Permeability specifications for high-performance concrete decks

Abstract

Durable concrete exposed to the environment requires a proper air-void system for protection against cycles of freezing and thawing. Durable concretes also must have low permeability to resist the infiltration of harmful solutions into concrete. Work was conducted by the Virginia Department of Transportation (VDOT) on the permeability of concretes. Information is provided on permeability, recent VDOT efforts with a low-permeability specification, and the field application of the low-permeability specification.
