This lecture covers the Swiss method of road pavement design, based on the American H.O. method, focusing on fatigue design and considering factors like traffic loads, pavement lifespan, and material properties. The lecture also discusses the importance of homogeneity in pavement design, the classification of soil types for foundation design, and the calculation of the structural number for pavement strength. The instructor explains how to determine the pavement structure based on material properties and thickness, emphasizing the significance of choosing the right materials for optimal pavement performance.
