Asphalt Mix with Gilsonite

Asphalt Mix with Gilsonite in UAE/Dubai: and other asphaltites help improve the performance of asphalt mixes. Paving mixes that use gilsonite reach higher performance grades (PG) and can be blended into asphalt without needing high-shear milling, unlike some other modifiers. It can either replace or complement the use of SBS (styrene-butadiene-styrene) polymers in asphalt mixes. Gilsonite-modified asphalts provide better stability, reduce deformation, lower temperature sensitivity, and increase resistance to water damage compared to non-modified asphalts. However, one challenge of using gilsonite as a modifier is that it’s a solid, making it harder to handle and mix with thick bitumen.

Asphalt Mix Additives

Many polymers are using as additives in asphalt mixesed, and gilsonite is one of them. For example, copolymers made from styrene and butadiene or isoprene work well because they dissolve easily in bitumen. These modified asphalt mixes also have good flow and flexibility.

How Gilsonite Works in Asphalt Mixes

Dry Blending: It is ground into a fine powder and mixed with hot aggregate before adding liquid asphalt. This ensures the gilsonite spreads evenly, which strengthens the overall mix.
Wet Blending: This product can also be dissolved directly into the heated asfalt binder before mixing with the aggregate. This method creates a uniform and durable blend.

Benefits of Gilsonite in Asphalt Mixes

Improved Rut Resistance: Natural asphalt significantly strengthens the mix, which helps it resist deformation under heavy traffic. As a result, it enhances the overall durability of the pavement. Moreover, this increased strength allows the asphalt to maintain its integrity over time, even in demanding conditions. Consequently, roads treated with natural asphalt can better withstand the stresses of heavy loads and prolonged use.
Increased Durability: It hardens and stiffens the asphalt, making it better at resisting cracking, weathering, and oxidation.
Slower Aging: Natural bitumen helps slow down the aging of the asphalt binder, which allows the pavement to stay flexible longer.
Better Temperature Performance: It helps the asfalt withstand extreme temperatures, both hot and cold, making it suitable for various climates.

Conclusion

In summary, this product makes asphalt mixes stronger, more resistant to wear, and improves their long-term performance, even in challenging conditions.
