Condition Survey for Bridge Decks

4 Methods of Condition Survey for Bridge Decks

Exposed Concrete Decks suffer from various deterioration mechanisms; i.e. freezing and thawing, corrosion. The most significant consequence is the delamination of concrete, which could eventually trigger other damage mechanism, such as corrosion. The maintenance of deck slabs is quite challenging mainly because it normally involves large areas; In many cases, closing the deck to traffic Read more about 4 Methods of Condition Survey for Bridge Decks[…]

How to Use GPR for Evaluation of Concrete Piles

How to Use GPR for Evaluation of Concrete Piles

Detection and evaluation of unknown foundations of old construction, particularly buried piles can be a big challenge, because: * No structural drawing is available. * The access to the piles is difficult, if not impossible. * The traffic or operation of (or over) the superstructure can not be interrupted. Certain non-destructive methods have been developed over years Read more about How to Use GPR for Evaluation of Concrete Piles[…]

Reinforced Concrete Bridge Deck Investigation

In this article, we will review the application of GPR in bridge deck investigation. Investigating concrete bridge decks can be labor-intensive and time-consuming. Many investigation techniques have been developed over time to study defects in the decks. Corrosion of steel reinforcement is a major challenge in concrete decks, as it remains unnoticed until it is Read more about Reinforced Concrete Bridge Deck Investigation[…]
