Duracrete/fib Bulletin 34 Service Life Model and AASHTO Guide Specification for Service Life Design of Highway Bridges
Presented By: Brad Pease, COWI North America
Description: Various codes, standards, guidelines, and engineering tools (both open source and proprietary) exist to assess the service life duration of reinforced concrete structures exposed to environmental conditions that promote chloride-induced reinforcement corrosion. In this session, several of these tools will be implemented on theoretical structural components located in Boston with a required 100-year service life, including a bridge deck, a marine pile and a marine wall constructed from one of three prescribed concrete mix designs. In this presentation, the implementation and conclusions of the probabilistic-based modeling approach presented in the fib Bulletin 34 and prescriptive requirements from AASHTO Guide Specification for Service Life Design of Highway Bridges will be described.
