Analysis of China’s odor-free modified asphalt market status and application prospects in 2023

Clean-odor modified asphalt is a high-performance asphalt that has the dual advantages of clean-odor asphalt and modified asphalt. It is in line with the development trend of high-quality, environmentally friendly and green asphalt industry, and has broad market development prospects in the future.

Odor-free modified asphalt is a new generation of green and environmentally friendly special asphalt products developed on the basis of polymer-modified asphalt. It is mainly obtained by adding odor-cleaning agents to asphalt. The appearance of clean-odor modified asphalt is black liquid, semi-solid or solid, and its shape, color and appearance are the same as ordinary asphalt. Compared with ordinary asphalt, clean-odor modified asphalt has the characteristics of low irritating odor and less harmful gases, and Excellent resistance to cracking, high and low temperature resistance and other properties.

According to the “2023-2027 Net Odor Modified Asphalt Industry Market In-depth Research and Investment Prospect Forecast Analysis Report released by the Industrial Research Center It shows that companies or institutions currently engaged in the research and production of odor-free modified asphalt include Dutch Shell, Sinopec, Dalian Institute, Hunan Zhonghai Shunda, Hunan Transportation Science Research Institute, Henan Jinote Industrial, etc. At present, the odor-free modified asphalt technology independently developed by Sinopec has been successfully applied in Shanghai municipal road construction.

my country is a major country in the production and consumption of asphalt. According to data from the National Bureau of Statistics, in 2022, my country’s asphalt production scale will be 71 million tons. It is expected that asphalt production scale will further expand in 2023, reaching about 76.5 million tons. During use, ordinary asphalt will release a large amount of toxic and harmful smoke and irritating odors when exposed to high temperatures. As environmental protection requirements become increasingly stringent, it will become an inevitable trend for asphalt products to become environmentally friendly and green.

The main components of asphalt flue gas include low-carbon chain hydrocarbons, polycyclic aromatic hydrocarbons, etc., which have adverse effects on the environment and human health. Asphalt flue gas treatment methods include incineration, adsorption, condensation, high-voltage electrostatic collection, low-temperature plasma, etc. Odor-free modified asphalt solves the problem of asphalt flue gas emissions from the root cause. Compared with traditional asphalt flue gas treatment methods, it has the advantages of low cost and good effect.

​Industry analysts said that clean-odor modified asphalt has broad market application prospects. On the one hand, my country’s municipal road construction is currently in a period of rapid development, and the proportion of asphalt pavement will continue to increase. At the same time, the demand for road maintenance is also constantly released, and the market for clean-odor modified asphalt has broad room for promotion. On the other hand, clean-odor modified asphalt is a new generation of green and environmentally friendly materials. With the country vigorously promoting energy conservation, emission reduction and green development strategies, the market demand for clean-odor modified asphalt will continue to be released.

At present, the production and application of odor-free modified asphalt in my country is still in its early stages. In order to achieve long-term sustainable development of the industry, relevant companies still need to increase technical research, optimize product formulas, and formulate product production standards and reasonable production plans. Ensure the smooth application and market development of products.
