Abstract
Solid, low-cost paving binder prepared by admixing sulfur, paving grade asphalt (AC) asphalt, and a siliceous filler such as fly ash and silica material, and solidifying the product into preferably flaked, pellet or pastille forms. Carbon black is another possible ingredient of the paving binder. The solid paving binder has non-sick non-flow properties within a wide range of ambient temperatures, and it can be stored solid for subsequent use in paving applications. Properties such as the color, radiation-resistance, and odor of the paving binder can be controlled in the manufacturing process.
