Designing Pavements: Mechanical and Frost Dimensioning

This lecture continues the discussion on designing flexible and semi-rigid pavements using the Swiss method. It covers determining layer thickness based on layer composition, traffic load, soil type, and pavement type. The lecture also delves into the effects of frost on pavements, including structural implications and design considerations. The instructor explains the concept of frost index, the impact of climate conditions, soil sensitivity to frost, and the importance of monitoring frost depth. Practical examples and case studies are used to illustrate the design process and the critical role of frost dimensioning in pavement engineering.
