Instructions:

"Explain the process of constructing rigid pavement, focusing on the roles of slabs, joints, and formwork. Describe the materials used, the importance of each component, and how they contribute to the durability and functionality of the pavement."

Guidelines:

1. Introduction: Briefly introduce what rigid pavement is and its primary components.
2. Slabs: Explain the purpose of slabs in rigid pavement, how they are placed, and the materials used.
3. Joints: Describe the different types of joints (e.g., expansion, contraction) and their importance in accommodating pavement movement.
4. Formwork: Discuss the role of formwork in shaping the concrete slabs and ensuring correct alignment.
5. Reinforcement: Mention the need for reinforcement and how it contributes to the strength of the pavement.
6. Conclusion: Summarize the significance of each component in ensuring the longevity and performance of rigid pavement.
