There are 2 reasons for that.
Reason one: They can be expansion joints. In the winter the pavement contracts and in the summer it expands. these joints are generally gaps that go the whole way threw the pavement. Generally these joints are filled with some sort of caulking to keep moisture from getting underneath the pavement.
Reason two: They can be put there as joints for the concrete to crack. when sidewalks are made and other concrete pavements, they anticipate the concrete cracking, so they put in gaps that dont go all the way threw the depth of the concrete as a place for the concrete to crack and not be unsightly.

∙ 14y agobecause it expands and contracts depending on the temperature..the gaps allow the concrete some space to expand so that it will not crack..

∙ 14y agoThey are for expansion, contraction and settling of the ground below to prevent concrete from cracking.

When temperature rises what will happen to the gaps between the concrete sections?
when the tempreture rises the gaps between the concrete pavement will expand because of the heat.
Why do you need water for when you have to go to the bathroom?
because water has healthy minerals and extracts can clean in gaps in your skin. if you are washing you're hands it cleans in between the the creases and gaps in your fingers and thumb
What is a curcuit in which there are no gaps?
If there are no gaps in a curcuit, it is a closed curcuit.
What is it called when you fill in gaps with what your senses tell us?
Perception is when you fill in the gaps with what your senses tell you.
What are the tiny gaps between adjacent schwann cells called?
Remember that the Schwann cells are made of myelin sheath which insulate the impulse, but also block the sodium ion/potassium ion channels. Therefore there has to be a point where the action potential 'jumps' to, and these are the gaps between the Schwann cells, they are called the Nodes of Ranvier.
Why did concrete slabs used to make motorways have a soft material in the gaps between them?
It allows for the expansion of the concrete during hot weather and provides a water block during rains and that prevents water freezing (and expanding) during the winter. Ice expanding in those cracks would damage the cement slabs.
Why do roads have the gaps between the large pieces of concrete?
They are expansion gaps that allow for the expansion and contraction of the concrete.
Why do concrete roads have gaps between large pieces of concrete?
As the weather varies the concrete expands and contracts. If there were no gaps the concrete would buckle and crack.
When temperature rises what will happen to the gaps between the concrete sections?
when the tempreture rises the gaps between the concrete pavement will expand because of the heat.
When the temperature rises what will happen to the gaps between the concrete sections?
when the tempreture rises the gaps between the concrete pavement will expand because of the heat.
Why concrete highways are made in short sections with tar-filled gaps between them?
The tar gaps are where the hwy has been repaired.
Why are concrete highways made in short sections with tar-filled gaps between them?
The tar gaps are where the hwy has been repaired.
Why are there gaps in between sidewalks?
Concrete, like most materials, expands and contracts with the temperature. The gaps allow the surface to do so without cracking.
Why gaps are left in concrete slaps?
With the weather the concrete can expand or contract and the gaps in the concrete are left to allow for this expansion of contraction so the concrete doesn't crack or break.
What is a Vallie?
Formed as large slabs of rock sink and slide down into gaps in the crust
What are expansion gaps?
Expansion gaps are the controlled gaps between the structure. The gaps purpose is to compensate and go with the changes of the structure overtime.For example: Materials such as concrete shrink overtime and clay expand slowly. So, it is needed for the structure to have expansion gaps to avoid damages.
Why concrete highways are made in short sections with refilled gaps in between them?
To allow for expansion in hot weather
