A pavement is the ground surface of a road or path that people walk or drive on. It's made of different materials like stone, asphalt, or concrete.
We use the word "pavement" all the time when we're talking about getting around town. If you're walking down the street and there's been construction, they might be working on the pavement to fix potholes or repave it entirely. If you're driving, you'll probably notice road signs that tell you to watch out for work being done on the pavement. Some cities even have separate bike paths made of pavement just for cyclists.
(now chiefly in technical contexts) A paved surface; a hard covering on the ground.
