Concrete, like most materials, expands and contracts with the temperature. The gaps allow the surface to do so without cracking.

How do sidewalks deal with thermal expansion?

Sidewalks are designed with expansion joints or gaps to accommodate thermal expansion without causing damage. These gaps allow the concrete to expand and contract with temperature changes, preventing cracks and distortion in the sidewalk surface. Additionally, materials with lower thermal expansion coefficients may be used to minimize the effects of temperature fluctuations on the sidewalk.


Why is important to place gaps at regular intervals in sidewalks?

To prevent sidewalks from cracking in random spots and breaking apart, builders make lines in sidewalks. The technical term for sidewalk lines is contraction joints. Contraction joints are placed in fresh concrete before the concrete dries and has a chance to create its own joints, which we call cracks.

What is the function of the gaps at the railway?

It depends which gaps you mean! Older track was laid in discrete sections with gaps left between them to allow for expansion on hot days. There are gaps between rails at the points which are used to connect different tracks together in turn. Is this what you mean?
