Bitumen is an oil based substance. It is a semi-solid hydrocarbon product produced by removing the lighter fractions (such as liquid petroleum gas, petrol and diesel) from heavy crude oil during the refining process. As such, it is correctly known as refined bitumen. In North America, bitumen is commonly known as “asphalt cement” or “asphalt”. While elsewhere, “asphalt” is the term used for a mixture of small stones, sand, filler and bitumen, which is used as a road paving material. The asphalt mixture contains approximately 5% bitumen. At ambient temperatures bitumen is a stable, semi-solid substance.

Bitumen is classified by the depth to which a standard needle will penetrate under specified test conditions. This “pen” test classification is used to indicate the hardness of bitumen, lower penetration indicating a harder bitumen. Specifications for penetration graded bitumen normally state the penetration range for a grade, e.g. 60/70. Other tests are used to classify the bitumen for specification purposes, such as softening point, solubility, flash point etc.

Grades available: 60/70 and 80/100.

Aggbind Exp 75

Aggbind Exp 75 is a specially formulated bitumen adhesion agent used to provide optimum adhesion in the presence of moisture or advance the adhesion of aggregates that have an inferior affinity for bitumen.

Using Aggbind Exp 75 greatly improves the resistance to stripping of bitumen seals even when using aggregates that include acidic or quartz rich materials such as quartz, quartzite, granite and some river gravels. These aggregates are generally high in silica content and present a higher risk of stripping.

Other benefits using Aggbind Exp 75 are its pourability, effectiveness, heat stability, low settlement and cost performance.

Asphalt Release Agents

Asphalt Release Agents are made from completely natural raw materials used where good adherence and effective release is required particularly when used in environmentally sensitive areas.

Bitumen Paints

Bitumen paints are used in construction and industrial sealing applications.

When Gasoline was so cheap it was worthless

During the early days of Standard Oil (this was before cars became popular), kerosene was the name of the game. Gasoline, a by-product of petroleum distillation to produce kerosene, didn’t have much demand. It was a cheap product used to treat lice and a solvent to remove grease stains from clothing … In fact, gas was so cheap that oil companies used to dump it in rivers!
