Therefore it is necessary to construct the fundamental and characteristic knowledge of this major according to the idea “ the application and development of highway engineering materials serve as the main thread, and strengthen of the ability of engineering practice serve as the core.” on the basis of the four elements of the material discipline: composition and structure, preparation and synthesis, properties of materials, use performance combined with college characteristics and industry advantage.
They are chemical basic of material preparation, foundation and principle of materials science and engineering, synthesis and processing technology of materials, materials detection and analysis technology, materials properties, computer simulation of materials structure and properties, especially.
