Damage to concrete slabs during freezing and thawing cycles represents a major challenge to pavement durability and resilience. This brief explores freeze-thaw cycles in concrete using models that simulate water and ion transport. The research supports past findings that damage is not primarily caused by the expansion of
 freezing water in the cement paste, and points instead to the impacts of deicing agents that find their way into the material's nanostructures. The research suggests the need for an improved understanding of freeze-thaw and damage mechanisms in concrete, which will enable the development of models that can be used to predict long-term impact on pavements.
