The Most Reliable Bridge Rehabilitation Is Here
We simply look to hire the finest talent and place the right individuals in the right roles to deliver the wide mix of skillsets necessary to grow our business. We don't use the number of years spent in the industry as a barometer of success or leadership abilities. Bridge restoration or bridge rehabilitation refers to the process of restoring a bridge's full functionality. Our bridges are deteriorating due to a variety of issues nowadays. Vehicle weight, pollution, and poor maintenance are a few of the things that contribute to the decline of our structures.
When there are no major problems and little to no repairs, bridge structures undergo preventative maintenance, also known as preservation. However, bridges that require significant repair work may need to be replaced or repaired. The most expensive option is to replace or rebuild a bridge, however this may be necessary if it has been neglected or has been severely damaged by forces. Normally, while repairs are being made to the structure, traffic is restricted or shut down.
In contrast, rehabilitation is a reliable repair method that balances repair costs while keeping a structure open to traffic. As long as the finished product offers the public a safe and appropriate service, rehabilitation is often preferred.
Joint Repair and Replacement
In this case, expansion joints are repaired or replaced to expand the working life of a bridge. If not done on time, these failing joints can cause additional damage to the bridge substructure and augmented spalling.
Structural Steel Rehabilitation
If a bridge sustains impact damage, steel rehabilitation and repairs include heating the bridge girders and members to straighten them. Depending on the inspection and diagnosis, welding repairs, bridge bearing replacement and resetting, as well as emergency structural repairs and mitigation, may be required. The removal and replacement of bridge structural members, structural rehabilitation, and strengthening are additional steel repair techniques.
Bridge Rehabilitation Techniques
There are lots of elements that need to be considered while choosing the most effective approach to bridge rehabilitation. The chosen approach primarily impacts the three prominent areas of a bridge – Substructure, Superstructure, and the bridge back.
Substructure Rehabilitation
When footings and pilings become exposed due to erosion, scour, and other destructive processes like the cycle of wetting and drying, there is a loss of bearing capacity. A bridge's pier and abutment's deteriorating concrete should be evaluated to see if the concrete is still sound or if substructure restoration is necessary. Additionally, steel pilings should be evaluated below the water line or splash zone when structures are erected on the water since corrosion is a problem.
Widening & Reinforcement
If the current deck is adequate and if the existing width is greater than half of the entire new width, deck widening can support the rehabilitation of a structure. If more than 20% of the deck has spalled or delaminated, it should be replaced. Concrete jacketing, steel plate, external post-tensioning, bonding of fiber-reinforced polymer (FRP) to the bridge's exterior surface, and pre-stressed concrete constructions are all strengthening approaches.
