Yes. Bridge expansion joints are an important structural feature. Most sit flush with the road, and you likely wouldn’t even notice if you were driving on one. Without them, a large bridge would face severe damage over time and could even collapse.
Expansion joints are often installed during the construction process. Alternatively, they can be inserted into pre-existing structures or repaired by bridge remediation specialists. The installation process is performed by removing a section of concrete that spans the entire width of the bridge and inserting the metal expansion joint in its place.
They are used to allow concrete bridges to expand and contract without undergoing any structural damage. Expansion joints work by absorbing the stress and impact that comes with swaying, movement, pressure over top and changes in temperature.
This will depend on the thickness of concrete and length of the structure. Generally, expansion joints will be placed every 200 feet or so on a large bridge.
Yes. These joints are what allows the concrete to breathe. Concrete is an extremely hard material but it does not handle movement well. If not given the appropriate amount of room to shrink and grow, it will crack.
It all depends on how long the driveway is and what sort of environmental conditions it will be under. In most cases, control joints will be enough to prevent the concrete from cracking. These control joints should be cut at intervals around 25-30 times the thickness of the slab. For example, if the slab is 15cm thick, you would place your control joints every 4 metres.
By thermal expansion. This is a process where external heat is absorbed by a material, causing it to increase in size. Without getting too technical, when heated, the molecules within the structure start to move around more quickly — meaning they take up more space. It’s the same reason you might notice your car tyre pressure is higher on hotter days.
Bridge joints are any type of joints included in bridges to prevent them from cracking over time. These can include sliding plate joints, compression seal joints, asphaltic plug joints, poured sealant joints and more.
Expansion joint covers (EJCs) are a simple and convenient way to cover up an exposed expansion joint. Sliding over the top of the joint, it will expand and contract with the joint, keeping it protected and unexposed the entire time.
