Tar bitumen

Types of Tar Bitumen

Tar bitumen, also known as bitumen, is a thick, black, and sticky liquid derived from crude oil. It is commonly used for paving roads and roofing. There are different types of tar bitumen, which include the following:

• Natural asphalt

  Natural asphalt is a tar bitumen that is found in a semi-solid state. It is located at places like the pitch lake in Trinidad and Tobago. This pitch lake is a notable site where natural asphalt is found. Natural asphalt can also be found in deposits. These deposits are called rock asphalt or surface asphalt. They are found at locations where crude oil seeps to the surface and then evaporates. Eventually, a residue of asphalt is left behind.

• Raffinate asphalt

  Raffinate asphalt is a type of asphalt that is produced during the process of deasphalting. During this process, asphalts with high molecular weights are removed from heavy crude oils. The removed asphalts are called the maleate fraction, and the raffinate asphalt is the leftover fraction. The deasphalting process is done using a solvent. The asphalts that are left behind have lower molecular weights and are more suitable for making pavements.

• Vacuum residual asphalt

  This asphalt is obtained from a vacuum distillation process. It is a thick and viscous liquid that cannot flow freely. This process separates the lighter oil fractions from the heavier ones in crude oil. The heavier fractions are further processed to produce other lighter oil products. The leftover fractions are called vacuum residuals, and they are used to produce commercial-grade tar bitumen.

• Bitumen

  Bitumen is a sticky, black, viscous liquid produced from the refining of crude oil. It has varying grades and types, which are determined by penetration and viscosity. The penetration test measures how soft or hard the bitumen is, while viscosity measures the bitumen's thickness or ability to flow. The two tests are used to classify the bitumen into different grades. For instance, the penetration grade bitumen is classified into 10/20, 30/40, 40/50, and so on. The numbers represent the bitumen's hardness and softness. The higher the number, the harder the bitumen, and vice versa.

Features and Functions of Tar Bitumen

Tar bitumen has many applications in the construction industry. Its features and functions include:

• Waterproofing

  Tar is known to be an effective waterproofing material. Its ability to repel water makes it ideal for protecting surfaces from water damage. Tar is used to create waterproof membranes used in foundations, roofs, and decks. This helps to prevent moisture infiltration and extends the durability of structures.

• Adhesive

  Due to its excellent bonding capabilities, bitumen tar is used as an adhesive in construction. It is used in the application of roofing materials and creates a lasting bond that resists water.

• Sealing

  Tar bitumen is used for sealing cracks in asphalt pavements. It is also used to seal roof membranes, ensuring that water cannot penetrate through cracks or joints.

• Roofing

  Tar-based roofing materials, such as built-up roofs and modified bitumen systems, offer long-lasting protection for flat and low-slope roofs. They provide an effective barrier against water, wind, and UV radiation.

• Road construction and maintenance

  Tar is an important material in road construction and maintenance. It is used to produce asphalt concrete, a mixture of aggregates, tar, and other additives. This creates durable and smooth roads. Tar bitumen is also used in sealcoating, which protects pavements from water, oil, sun, and other chemicals that can deteriorate the pavement. It is also used to fill cracks in asphalt pavements to prevent further deterioration.

• Durability and Longevity

  Tar bitumen is durable and long-lasting. When properly maintained, it can last for decades. It is resistant to UV radiation, heat, and cold temperatures. This material is recyclable, and when a road made of tar bitumen is repaved, the tar bitumen used does not lose its properties.

• Ease of Application

  Tar bitumen is easy to apply. It can be melted and poured onto areas that need to be repaired. This makes it a popular choice for roofs and pavement repairs.

• Cost-Effectiveness

  Tar bitumen is affordable. The initial cost of materials and repairs is low. Even maintenance and repairs are also affordable since minor issues can be fixed without a lot of money.

Scenarios of tar bitumen

Tar bitumen is an essential construction material with a wide range of applications across industries. Its usage scenarios include:

• Road Construction and Maintenance

  Bitumen tar is used in constructing asphalt concrete roads, parking lots, driveways, and airport runways. It is also used in surface dressing to improve road quality and prolong its lifespan.

• Roofing Applications

  Tar bitumen is used in built-up roofs, modified bitumen roofs, and asphalts. It is ideal for low-sloped roofs in commercial and industrial settings.

• Infrastructure and Pavement Construction

  Tar bitumen is used in constructing and maintaining roads, highways, parking lots, airport runways, and pathways. It is preferred due to its durability, weather resistance, and ability to withstand heavy traffic. Bitumen is also used in surface dressing and sealcoating to enhance the lifespan of roads and improve traction.

• Waterproofing and Damp-Proofing

  Tar bitumen is widely used in waterproofing materials like bituminous membranes and coatings. These materials create a waterproof barrier that protects structures from water damage.

• Bitumen in Construction and Roofing

  Tar bitumen is used in road construction, roofing, and waterproofing applications. It is valued for its adhesive properties, UV resistance, and ability to create a durable and weather-resistant surface.

• Industrial Applications

  Tar bitumen is used in the manufacturing of products like adhesives, sealants, paints, and coatings. Its viscous nature and waterproof properties make it an ideal ingredient in these products.

• Mining and Drilling

  Bitumen is used in the mining and drilling industry as a binding agent for ore and a lubricant for drilling tools.

• Specialized Applications

  Tar bitumen is used for various specialized applications, including producing roofing felt, artist's pitch, and anatomical models. Its waterproof properties and adhesive nature make it suitable for these applications.

• Tar Bitumen in Agriculture

  Bitumen is used in the agricultural sector to manufacture fencing poles, irrigation pipes, and containers. Its water-resistant properties and durability make it suitable for these applications.

How to Choose Tar Bitumen

• Bitumen's Purpose:

  Understanding why a particular type of tar bitumen is needed is essential. Each use demands different characteristics from the bitumen. For instance, a specific kind of bitumen is required to make roads, while roofing requires another.

• Studying the Specifications:

  It is essential to check out the bitumen's technical details. This includes the penetration grade, softness point, and viscosity. The bitumen is more suitable for specific applications when the characteristics match the intended use.

• Ascertaining the Source:

  The credibility of the supplier goes a long way in assuring the quality of the delivered product. It is advisable to choose a trustworthy supplier with a good track record. Consider reading reviews and, if possible, visiting the supplier's facility.

• Environmental Considerations:

  It is essential to consider the environmental effect of bitumen production. It is advisable to choose suppliers with sustainable practices. This minimizes the negative effect of bitumen on the ecosystem.

• Pricing:

  While the price of the bitumen is not the primary consideration, it is essential to choose a bitumen that falls within budget. However, it is equally important not to sacrifice quality for price. A good balance between the two is recommended.

• Customer Support:

  Business owners should look for suppliers with excellent customer support. This is because, at some point, they will need to consult the support team to solve issues or get more information. Ascertaining that the supplier has a solid support team is essential before purchasing.

• Delivery and Logistics:

  When buying tar bitumen in bulk, considering the logistics is essential. The vendor should be able to deliver the product on time and at the right place. So, business owners should consider the vendor's delivery capabilities before purchasing.
