[0002] Highway construction inspection is a key step in ensuring the quality of highway projects, and it runs through the entire process before, during, and after construction. Its purpose is to ensure the strength, stability, durability, and safety of the highway by inspecting the quality of raw materials, various construction processes, and finished products.
