Abstract Gilsonite has a wide variety of applications in the industry, including manufacture electrodes, paints and resins, as well production asphalt roof-waterproofing material. ash is determining parameter for its application some industries (e.g., gilsonite with content < 5% used an additive drilling fluids, resins). Due to shortage high grade (low ash) reserves, aim this study develop p...

Hot mix asphalt has various benefits such as good workability and durability. It is one of the most general materials used mixtures in road pavements. Asphalt binders can be improved by modifying them with additives. Gilsonite a natural hydrocarbon which may an additive to hot asphalt. binder modifier (wet process) mixture (dry improve properties mix. provides option rheological properties, sta...

The effectiveness of natural Gilsonite on the performance properties modified bitumens was studied. Three samples having different ratios that are 6%, 8% and 10% by weight base bitumen which PG 64-16 grade were prepared. physical storage stabilities four investigated means conventional tests. short-term long-term aging processes conducted with rolling thin oven pressure vessel tests, respective...
