SPR-4840: Physics-based Modelling of Concrete Degradation Phenomena: Impact of Construction Defects on Long Term Cost and Material Properties

This project aims at providing a methodology to quantify the additional costs that certain construction defects (with excessive air voids, in thin and rigid deck overlays) will have on the service life of a bridge deck. The performance of the deck throughout its life span will be described using the concepts of durability and service load performance such as cracking and deflections. A stochastic chemical-mechanical model will be developed, for both standard and non-standard construction cases, including the effects of properly and improperly executed interventions on the concrete deck. Recommendations will be identified.
