Gilsonite is a natural asphalt-like material that is often used as a modifier or additive in bitumen mixtures. The specific mix ratio of Gilsonite with bitumen can vary depending on the desired properties of the final asphalt mix and the specifications provided by the relevant authorities. However, there is no universally recommended mix ratio, as it depends on various factors such as the type of bitumen, desired performance characteristics, and project requirements.

Typically, Gilsonite is added to bitumen mixtures in a percentage or weight ratio ranging from 10% to 30% of the total bitumen weight. The specific ratio within this range will depend on factors such as climate conditions, traffic loads, desired flexibility, and the specific application of the asphalt mix.

The mix ratio of bitumen with Gilsonite can vary depending on the specific application and desired characteristics of the mixture. Gilsonite is a natural asphalt/bitumen modifier that is commonly used to improve the performance of bitumen-based materials.

Typically, the mix ratio of bitumen to Gilsonite can range from 90:10 to 70:30 by weight. This means that for every 100 parts of bitumen, you would add 10 to 30 parts of Gilsonite. The exact ratio will depend on factors such as the desired stiffness, temperature susceptibility, and other performance requirements.

Here’s an example to illustrate the calculation:

The specific ratio may vary depending on the desired properties and application of the final product. However, a common ratio for mixing Gilsonite with bitumen 60/70 is approximately 3-5% Gilsonite to 95-97% bitumen.

Let’s assume you have 1000 kilograms of bitumen 60/70 and you want to mix it with Gilsonite at a ratio of 4% (by weight). To calculate the amount of Gilsonite needed:

Gilsonite weight = 1000 kg (bitumen weight) x 4% (Gilsonite ratio) = 1000 kg x 0.04 = 40 kg

So, you would need to mix 40 kilograms of Gilsonite with 1000 kilograms of bitumen 60/70 to achieve a 4% ratio.

It’s important to note that the optimal mix ratio can vary based on the specific properties of the bitumen and Natural Asphalt being used, as well as the climate conditions and intended application. It is recommended to consult the manufacturer’s guidelines or seek expert advice to determine the most suitable mix ratio for your specific project.
