Abstract

Sulfur, useable in as an additive to asphalt in the preparation of asphalt binders can be plasticized by addition of carbon and further treated with amyl acetate. This plasticized sulfur can be formed into solid particles and then added to asphalt as either a minority or majority component to create desired paving binder compositions. The solid plasticized sulfur has non-stick non-flow properties within a wide range of ambient temperatures, and it can be stored solid for subsequent use in paving applications.
