Gilsonite Resin - A Modifier for High Stability Pavements

The use of modifiers to improve the performance of bituminous road paving materials is increasing worldwide. Gilsonite resin is used by asphalt producers, road paving engineers and paving contractors who are concerned with PG specifications, high performance and cost effectiveness. Gilsonite, long known as a bitumen reinforcer and hardening agent, also offers a unique combination of high performance and economy for high stress paving applications.

The main benefit of Gilsonite is in producing road pavement mixes of higher stability than conventional ones. Gilsonite, a unique, natural hydrocarbon, high in asphaltenes and nitrogen compounds, is a granular solid that is fully compatible with bitumen. It can be melted into hot bitumen, or it can be added during hot mix manufacture. In either case, Gilsonite dissolves easily in bitumen and achieves a uniform, easily workable hot mix.

The stability of Gilsonite-fortified pavements makes them more resistant to deformation problems, such as rutting and shoving, and increases the pavement's load carrying ability. In addition, laboratory test and field results show that increased deformation resistance can be obtained while the pavement retains much of its original ductility and ability to resist low temperature cracking. Other positive benefits include increased resistance to water stripping and aging.
