A Review on Improving Asphalt Pavement Service Life Using Gilsonite-Modified Bitumen

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, stability, strength rutting resistance moisture sensitivity. This paper examines current research relating use gilsonite (binder mixture). The modified mechanical will reviewed. influence adding individually or combined other additives discussed. Furthermore, assessment environmental economic perspectives studied along some suggestions explored.
