Advanced Materials, River And Coastal Engineering
Detail of the task Part A (Materials)
A 55 year old river bridge has piers showing signs of abrasive wear, delamination and spalling of the concrete exposing the steel reinforcement beneath. You are required to evaluate the condition of the piers by recommending a critical review of the structure using non-destructive testing (NDT) methods, particularly in terms of the cover and the corrosion of the steel reinforcement.
Part B (River & Coastal)
Part of the river adjacent to the bridge, is designed as a flood alleviation scheme, as the level of the river can become dangerously high during periods of cold weather, when broken sheet ice causes fouling of the bridge spans. Critically evaluate the need to maintain a steady flow between the bridge piers to prevent over-topping of the flood defences and consider the implications for extensive flooding of the local area.
As part of the overall critical evaluation of the bridge and flood alleviation measures, you are required to propose a suitable reinforced concrete pier protection system to break up the approaching sheet ice preventing fouling and to prevent erosion damage to the bridge piers.
As part of the recommendations, you should also consider the proposed concrete mix design to provide suitable durability as well as protection of the steel reinforcement.
Supporting literature relating various levels of exposure to the possible types and rates of degradation should form an essential part of your submission with suitable citations and referencing using the Harvard method.
