yes, that is why they put expansion joints on bridges. (: your welcomeyes, that is why they put expansion joints on bridges. (: your welcome
The expansion joint in a sidewalk keeps the concrete from cracking just as what its called. It allows the concrete to expand when heated and contract when cold. Without the joint, the concrete will crack and become uneven or mountain up.
Yes , just the same as steel - otherwise the rebar would crack structures !
A little bit, but not much. If it is really hot, and then really cold, then your cement will crack.
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
the metal or concrete might expand if it gets too hot and compress when it gets too cold.
Material such as wood allow the concrete to expand
Because the concrete will expand and the tar will become soft. So the concrete has room to expand. With out cracking.

It is a concrete bridge so has no need to expand.
No. Concrete never gets any bigger than the day it is poured.

A concrete patio usually cracks due to heat cold. If it is to cold it contract and break. If it is to hot it will expand and break. Then water can seep into those cracks and freeze causing the crack to expand
when the tempreture rises the gaps between the concrete pavement will expand because of the heat.
because it expands and contracts depending on the temperature..the gaps allow the concrete some space to expand so that it will not crack..

Expand the following: 3 ( 2x +5 )
Those are expansion joints. During the changing seasons with varying temperatures, the slabs expand and contract. The spaces allow the slabs to expand without cracking the concrete.
