As the weather varies the concrete expands and contracts. If there were no gaps the concrete would buckle and crack.
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.

People who work with concrete are commonly referred to as concrete workers or concrete masons. They specialize in mixing, pouring, and finishing concrete for various construction projects, such as buildings, roads, and sidewalks. Depending on their specific role, they may also be called concrete finishers or concrete contractors.
concrete due to lime which neutralizes acid and toxicities in rain thus purifying before it runs into storm sewers which goes into the waterways
Asphalt is used because primarily because it is cheaper than concrete. Asphalt is also more pliable, and can expand and contract in changing weather. Concrete, however, cannot expand or contract as well, so gaps are placed periodically to ease this tension or compression. Also Asphalt creates less noise than Concrete. it helps me walk better on da ground yasss very much
They are expansion gaps that allow for the expansion and contraction of the concrete.
No the roads are made out of asphalt.

Concrete are used without reinforcement bars on concrete roads.
Sidewalks and roads.
Hhh
Because the concrete will expand and the tar will become soft. So the concrete has room to expand. With out cracking.

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!
it is durable and hard thats why concrete pavement is used
