Specifications

Gilsonte, or North American Asphaltum is a natural, resinous hydrocarbon found in the Uintah Basin in northeastern Utah. This natural asphalt is similar to a hard petroleum asphalt and is often called a natural asphalt, asphaltite, uintaite, or asphaltum. Gilsonite is soluble in aromatic and aliphatic solvents, as well as petroleum asphalt. Due to its unique compatibility, gilsonite is frequently used to harden softer petroleum products. Gilsonite in mass is a shiny, black substance similar in appearance to the mineral obsidian. It is brittle and can be easily crushed into a dark brown powder. Gilsonite is found below the earth's surface in vertical veins or seams that are generally between two and six feet in width, but can be as wide as 28 feet. The veins are nearly parallel to each other and are oriented in a northwest to southeast direction. They extend many miles in length and as deep as 1500 feet. The vein will show up on the surface as a thin outcropping and gradually widen as it goes deeper. Due to the narrow mining face, Gilsonite is mined today, much like it was 50 or 100 years ago. The primary difference is that modern miners use pneumatic chipping hammers and mechanical hoists.

Advantages of using Gilsonite in Road Asphalt

  • Gilsonite is used as a performance-enhancing agent for asphalt mixes.
  • Gilsonite-modified paving mixes achieve higher PG grades and incorporate perfectly into the asphalt blend with no need for high shear milling as is the case with many other modifiers.
  • Gilsonite-modified asphalts have higher stability, reduced deformation, reduced temperature susceptibility and increased resistance to water stripping than non-modified asphalts.
  • Gilsonite is also used to make both solvent-based and emulsion pavement sealers with superior appearance and weathering properties.
  • Gilsonite preparing is much economical than Copolymer EVA or SBR.
  • Gilsonite refinery readness way is much easy method.
  • Gilsonite increase refinery softening point since its degree near 60/70 percent and equal with 48 to 54 centigrade ,whereas softening point of gilsonite is 190 to 230 degree centigrade.
  • Gilsonite mixing with the rest parts of asphalt is easy.
