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.

Abstract: A modified sulfur cement comprising the polymeric reaction product of elemental sulfur and a cyclopentadiene oligomer containing reactant.Cement compositions can be formulated by blending an aggregate material with the modified sulfur cement.

Abstract: Spent asphaltic concrete is recycled by crushing, heating and admixing with sulfur at elevated temperature.

Abstract: A composite structural material is prepared by admixing (1) sulfur plasticized by reaction with dicyclopentadiene, or dicyclopentadiene and styrene, (2) asbestos fibers wetted with dipentene and (3) silica flour, maintaining the mixture at about 120 to 150.degree. C for about 0.5 to 5 minutes and casting the resulting product under a pressure of about 500 to 1500 psi. Additional strength is obtained by curing at elevated temperature prior to casting.
