Chapter 2. COMPILATION OF INFORMATION AND SPECIFICATIONS FROM HPC BRIDGES

OBJECTIVE AND SCOPE

The objective of task A was to collect and compile information on concrete mixtures, concrete properties, research projects, girder fabrication, bridge construction, live-load tests, and specifications from each of the joint State-FHWA HPC bridge projects and other HPC bridge projects. This includes all information related to material properties and structural performance.

Information from a total of 19 bridges located in 14 States was collected. The States, abbreviated bridge names, and bridge locations are listed in table 1.

CD-ROM COMPILATION

The information collected to date has been placed on a CD-ROM for easy retrieval and viewing. On the CD-ROM, the information is presented in two formats. The first format consists of an individual compilation for each bridge. Each compilation contains information that is similar to that shown in tables 2 through 11 of this report. However, more details are provided in the compilation.

The compilation is divided into the following sections:

  1. Description: This section contains a summary of the overall bridge features.

  2. Benefits of HPC and Costs: Highlights why HPC was used in the bridge and provides total cost, cost per square foot, cost per foot, or any other information that was obtained.

  3. Structural Design: Lists essential features about the structural design of the bridge.

  4. Specified Items: This section includes relevant items that were required by the HPC special provisions. If items were not identified as being specified, the line is left blank.

  5. Concrete Materials: This section lists information obtained before actual construction of the bridges. It represents the information that would normally be submitted for approval of concrete mix proportions plus additional data that were available because of the research component.

  6. Concrete Material Properties: This section contains information obtained during the actual construction. It is separated into sections on material properties from quality control (QC) tests and material properties from research tests. Separate sections are provided for each HPC element used in the bridge, such as girders and deck.

  7. Other Research Data: This section contains research data specifically related to the construction of the showcase bridge. The information varies considerably between compilations depending on the approach and interests of the researchers.

  8. Other Related Research: This section contains other research information that was usually obtained prior to construction of the bridge.

  9. Sources of Data: References for documents used for the compilation are listed. Some of the data were obtained directly from the States and do not appear in the published data. The names of individuals who supplied the data are listed.

  10. Drawings: This section contains miscellaneous details to clarify the written information.

  11. HPC Specifications: When available, the special provisions for HPC in the bridge are included.

The compiled information from each bridge may be opened as a Microsoft® Word file from which a hard copy can be printed. For some of the data shown as graphs, the data are available in Microsoft® Excel files. For proper execution of these options, it is necessary to have Word or Excel available on the computer being used to view the CD-ROM. Otherwise, all other software is contained on the CD-ROM.

The second format on the CD-ROM compilation consists of 10 summary tables that can be used to compare data from different States and different bridges. The information contained in the summary tables is not as detailed as the information in the individual bridge compilations. The 10 summary tables reflect the primary information contained in the following main sections of the individual bridge compilations.

  • Description (two tables).
  • Structural Design (one table).
  • Specified Items (two tables).
  • Concrete Materials (two tables).
  • Concrete Material Properties (three tables).

The summaries of the information in sections 4, 5, and 6 are divided into separate tables for the prestressed concrete girders and the cast-in-place concrete deck. The summary for section 6 is further divided into separate tables related to structural properties and durability properties. The summary information is included in tables 2 through 11 of this report. For comparison purposes, data originally in metric units have been converted to English units.

On the CD-ROM, information on a specific topic can be obtained by using the search option.

The CD-ROM is available in two versions. An interim version contained information collected during the first 15 months of this project. The final version of the CD-ROM contains all information collected for the project.

In the process of collecting the information, some inconsistencies in the data were noted. Attempts were made to resolve as many of these as possible within the time constraints of the project. Nevertheless, some inconsistencies still remain. Also, for most of the bridges, it was not possible to obtain all of the information listed in the compilation. Although the information may exist, obtaining 100 percent of the detailed information proved to be difficult and time-consuming. Blank spaces in tables 2 through 11 indicate that the data may exist, but were not collected or compiled.

1 Ohio bridge used had 5.5-inch-thick (139.7-mm-thick) top flange of the box beam and 3-inch-thick asphalt.
2 The terminology is that used by the States. In general, wet curing and moist curing represent the same procedures.
3 May–September only. For November–March, membrane curing with insulated blankets was specified. For April and October, either method was allowed.
4 Includes 21 days at 100 degrees Fahrenheit ( °F) (37.8 degrees Celsius (°C)).

1 Ohio bridge did not have a separate concrete deck. Values are for the abutments.
2 Not more than 1.5 inches (38.1 mm) greater than the slump of the approved mix design.
3 The terminology is that used by the States. In general, wet curing and moist curing represent the same procedures.
4 May–September only. For November–March, membrane curing with insulated blankets was specified. For April and October, either method was allowed.
5 Includes 21 days at 100 °F (37.8 °C).
