Asphalt additives have good development prospects and warm mix asphalt additives have great potential


Asphalt additive refers to additives used to improve the performance of asphalt and asphalt products. Its varieties include asphalt modifiers, emulsifiers, anti-stripping agents, anti-aging agents, nano-modifiers, etc. Among them, asphalt modifiers are the most important asphalt additives.

Asphalt modifiers refer to natural or synthetic organic or inorganic materials added to asphalt or asphalt mixtures. Substances that can be melted or dispersed in asphalt to improve or enhance the road performance of asphalt, such as adding polymers and resins. , plastics, carbon black, inorganic salts, etc. to improve the mechanical properties of asphalt (strength and toughness, etc.).

According to the different mixing and paving temperatures, asphalt additives can be divided into three categories: hot mix, warm mix and cold mix. Hot mix is ​​the mainstream technology. Asphalt is durable, resistant to moisture damage and thermal cracking, and also has excellent processability and Anti-skid, but hot mix technology has heavy environmental pollution, high energy consumption, and serious aging of asphalt. In the next few years, hot mix asphalt additives will still be the most important asphalt additives. However, in recent years, warm mix asphalt additives (mixed asphalt additives) have been gradually popularized and used. The temperature is generally between 110℃-130℃) is a new type of energy-saving and emission-reducing asphalt mixture. As countries around the world pay more and more attention to environmental protection, warm-mix asphalt additives will become the most promising variety.

Asphalt is mainly used in road paving and maintenance, house construction, airport construction, parking lot construction, bridge construction and other fields, Industrial Research Center The released “Asphalt Additive Industry In-depth Market Research and Investment Strategy Suggestions Report 2021-2025” shows that the current road paving and road maintenance It is the most important application scenario of asphalt. In recent years, as the mileage of global highways has continued to increase, the global demand for asphalt has continued to grow. On the other hand, as the total mileage of highways has increased and the load rate of roads has become higher and higher , the global demand for asphalt in road maintenance is increasing. Driven by the continued growth in demand for asphalt in road paving and road maintenance, the global demand for asphalt additives has shown an overall growth trend. In 2020, the global asphalt additive market size has exceeded 20 billion yuan.

Currently, the major players in the global asphalt additives market include Nouryon (Netherlands), DowDuPont (U.S.), Arkema SA (France), Honeywell International Inc. (U.S.), Evonik Industries (Germany), Huntsman Corporation (U.S.), Kraton Corporation (U.S.) ), Ingevity Corporation (USA) and BASF SE (Germany). As China’s demand for asphalt additives continues to grow, well-known companies such as Sinopec, Li Changrong Group, Jiangsu Jinyang New Material Technology, and Shandong Qiaolong have emerged in China, promoting the development of China and the global asphalt additive industry.

In the future, as developing countries such as China and India not only expand the scale of infrastructure construction, but also as developed countries such as the United States upgrade their original infrastructure, the demand for asphalt in global road construction, road maintenance, airport construction and other fields will continue to grow. , thereby promoting the continued growth of global demand for asphalt additive products. It is expected that the global asphalt additive market will exceed 30 billion yuan in 2025. Especially after the novel coronavirus pneumonia epidemic is over, the global economy and infrastructure construction will accelerate significantly, and global consumer demand for asphalt additives will increase significantly. Overall, the asphalt additive industry has good development prospects in the next few years.
