warm mix) or for roofing. These amide wax additives can reduce the tracking of tack coats, by decreasing binder penetration and forming a non-tacky surface layer.
