Roadways Inspection and Maintenance



Highways and roads are the essential means of transportation between towns, and they play a significant part in integrating economic activity into everyday life. The analysis and design of pavement are key components of this training program on inspection and maintenance of roads, with an emphasis on the creation of connotations in practical design scenarios.
