Highway engineering (Unit-4) Pavement design

The unit covers following points Types of Pavement: - Flexible Pavement: Comprises multiple layers of materials, including asphalt concrete, designed to flex under traffic loads. - Rigid Pavement: Constructed using a single layer of reinforced or unreinforced concrete, providing rigid support to traffic loads. Design of Pavement: - Structural Design: Determining the thickness and composition of pavement layers to withstand anticipated traffic loads. - Material Selection: Choosing appropriate materials based on factors such as climate, soil conditions, and traffic volume. - Drainage Design: Incorporating proper drainage systems to prevent water accumulation and ensure pavement durability. - Environmental Considerations: Addressing sustainability and environmental impact concerns in pavement design and construction.
