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.
What else can I help you with?
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.
What is the thing filling the space between concrete slabs called?
The material used to fill the space between concrete slabs is often called "joint filler" or "joint sealant." It helps prevent water and debris from entering the gaps, provides flexibility for movement, and can help extend the life of the concrete.
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.
When the temperature rises what might happen to the sections of concrete if there are no gaps between them?
As the temperature rises, concrete expands due to thermal expansion. Without gaps between sections, the concrete may crack or buckle as it has no room to expand. This can lead to structural damage and compromise the integrity of the concrete structure.
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 concrete highways are made in short sections with tar-filled gaps between them?
The tar gaps are where the hwy has been repaired.
Why gaps are left in concrete slaps?
Gaps in concrete slabs, also known as control joints, are intentionally placed to control cracking caused by shrinkage as the concrete cures. These joints help to direct where cracks may occur, allowing them to happen in a controlled manner along the joint lines rather than randomly across the slab. Without control joints, cracks may still form but they would be more unsightly and difficult to predict.
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.
What is a Vallie?
Formed as large slabs of rock sink and slide down into gaps in the crust
