Description: In 2018 the American Association of State Highway and Transportation Officials (AASHTO) published the AASHTO LRFD Guide Specifications for Accelerated Bridge Construction. This AASHTO document contains specifications for multiple bridge precast substructure connections that have been thoroughly researched and implemented across the country. To go with these guide specifications, in 2022 the Precast/Prestressed Concrete Institute Northeast (PCINE) Bridge Technical Committee (which includes State DOT representatives from CT, MA, ME, NH, RI, NY, VT) published the PCINE Guidelines for Precast Substructures used in ABC. This PCINE document updates recommended guide details that include many new connections and options for precast substructures. (Previous PCINE guide details published in 2012 focused on the use of grouted splice couplers for substructure connections.) Michael Culmo is the lead designer for the new PCINE guide details. He is also the principal author of the 2018 AASHTO LRFD Guide Specifications for Accelerated Bridge Construction. This presentation, sponsored by the ABC-UTC in conjunction with PCI Northeast, describes how these two guide documents can be used together to develop the details needed for cost-effective and durable precast substructures.
