Causes of Bridge Deck Damage
The concrete in the decks can crack up due to numerous reasons. If you do not focus on treating the cracks, then the surface can further break. Untreated cracks can make way for water to cause major damage to the structure beneath the deck. Here are some factors that affect the Concrete slab deck of a bridge:
-
The constant movement of heavy-loaded vehicles on the bridge.
-
Failure to prevent shrinkage which is caused by the quick drying up of concrete.
-
Use of concrete without adequate water and cement ratio. Excessive water can weaken the concrete mixture.
-
Improper placement of expansion gaps.
-
Extreme weather conditions can cause cracks to form. The hot temperature causes the concrete to expand while the cold temperature contracts it. This contraction and expansion can cause cracks in the deck.
-
Chemical and oil spills from vehicles can erode the surface of the concrete.
-
The freezing and thawing of water during winter will expand the cracks. The water also can seep into the substructure and deteriorate it.
The above points can become the reason for structural failure in the future. However, you can prevent major damage by taking the necessary steps as soon as possible. With the help of professionals, you can ensure that the structure's longevity is maintained.
Let us see some various techniques that the specialists apply to repair the deck.
