Pavement Design and Management

Pavement Design and Management is a specialized area within Civil Engineering that focuses on the entire lifecycle of paved surfaces, such as roads, highways, and airport runways. The design phase involves the structural analysis and selection of materials—like asphalt or concrete—and the determination of layer thicknesses to withstand anticipated traffic loads and environmental conditions for a specified service life. The management aspect extends beyond initial construction, incorporating systematic data collection to monitor pavement condition, predict future deterioration, and strategically plan maintenance and rehabilitation activities to ensure safety, preserve the infrastructure investment, and minimize long-term costs.
