Gilsonite using as additive in paving on special location of roads

Gilsonite, being a hydrocarbon, is somewhat soluble in hydrocarbon solvents. It is more soluble in kerosene and naphtha than it is in crude oil. The effect of crude oil on set cement containing gilsonite is negligible beyond the dissolution of exposed gilsonite particles.Gilsonite has a melting point of 385°f. Some softening occurs above 24('f and particles may tend to fuse together. Because of the temperature reduction during circulation, gilsonite can be used in wells having a static bottom-hole temperature of 300°f and slightly higher.Gilsonite is found in nearly straight, vertical veins across an area approximately 100 kilometers long and 50 kilometers wide. Gilsonite was formed by a unique geologic event millions of years ago that caused a proto-petroleum deposit forming at that time to fill large surface cracks, later solidifying into the pure resinous rock mined today. Gilsonite is hand-mined in underground shafts using pneumatic jack hammers. We separate Gilsonite by temperature grade, dry and screen it, size it to customer specifications, and submit it to extensive quality control procedures before shipping to over 80 countries worldwide
