The hydrocarbon content is much lower than Ilam and Kermashah and it is just using for foundry.Hydrocarbon content or bitumen content of Gilsonite from Kermanshah and Ilam is first quality of Iran Gilsonite and the purity comming up to 98%. Bitumen 60/70 Road bitumen straight asphalt for pavement , cutback bitumen and emulsion bitumen Bitumen has several types and grade but 70% of usage is in road construction. Road construction has different step and using emulsion, cutback as basement and pavement and then penetration bitumen mixture with aggregates.Penetration bitumen:
