<Road Subgrade and Pavement Engineering> is a core course of highway engineering. The course is divided into two parts: basic and engineering: the basic part includes traffic, environment, materials, drainage, subgrade stress and service capacity, pavement stress and service capacity; the engineering part includes roadbed design, asphalt pavement design, cement pavement design, and subgrade pavement construction. Through this course, learners should master the basic concepts of subgrade and pavement engineering (know what it is), be able to design subgrade and pavement in accordance with Chinese engineering specifications (learn how to design) and understand common construction methods.
