Indian Concrete Journal - ICJSummary: Increasing urban sprawl is resulting in buildings and inhabited areas being located closer to highways resulting in complaints regarding noise from traffic. Sound walls and noise barriers are often used to decrease noise. In the case of elevated bridges, the barriers have to be added to existing decks resulting in the need for substantial addition of overhang steel reinforcement to carry the additional load. In many cases related to older box-girder bridges, this either is not feasible structurally or requires substantial demolition of the existing structure with the consequent extensive disruption of traffic. The use of near surface mounted (NSM) fiber-reinforced composite (FRP) strips as additional reinforcement on the overhang region is shown to be an effective strategy enabling efficient and cost-effective rehabilitation of box-girder type bridge decks without extensive modification of the existing structure and much less disruption of traffic.
