natural asphalt is mineral bitumen or gilsonite which is mixing with bitumen to increase volume and decrease of bitumen
Gilsoniteis a naturally occurring hydrocarbon, mined in Kermanshah, Iran. With apurity in excess of 99% it is high in asphaltenes (70%) and compatiblewith all traditional bituminous paving materials. Supplied as a finepowder it is easily added to hot mix asphalt directly into the mixer.Gilsonite dissolves easily in the asphalt to achieve a uniform, easilyworkable asphalt mixture.
Greatly improved water susceptibility characteristics
Greatly improved binder/aggregate adhesion
Increased mixture stiffness and binder viscosity
Improved anti-rutting performance
Improved pavement load carrying ability
Retention of original ductility
Increased resistance to pavement deformation
Ability to resist low temperature cracking
Positivebenefits include increased resistance to water stripping and ageing.Gilsonite produces road pavement mixes of higher stability thanconventional ones.
The stability of Gilsonite-fortified pavementsmakes them more resistant to deformation problems, such as rutting andshoving, and increases the pavement's load carrying ability. Inaddition, laboratory tests and field results show that increaseddeformation resistance can be obtained while the pavement retains muchof its original ductility and ability to resist low temperaturecracking.
