No the roads are made out of asphalt.

Concrete are used without reinforcement bars on concrete roads.
Sidewalks and roads.
Hhh
As the weather varies the concrete expands and contracts. If there were no gaps the concrete would buckle and crack.
Because the concrete will expand and the tar will become soft. So the concrete has room to expand. With out cracking.

It is unknown who came up with the idea to pave roads with concrete. The first concrete paved road was built in 1909 and was Woodward Avenue in Detroit, Michigan.
Nowadays, roads are mainly made of concrete. So... 1. When it rains, water seeps into the soil [normally, with mud roads] But since concrete does not allow water to seep in, the groundwater level is also affected, since we only take the water from underground, never recharge it. 2. Roots of plants need air. So if roads are built nearby the tree will die. 3. Microorganisms under the soil are also affected.
Tires are made with rubber. Asphalt roads are made with petroleum products. Both are naturally black in color. Of course, concrete roads are normally beige, the natural color of concrete. And I've seen local roads paved with a concrete/stone mix made using red shale, and they have a strong pinkish hue!
