Internal Curing as a New Tool for Infrastructure Renewal: Reducing Repair Congestion, Increasing Service Life, and Improving Sustainability

Record Type: UTC
This research proposes a holistic perspective to quantify the potential benefits of internally cured concrete mixtures compared to conventional concrete mixtures in a transportation system. This research will seek to determine the opportunity costs and the short-term, long-term, and life cycle savings arising from the traffic side. These include: (i) quantifying the durability under various congestion/demand levels, (ii) analyzing the costs-benefits ratios under various traffic conditions to determine the optimal situations which would warrant their usage for bridge decks, (iii) the opportunity costs associated with avoiding renewal/repair expenses and traffic disruption impacts due to the reduction in the frequency of repair and renewal, (iv) the traffic situations in which they are warranted as replacements compared to conventional concretes, and (v) whether they can be used as effective and sustainable repair mechanisms in high traffic areas to reduce the negative impacts of traffic disruptions. In addition, this work will seek to ascertain the environmental impact of using these materials.
