Extended data:

1. Pavement engineering includes pavement base (subbase) construction technology, asphalt pavement construction technology, cement concrete pavement construction technology, pavement waterproof and drainage construction technology, special asphalt concrete pavement construction technology and pavement test and detection technology.

2. In the construction of pavement engineering, we must seize the favorable opportunity. Assault, line length and demolition may affect the construction progress, with a wide working face, large factors influenced by natural conditions, difficult construction management and great damage to the environment, especially when it rains.

3. Just like the relationship between foundation and building subject in construction industry, subgrade belongs to "ground" and "pavement" is the ontology of road. Although the subgrade construction can be filled with stones, it is only rolled, without complicated structure, and the pavement has structural levels.
