Rigid pavement is a type of road surface made from concrete. It is designed to distribute loads over a wide area, which helps prevent cracking and deformation. Rigid pavements are often used for highways, airport runways, and heavy traffic areas due to their durability and strength. One of the key features of rigid pavement is its ability to maintain its shape under heavy loads. This is achieved through the use of reinforced concrete, which includes steel bars or mesh to enhance strength. Rigid pavements typically require less maintenance compared to flexible pavements, making them a cost-effective choice in the long run.
