Gilsonite in Bitumen Blending

Adding Gilsonite to the petroleum bitumen (typically 5 to 10%) will reduce penetration and increase viscosity and increase its softening point.

It also reduces the thermal sensitivity of the bitumen, thus producing good performance at high temperatures.it’s also less damaging to the body.

Before adding Gilsonite, the bitumen is heated and added to the reservoir in turn, then Gilsonite is slowly added to the bitumen whisker, the minimum temperature for doing this is 170 to 175 ° C, if the temperature is less than this Bumping time increases. It takes 2-4 hours to mix 5 to 10 percent Gilsonite with bitumen. If more Gilsonite is needed, more time to mix is needed.

If Gilsonite does not mix slowly, then there is a bullet phenomenon (BALL UP) that will fix this problem by adding specific compounds.

Finally, to make sure the product is desirable, it compares its degree of penetration with the bitumen.

The aggregate strength is determined by selecting the type of aggregate, the type and percentage of the additive, bitumen and rock materials, and is a determinant factor in increasing the bursting strength, the quality of the pavement and the life of the asphalt mixes.

Despite the very low weight of bitumen in asphalt mixtures, an important part of the research in the pavement debate is currently taking place around bitumen.

Gilsonite is known as a bitter reinforcement and hardening agent, and laboratory results have shown that Gilsonite is a  high-performance bitumen.
