Asphalt concrete is like a giant cake that is made up of asphalt and small rocks called aggregate. Imagine if you were making a cake, and you mixed all the ingredients together, like the flour, sugar, and eggs, then you put it in the oven to cook. Asphalt concrete is made in a similar way, but instead of the ingredients we use for baking, we use asphalt, which is like a glue, and little rocks or sand.
Asphalt is similar to the glue you might use to glue macaroni to paper or crafts together. When the asphalt is mixed with the rocks or sand, it creates a sticky substance that can be spread out like a giant pancake. When it dries, it becomes hard and strong like a sidewalk.
Asphalt concrete is used to make roads, parking lots, and even airports. It's important because it provides a smooth and safe surface for cars and people to drive and walk on. Just like a cake needs icing to make it pretty, we also put stripes and signs on the asphalt to make it easier to see and to tell people where to go.
So basically, asphalt concrete is like a big, strong cake made of rocks and glue that we use to make roads and other surfaces safe for driving and walking.
