Natural Bitumen

_{Natural bitumen mainly known as Gilsonite is a natural hydrocarbon, high in Asphaltenes and also has
nitrogen compounds, and fully compatible with bituminous pavement materials. It forms true, stable solutions in bitumen and can be easily incorporated by presolution in the bitumen with agitation or by direct addition during hot mix manufacture.
The main benefit of gilsonite is in producing road pavement mixes of much higher stability than conventional ones. A unique, natural hydrocarbon, high in asphaltenes and nitrogen compounds, 
gilsonite is a granular solid that is fully compatible with bitumen. It can be melted into hot bitumen, or it can be added during hot mix manufacture. In either case, gilsonite dissolves easily in bitumen and requires only a slight increase in mixing time to achieve a uniform, easily workable hot mix.}
