  Status of each State's implementation of PCEF Bulb T's and Implementation of HPC

Status of Implementation of PCEF Bulb T Shapes
Maryland - Unsure
Implementation of HPC
Woodrow Wilson Bridge, with fibers. Concerted effort to increase number of HPC bridges. Would like to see HPC used for prestressed beams

Status of Implementation of PCEF Bulb T Shapes
Delaware - Looking for first application
Implementation of HPC
2 bridges constructed with HPC and one superstructure. Microsilica used, 4" thickness. No early shrinkage cracks yet. Permeability of mixes was less than 1000 coulombs

Status of Implementation of PCEF Bulb T Shapes
Virginia - All beams are PCEF Bulb T's. Planning on doing one 93" beam.
Implementation of HPC
Extensive use of HPC for bridges and decks. Has done some 10000 psi bridges and some light weight.

Status of Implementation of PCEF Bulb T Shapes
Pennsylvania - None to date. Concerned with redecking - ie. thin top slabs may be an issue. Currently reviewing continuity details
Implementation of HPC
HPC use on decks is increasing. Has standard specification criteria. Uses rate of strength gain and a maximum strength of 6000 psi. Recently eliminated shrinkage criteria

Status of Implementation of PCEF Bulb T Shapes
West Virginia - None to date. Producers are located primarily in Kentucky. Evaluating future use.

Status of Implementation of PCEF Bulb T Shapes
North Carolina - None to date. Likes having producers submit to them as an option. Has used PCI Bulb T's
Implementation of HPC
Minimizes pozzolanic material volume for certain Districts in deck mixes. US-64, a 5 mile long bridge with HPC and a 100 year service life will be developed using a corrosion model. Each element will be based on a chloride concentration estimate. Air content not specified.

Status of Implementation of PCEF Bulb T Shapes
District of Columbia - Unknown
Implementation of HPC
Used on approximately 60% of their structures using 4500 psi concrete and a maximum permeability of 1500 coulombs. The North Capitol Bridge will be an HPC design

Status of Implementation of PCEF Bulb T Shapes
New Jersey - Unknown
Implementation of HPC
HPC will be used on their Long Port project for piles, pier caps and girders. Their Victory Bridge project will use HPC for segment box columns and footings. A full battery of qualification tests will be run, including creep, shrinkage, permeability and a minimum of 8000 psi strength.

Status of Implementation of PCEF Bulb T Shapes
New York - Uses New England Bulb T shapes. Allows substitution of PCEF shapes without calculations. In the process of developing new standards.
Implementation of HPC
Uses HPC on decks the last 10 years. The main problem they have experienced is with deck cracking, even with 14 day wet cure. Have used fibers recently, but results have not been quantified. Next year, all decks will be HPC. Bridge beams will use 10000 psi concrete.
