ElaborateCourse: Principles and Methods of Pavement Design

精品课程：路面设计原理与方法



Course Introduction  

This course introduces basicprinciples and methods used in pavement design procedure.  The traffic load and climatic conditions whichaffected pavement design process will be discussed. The mechanical propertiesof the most used pavement materials including asphalt, aggregate, cement andsoil will also be introduced. Additionally, the course will teach students howto use the pavement design software (i.e., MEPDG) for the selection of pavementstructure and materials for the preparation of field construction. Themechanism of field pavement distresses and the relevant significant variableswill be discussed, and the very widely technologies utilized in pavementmaintenance will also be elaborated.
