Gilsonite

It uses as bitumen binder modifier with various properties. The combine effect of bitumen and Gilsonite in the same base binder,is obvious.Adding 13~14% gilsonite increase performance of aslt.

Also,viscosity of modified binders by Gilsonite is high. We offer iran Gilsonite for using as alternative modifier to reduce cost of aslt mixture products and compaction in field. Now discovered, aslt cement become harder with Gilsonite. Also it`s thinnes with reactive oil. It`s an oil that contains high content unsaturated fatty acids. By using reactive oil, it would cure or react after using cement to highway. Melting or softening point should be near about 300° F. So it easily softened and blended with petroleum aslt at such temperatures. Adding process should be slow.
