Benefiting from the demand for downstream kilometers and bridge construction, the asphalt concrete industry shows a growth trend

Asphalt concrete, also known as asphalt concrete, is a road asphalt material produced from gravel, stone chips, mineral powder, crushed gravel, etc. according to a certain proportion. The resulting mixture is then stirred under strictly controlled conditions. At present, most domestic road surfaces are made of cement, but cement concrete has a long production cycle, difficult maintenance, will cause great wear and tear on tires, and has disadvantages such as high noise. Compared with cement concrete, asphalt concrete has more advantages. With the advancement of domestic asphalt production technology and residents’ requirements for driving comfort, asphalt concrete has been used in highways, bridges and other fields, and market demand continues to rise.

The upstream raw materials of asphalt concrete are mainly sand and gravel aggregates and petroleum asphalt. my country’s sand and gravel aggregate industry is relatively mature and its output is stable. In 2020, my country’s sand and gravel aggregate output was 1.91 million tons. Petroleum asphalt is one of the indispensable materials for high-speed road construction. In the past five years, my country’s petroleum asphalt production has shown a continuous growth trend, reaching about 63 million tons in 2020. The output of upstream raw materials continues to grow, which is beneficial to asphalt concrete production and promotes the development of the industry.

According to the “China Asphalt Concrete Industry Market In-depth Research and Development Prospects Forecast Report 2022-2027” released by the Industrial Research Center, asphalt Concrete is mainly used in highway construction. In 2020, the total mileage of highways in our country was 5.2 million kilometers, an increase of 190,000 kilometers over the previous year. my country’s construction mileage continues to grow, and the market demand for asphalt concrete increases accordingly. In the past five years, my country’s asphalt concrete production has continued to rise, reaching 320 million tons in 2016 and growing to 470 million tons in 2020. As production increases and demand grows, my country’s asphalt concrete market continues to grow, from 156.6 billion yuan in 2016 to 255 billion yuan in 2020.

Domestically, East China is the main production area of ​​asphalt concrete, with Shandong Province, Guangdong Province, Hebei Province, Fujian Province, Henan Province and other regions having higher output. In addition to its application in highway construction, asphalt concrete is in high demand in bridge construction. In 2019, there were 870,000 highway bridges in my country, with a total length of 60.63 million meters. In 2020, the number of highway bridges in my country was 910,000, with a total length of 66.3 million meters. rice. It can be seen from this that the number and length of highway bridges in our country are showing a growth trend, which will also drive the demand for asphalt concrete to rise, which is beneficial to the development of the industry.

Industry analysts said that asphalt concrete is mainly used for highway bridges and highway construction needs. As my country’s infrastructure projects are still advancing, bridges The continuous growth in quantity and highway mileage has driven the asphalt concrete market demand to continue to rise, and the industry has good development prospects. The production process of asphalt concrete is relatively mature, and the supply of raw materials is sufficient. At present, the output is mainly driven by downstream industries, and due to the transportation radius, the production areas are mostly demand areas. The production and demand of green concrete are relatively high in East China.
