The asphalt mixing plant can produce all kinds of colorful asphalt. The most basic value of these asphalts is paving. Any road can be paved, regardless of national roads, provincial roads, and rural roads. The main problem is the ratio of raw materials used. It is very extensive, and it can also make its own contribution to the airport. For example, the airstrip, especially the runway on the aircraft carrier, has a short distance and a strong load-bearing capacity, so it is most suitable to use asphalt. The cost will increase a lot, and it is better to use asphalt pavement. It can also be used for port construction.
