The joint doesn't prevent expansion and contraction but it limits the damage caused by thermal stress. It allows room for the concrete ( or steel ) to expand and contract without creating the severe cracks that would form without them.

Why do railway lines have gaps in them?
to allow for the thermal expansion or contraction
What are the effects of expansion and contraction in the design of bridges pavements and MRT lines?
- MRT and Railway tracksif a continuous track of metal is used, it will expand in hot weather and bent. trains running on bent tracks may be derailed. to prevent this, railway tracks are laid in sections with expansion gaps between them. A sliding joint between adjoining rails allows them to expand without bending.- bridgesboth concrete and steel bridges are built with allowance for expansion and contraction due to changes in the surrounding temperatures. Rollers and sliding joints allow for the movements of the bridges as it expands and contracts
What is a expansion loop?
a complete loop installed in a pipeline to mitigate the effect of expansion or contraction of the line.
Why do civil engineers have to consider expansion and contraction?
they just do ok god
What are the Rates of expansion and contraction of cast iron and steel and brass and cpvc pipe?
The coeifficent of expansion per degree can be found in the manufacturers charts
Why are railroad tracks built with a flexible expansion and contraction joint?
The tracks have a larger coefficient of linear expansion than the ground beneath.
Why would a bridge contain gaps where the metal pieces fit together?
these gaps "joint" are used to prevent cracking due to expansion and contraction which result from the change in temperatures between summer and winter and night and day
What is the travel joint in oil well completion?
it is a barrel and mandrel can move in each other to absorb expansion and contraction of the tubing.
The difference between contraction joint and construction joint?
A construction joint in concrete jobs is a joint where a fully set and hard concrete joins a fresh concrete to make a joint. Normally, cracks would occur at this joint because concrete was not cast monolithic. A contraction joint is joint between two concrete edges so formed which allows minute movement between the two edges caused by heat or some other external forces. Usually, contraction joints are also referred to as expansion joints.
What is the antonym for contraction?
Expansion is the antonym for contraction.
What is the difference between contraction and expansion?
In contraction the size of item becomes smaller. In contract, expansion increases it.
What are the release dates for Expansion and Contraction - 1903?
Expansion and Contraction - 1903 was released on: USA: January 1903
Do you agree that expansion and contraction only cause problems?
No, we use expansion and contraction to tell temperature(thermometer).
Why do you use a construction joint?
Construction joints are very useful, the expansion & contraction made is made in summer & winter season respectiely. In summer coz of temprature concrete get expansion in mm but it damage the structure, that's why construction joint is provided. Sunil Nagargoje TESPL
Air expansion and contraction?
expansion is when the air is HOT !
What is the difference between Rubber Expansion joint and Dismentaling joint?
rubber expansion joint is a rubber and dismentaling joint is mental joint
What does an expansion tank do?
Allows for expansion and contraction of various systems
