Some images taken from a recent MAWTS Ageing Infrastructure site visit to the Woodside Section of the M8 Motorway. The viaduct comprises a combination of steel reinforced and post-tension concrete beams supported on reinforced concrete pier heads, utilising half-joint detailing.
Inspections revealed extensive corrosion of steel reinforcement and spalling of concrete - deterioration mechanisms which are all too familiar with half-joint configurations. Subsequently, major works are currently in progress along the viaduct.
These issues begin to raise questions such as: What are half-joints? Why are they in the condition that you see? Based on their current condition, how can we assess the impact that these deterioration mechanisms have on the load-capacity of the structure? Would you, a member of the public or even a practising engineer, notice such deterioration in your daily commute? If so, would you know how and who to contact to raise any concerns?
These are all questions that we, at MAWTS, are working hard to provide solutions to. With the help from you, the general public, we can raise awareness regarding ageing infrastructure and potentially highlight issues at an early-stage, saving not only time, money and human resources, but also lives.
