精品课程：Advanced Infrastructure Materials
I. Course Introduction (including teaching goals andrequirements):
Theinfrastructure includes buildings, water treatment and distribution systems,dams, highways, airports and bridges. A basic understanding of the materialselection process, and the behavior of materials, is a fundamental requirementfor all civil and construction engineers performing design, construction, andmaintenance. This course covers the basic and essential topicsrelated to materials used in civil engineering, with a focus on transportationinfrastructure for students in School of Transpiration. The course discussesthe most important groups of materials used in construction, aggregate, cementand asphalt materials, including their properties, manufacturing, evaluation,testing, selection, design, and application.
