Gilsonite and modified Gilsonite are adding directly at the production site of the asphalt and bitumen mixing plant. To use asphalt in road construction in cold weather just use our gilsonite and no need to use any special bitumen! Just bitumen 50-70 is more than enough! Gilsonite as bitumen binder modifer Gilsonite is used as a bitumen binder modifier with various properties of binder that is modified only by Gilsonite are common, we investigate the effect of combining bitumen and Gilsonite in the same base binder. Adding 13~14% gilsonite increase performance of asphalt. Also, the viscosity of modified binders by Gilsonite is always high. We are suggesting iran Gilsonite can be used as an alternative modifier to reduce the cost of asphalt mixture production and compaction in the field.
