Bitumen oil, also known as tar sands or oil sands, is a type of unconventional petroleum deposit. It is a mixture of bitumen, a heavy, viscous form of crude oil, sand, clay, and water. Bitumen oil is found in large deposits primarily in Canada, Venezuela, and smaller quantities in several other countries. Extracting process The […]

Penetration test for bitumen Standard Test Method for Penetration of Bituminous Materials.This standard is issued under the fixed designation ASTM D5 and the number following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A […]
Political Intervention in Commodity Markets From the 1980s to the early 2000s, global economic policy leaned strongly toward deregulation and market liberalisation. Since the Energy Market Outlook 2023 financial crisis, and more visibly during 2020–2022, the trend has shifted back toward government intervention Energy Market Outlook 2023 and regulation, especially in commodity and energy markets.

What is viscosity grade bitumen? Viscosity is defined as the inverse of fluidity. Therefore, the viscosity determines the fluid properties of the bitumen material. Viscosity is a general term for consistency and is a measure of resistance to flow. Bitumen is produced and graded with a different viscosity grade than other types of bitumen. This […]
Revolutionizing Greenhouse Gas Sequestration with Asphalt-Derived Sorbents Researchers at Rice University have introduced a new Gilsonite-based filter that captures carbon dioxide (CO₂) directly at natural gas wellheads. The innovation represents a major step in greenhouse gas sequestration and efficient energy production. The study, led by Professor James Tour, found that Gilsonite asphalt becomes a powerful […]
Gilsonite in self heating asphalt repair system Cracks in asphalt are a common sight, but a pain Gilsonite in self repair asphalt. It is expensive and because the roads need to be closed down for construction, traffic jams occur. Researchers at polymer institute of research and development in Turkey are working on a solution by […]
Gilsonite exported in high quantity since 2013 Due increase of crude price and then bitumen price Chinese started to buy Gilsonite from Iran again in high volume.Normally they are buying in raw form and pulverizing in very fine particle size to save some cost and control the quality. On September and October compare other months since 2013 till today,Iranian […]
Bitumen project in Africa Bitumen project moving slowly due economic issue and rainy season in Africa.The pressure on road paving is increasing for a variety of reasons including climate change and rising average ambient air temperatures. Roads are not designed to withstand this, leading to early-life surface rutting and deformation that has to be repaired more […]
Gilsonite: A Breakthrough Material for Lithium Batteries Researchers at Rice University, led by chemist James Tour, developed an anode made from porous carbon derived from Gilsonite. This unique material demonstrated outstanding stability over 500 charge-discharge cycles. With a current density of 20 mA/cm², the Gilsonite-based anode shows promise for high-power, rapid-charge battery applications—charging fully in […]
Modified asphalt refers to an enhanced asphalt binder created by blending traditional asphalt with modifiers such as rubber, resin, high-molecular polymers, natural asphalt, ground rubber powder, or other external materials. These additives aim to improve the physical and mechanical performance of asphalt mixtures, particularly for use in road construction and infrastructure projects. What Is an […]
