Bridges, tunnels and other road structures are presently designed to achieve their design life requirement of 100 years. This may not necessarily lead to a cost-effective outcome and all asset owners are seeking the lowest whole of life cycle cost…

Durability assessment is increasingly becoming an integral part of infrastructure design projects in Australia. One of the key drivers for this is the requirement by asset owners for optimum whole of life cost, minimum construction period and…

The Infrastructure Asset management is facing critical demand and challenges in encountering the concerning issues pertaining to the existing bridges due to un-foreseen accidents. The emergency issues arising due to possible vandalism, low height…

The near-surface mounted (NSM) FRP technique has received attention worldwide over the externally bonded FRP strengthening technique. Strengthening of a concrete girders using fiber reinforced polymer (FRP) composites to flexural and shear…

Collecting, processing, and administering data from bridge inspections underpins bridge lifecycle management. Although, the inspection process and identification of material defects is well defined and documented, little guidance is given on systems…

Theoretical assessments of a bridge network to AS5100.7 identify many bridges operating at margins smaller than those embodied in AS 5100.7. The cost of strengthening these bridges is unpalatable and the consequences of restricting access are…

Roads and Maritime Services, New South Wales is responsible for managing over 5600 bridges and bridge size culverts, with a written down value of 12.5 billion and a replacement cost of 18.2 billion. Roads and Maritime bridge stock is the oldest and…

The Huntly Section is a new NZ$415M section of the Waikato Expressway running between Hamilton and Auckland. It will connect the recently completed Ngaruawahia and Ohinewai sections on a route that traverses the Taupiri Ranges within a deep cutting…

In recent years the circumferential wrapping with externally-bonded carbon fibre-reinforced polymer (CFRP) composites has proven to be a promising method for strengthening concrete structures. This is particularly valuable when repairing concrete…

Prestressed concrete I girder bridges constructed in the 1960s and 70s have the potential to restrict transport productivity because their AS 5100.7 assessments can be poor despite satisfactory inservice performance. The primary issue is the shear…
