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

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

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

  Pennsylvania - None to date. HPC use on decks is increasing. Has
  Concerned with redecking --  standard specification criteria. Uses rate
  ie. thin top slabs may be an of strength gain and a maximum strength of

  West Virginia -- None to     
  date. Producers are located  
  primarily in Kentucky.       
  Evaluating future use.       

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

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

  New Jersey -- Unknown        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.

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