natural bitumen

Natural bitumen, otherwise referred to as asphalt or tar, is a rare material with an incredible history. Dating back centuries, it has been put to use for constructing buildings, orchestrating adhesives, and even creating waterproofing agents. This natural mineral is a kind of petroleum that is sourced from reservoirs across the globe. Despite its ubiquity in various projects, many individuals are unaware of what natural bitumen is and how it comes into being. This article will expound upon the characteristics and properties of bitumen, such as what it is composed of, its practical advantages, and the diverse forms of activity it is used for.

What Natural Bitumen Is

Millions of years in the making, natural bitumen or asphalt is a semi-solid or solid form of petroleum found in the earth. It is composed of a complex amalgamation of hydrocarbons, consisting of asphaltenes (which is used in asphalt paving process)  and resins, as well as containing compounds of sulfur and nitrogen.

Often formed through the decomposition of organic matter, like dead plants and animals, this heavy black substance can usually be found in areas of geological movement such as those areas subject to volcanic eruptions or tectonic shifts.

For centuries, mankind has been exploiting the many uses of bitumen. Its waterproofing capabilities, its application in road infrastructure, and its energy-producing properties, all account for its many advantages. Even in modern times, it still plays a significant role, as a heat-resistant material in asphalt production for roads and roof tiles, and in various industrial applications.

Natural Bitumen Price

The price of natural bitumen can be incredibly varied, depending on numerous factors. These include supply and demand which is heavily influenced by the limitations of available supplies; location which takes into account the transportation and distribution costs; a quality which dictates the caliber of the product consumed; extraction and production costs which reflect the effort to acquire the resource; and finally, market competition which drives the competing prices.

With all these variables, it is practically impossible to provide a precise price tag for bitumen. Fortunately, you can still find indicative costs by looking into local suppliers or industry reports. To ascertain how much natural bitumen will cost, you first need to evaluate the current demand and supply. From there, investigate the location of the source, analyze the quality of the commodity, calculate the extraction and production costs, and inspect the level of competition in the market for natural bitumen.

What’s the Difference Between Bitumen and Asphalt?

Asphalt and bitumen may sound similar but they are two distinct materials commonly used in the construction industry. Bitumen, also known as asphalt binder or asphalt cement, is a tacky, black, semi-solid form of petroleum. It is a highly viscous and malleable substance derived from crude oil through an intensive refining process. 

As a binder, Bitumen forms the “glue” that holds asphalt together. It is especially useful in the construction of roads, pavements, and waterproofing applications; providing durability, flexibility, and resistance to deterioration and aging. 

On the other hand, asphalt is a mixture of bitumen and aggregates such as sand, gravel, and crushed stone. It is used as a surfacing material for roads, parking lots, driveways, and many other paved surfaces.

Asphalt is usually produced in special asphalt plants, where bitumen is mixed with the said aggregates at high temperatures to create a homogeneous product. The resulting asphalt blend is then rolled and compacted to form a tough and resilient pavement.

Types of Natural Bitumen

There are several different types of bitumen, each with its unique characteristics. Some of the most common types include:


Gilsonite is a naturally occurring hydrocarbon, found in regions of Utah and Colorado and beyond. Its defining feature is its remarkably high melting point, making it an integral component for many industrial applications, from asphalt pavement to roofing materials and beyond. Its unique properties thus render it a valuable element, highly regarded and sought after for its properties to facilitate various industrial projects.
