Pavements are flat surfaces made of stone, asphalt, or concrete that are used to provide a smooth and safe surface for pedestrians and vehicles. The term 'pavements' can refer to both macadams and roadways. Macadams are a type of pavement made from crushed stones and gravel that are bound together with tar or asphalt. Roadways are paved surfaces that are designed to accommodate motorized vehicles. Both macadams and roadways are important components of the transportation infrastructure.
