Design of Highway Pavements topics include: Highway pavements design, flexible pavement components and performance, flexible pavement design method, rigid pavements and their functions, rigid pavements stresses and design methods.
When designing highway pavements, you can consider the following factors: Traffic: The volume and composition of traffic Vehicle axles: Heavier axles can damage pavements more than lighter ones Thickness: The thickness of the layers Material properties: The properties of the materials used in each layer Wheel loads: The magnitude and number of repetitions of the wheel loads, as well as the contact area between the tire and the road surface Rigidity factor: The ratio of contact pressure to tire pressure
Other highway design factors to consider include: Stiffness, stability, and durability
Design life, which depends on environmental conditions, materials, and maintenance
Requirements for the pavement, such as sufficient thickness, structural strength, and coefficient of friction
Highway pavements are made up of layers of processed materials placed on top of the natural soil sub-grade. Their main purpose is to distribute the loads from vehicles to the sub-grade.
