Bitumen is one of the products sold in the Iranian petroleum products market. Solid bitumen has a very wide range of sales and various factors such as the price of raw materials, currency, metal, petroleum products and has a very decisive role in determining the selling price of this product. According to the plan to increase the production of bitumen and equip and modernize the process of refining and production of bitumen, it is hoped that in the coming years, sales of quality bitumen in Iran will increase.
Benefits of Gilsonite in Asphalt Pavement
Scientific research has proven the benefits of using gilsonite in asphalt paving. Studies conducted in 2015 by the Western Regional Superior Pavement Center at the University of Nevada School of Civil and Environmental Engineering in Reno have shown that the use of gilsonite-modified binders has a significant shelf life and increases asphalt pavement.
Gilsonite increases the viscosity of asphalt and thus, unlike other RAP-based modifiers or high-modulus asphalts, makes roads more resistant to deformation and fatigue even at high temperatures. There are many industrial reports that gilsonite-modified asphalt is more than twice as durable as unmodified mixtures. In addition, the high modulus obtained by using gilsonite allows the base and binder layers to be up to 20% thinner while providing the same level of performance that enables us to Use fewer materials. Gilsonite can also act as a cheaper, more efficient spreader in a mixture containing SBS polymers. With a significant increase in the useful life of asphalt pavements and the possibility of reducing the amount of pavement materials required, gilsonite has been shown to be significantly more cost-effective.
This is good news for organizations looking to reduce the long-term maintenance costs of asphalt pavements. Findings from comprehensive experiments have shown that the use of gilsonite-modified binders has resulted in significant improvement in the following cases:
- Tensile strength: The addition of gilsonite has significantly increased the tensile strength in wet conditions and under normal conditions.
- Compressive strength: The use of gilsonite-modified binders has resulted in a significant improvement in compressive strength.
- Rolling strength: The use of gilsonite-modified binders has resulted in a significant increase in the predicted life of the pavement. In all but one case, the addition of gilsonite resulted in a 10-fold increase in pavement life.
Large Scale Production of Gilsonite
Today, natural gilsonite is produced on a large scale in a variety of ways. Gilsonite price depends on many factors. If you want to get specialized information in this field, I recommend that you contact our consultants. Gilsonite sellers in Iran, as the main and major bases for loading and exporting gilsonite, offer very good examples of this product to buyers. In these centers, various analyzes of this product can be done.
