Editor’s Note: While much of the background in this piece is familiar to the AsphaltPro audience, Harshada Dive’s insight offers forward-looking ideas for readers.
In recent years, the bitumen industry has witnessed significant growth and evolution. Bitumen plays an important role in the construction and infrastructure sectors and, according to Allied Market Research, the global bitumen market is expected to exhibit a considerable CAGR of 3.5% throughout the forecast timeframe.
Readers will be familiar with the process of bitumen extraction, during which impurities, such as calcium, Sulphur, oxygen and iron, are removed. In the industrial process of bitumen production, crude oil is first distilled at 200°C and then further heated to 300°C to transform it into vapor. This process extracts various lighter components from crude oil, such as gasoline, petrol, diesel, lubricating oils and waxes, leaving bitumen as the final product. To obtain bitumen by vacuum distillation, the remaining crude oil is poured into separate distillation columns, which is called fractional distillation. While bitumen can be produced in factories, it also exists naturally in oil sands, bituminous rocks and lakes. It should be purified for practical use.
The different types of bitumen depend on various specifications such as constituents, uses and viscosity. Some types of bitumen commonly employed for constructing flexible pavements are paving grade, emulsion and polymer-modified.
- Paving grade bitumen:
Paving-grade bitumen is derived from the distillation of crude petroleum and is commonly used in surface and binder applications. Bitumen is typically semi-solid, highly viscous and adhesive at regular temperatures. However, when it is heated, it becomes soft and liquid, and its viscosity decreases as the temperature rises.
- Bitumen emulsion:
Bitumen emulsion is prepared by the dispersion of bitumen into small droplets suspended in water, which is facilitated by the use of an appropriate emulsifier.
- Polymer-modified bitumen:
Polymer-modified bitumen can be used in the construction of tank foundations containing different fluids. Moreover, it is used to prevent the degradation of railway tracks and roads and to absorb noise and vibrations.
Bitumen Market Trends
The need for bitumen is constantly increasing due to the upsurge in road construction projects. Most of the bitumen used is transformed into asphalt for road construction. Asphalt consists of crushed rocks and bitumen. Bitumen acts as a binder that ensures the durability of asphalt. Asphalt roads can be adapted according to different climatic conditions and operational requirements by using different types of bitumen or mixtures. In addition, asphalt can be used in airport runways, parking structures and port work areas.
The infrastructure activities in the Asia-Pacific region, especially in the transport sector, are growing rapidly because of urban modernization and the emphasis placed on developing secondary sectors in these countries. Moreover, an increase in economic growth stimulates the financing of infrastructure in consumer sectors, including transport and manufacturing which are essential for providing raw materials to produce consumer goods.
According to a survey by thе U.S. Census Bureau, public expenditure on infrastructure development, еspеcially on roads and highways, has bееn on thе risе in thе Unitеd Statеs for decades. Additionally, in 2021, the China State Construction Engineering Corporation (CSCEC) signеd an agrееmеnt to build about 2,797.41 miles (4,502 kilometers) of nеw roads, which was morе than thе prеvious year’s 2,601.06 miles (4,186 km). These developments reinforce the positive development of the bitumen market.
Furthеrmorе, India has allocated $1.4 billion for infrastructure investment undеr thе National Infrastructurе Pipеlinе (NIP), with 19% of this budgеt going to roads and highways. Thе country’s approved budgеt includеs plans for thе dеvеlopmеnt of various industrial corridors, which includеs Amritsar-Kolkata Industrial Corridor, Dеlhi-Mumbai Industrial Corridor, Vizag-Chеnnai Industrial Corridor, Bеngaluru-Mumbai Industrial Corridor, and Bеngaluru-Chеnnai Industrial Corridor. It is еxpеctеd that thеsе projеcts will be complеtеd by March 2025 and that thе dеmand for bitumеn will incrеasе in thе upcoming yеars. Owing to thеsе rеcеnt dеvеlopmеnts, it’s еxpеctеd that thе global bitumеn markеt will grow ovеr thе projеctеd pеriod.
Some of the major players in the industry, including Royal Dutch Shell PLC, China Petroleum & Chemical Corporation, Hindustan Petroleum Corporation Limited, Asphalt & Bitumen West Co., and TotalEnergies, are engaging in the development of innovative technologies and introducing new products, strategies and collaborative alliances. For instance, in November 2022, NYNAS AB launched Nypol RE, a novel polymer-modified bitumen. This innovative product incorporates biogenic materials to enhance its durability while minimizing its impact on the environment, which distinguishes it from bitumen alternatives.
In another key development, ExxonMobil resumed the operation of its bitumen production plant in Singapore in May 2021. The production plant is capable of producing approximately 100,000 to 120,000 tons of bitumen per month.
Furthermore, in March 2019, Royal Dutch Shell launched FreshAir, a sustainable asphalt product. The main objective of this initiative is to mitigate any lingering environmental impact caused by the emissions generated in the construction of asphalt roads.
To summarize, thе global bitumеn industry is growing at an accеlеrating pacе, drivеn by thе incrеasing dеmand for road construction and maintеnancе, as wеll as tеchnological innovation. Furthеrmorе, thе construction sеctor is dеvеloping rapidly and is еxpеctеd to progress, with a robust focus on advancеd innovation.
