because it expands and contracts depending on the temperature..the gaps allow the concrete some space to expand so that it will not crack..
They are expansion gaps that allow for the expansion and contraction of the concrete.
As the weather varies the concrete expands and contracts. If there were no gaps the concrete would buckle and crack.
Gaps in concrete roads are filled with tar, also known as joint sealant, to accommodate the expansion and contraction of concrete due to temperature changes. This helps prevent water infiltration, which can lead to freeze-thaw damage and deterioration of the road surface. Additionally, filling these gaps reduces noise and provides a smoother driving experience. Overall, it enhances the longevity and structural integrity of the road.
when the tempreture rises the gaps between the concrete pavement will expand because of the heat.
when the tempreture rises the gaps between the concrete pavement will expand because of the heat.
During winter when the concrete contracts/shrinks and there is no gap, then it will crack from the surface. So gaps are left in concrete such that it can shrink to a safe limit without cracking it.
concrete compared to human strength is very strong but with so many cars,bikes,people ect. it can easily crack to stop this happening they but black tar under and on the sides so its is stronger and less likely to crack.
When the temperature rises on concrete without any gaps, the concrete expands. This expansion can cause stress within the concrete structure, leading to potential cracks or damage if the temperature change is significant. The lack of gaps restricts the concrete's ability to expand freely, which can result in structural issues over time.
No the roads are made out of asphalt.

concrete
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
