BACKGROUND

With the understanding of the advancements in the use of pozzolanic concrete to reduce carbon dioxide emissions, the Senate Committee on Environment and Public Works has requested reports on the use of low-carbon materials, including pozzolanic concrete, in federally funded projects. The request noted that the report should include steps taken to assess the durability, strength, cost, and environmental impacts of pozzolanic concrete compared with existing concrete products. The U.S. Department of Transportation Office of the Assistant Secretary for Research and Technology (US DOT OST-R), in coordination with the Federal Highway Administration (FHWA), will submit to the Committee a report on the use of pozzolanic concrete in federally funded infrastructure projects. The US DOT OST-R requested the TRB Cooperative Research Programs (CRP) to facilitate the conduct of this work and the preparation of the requested report. Research is needed to document the use of pozzolanic materials in concrete used in infrastructure projects and prepare the requested report.

OBJECTIVE 

The objective of this project is to document the use of pozzolanic materials in concrete used in infrastructure projects and prepare reports on the state of practice of pozzolanic concrete in infrastructure projects and in federally funded infrastructure projects. The latter report shall be prepared in a format appropriate for submission to the U.S. Congress. The research shall consider the use of fly ash, silica fume, and other pozzolans, both singularly and in combination. The documentation shall include the criteria and methods used to assess suitability of these materials for use in concrete structures, e.g., concrete properties such as durability and strength, estimated service life, economic considerations, and environmental impacts. For this project, pozzolanic concrete is defined as concrete containing pozzolanic materials. The research shall consider FHWA funded projects, projects located on federal lands, and projects using the formula and discretionary grants funds.

Accomplishment of the project objective will require at least the following tasks.

TASKS

Task descriptions are intended to provide a framework for conducting the research. The CRP is seeking the insights of proposers on how best to achieve the research objective. Proposers are expected to describe research plans that can realistically be accomplished within the constraints of available funds and subaward time. Proposals must present the proposers' current thinking in sufficient detail to demonstrate their understanding of the issues and the soundness of their approach to meeting the research objective.

PHASE I

Task 1. Review literature, ongoing research findings, and current practices relevant to the use of pozzolanic concrete in infrastructure projects, specifically, federally funded infrastructure projects. This information may be assembled from published and unpublished reports, coordination with FHWA and other agencies on databases available, contacts with and surveys of federal and state agencies and industry organizations, and other sources.

Task 2. Prepare and submit within 5 months from subaward, (a) a pre-draft Report 1 on the state of practice of pozzolanic concrete in infrastructure projects and (b) an outline of Report 2 on the state of practice of pozzolanic concrete in federally funded infrastructure projects (to be prepared in Task 4.) At a minimum, each report must address the following:

1. Extent of use of the different types of pozzolanic concrete for construction and rehabilitation of infrastructure projects,

2. Properties of conventional and pozzolanic concretes used in infrastructure projects that influence performance and service life,

3. The factors (e.g., mechanical properties, other non­material factors including cost, environmental impacts) and approaches (e.g., service life, life-cycle analysis) used for comparing pozzolanic concrete to conventional concrete and selecting concrete type, and

4. The actual comparison of pozzolanic concrete to conventional concrete.

Note: Following review of pre-draft Report I and the outline of Report 2 by the CRP, the research team will be required to meet with CRP and make a presentation to the CRP project panel within 1 month of report submission. Work on Phase II of the project will not begin until the interim report is reviewed and the Phase II work is authorized by the CRP.

PHASE II

Task 3. Review and consider the comments on the pre-draft Report 1 and prepare a draft version of the report, to be included as part of the draft final deliverable.

Task 4. Review and consider the comments on the outline for Report 2 and prepare and submit within 8 months of subaward a pre-draft Report 2 on the comparison results and state of practice of pozzolanic concrete in federally funded infrastructure projects. Report 2 shall discuss the rationale for using pozzolanic concrete for these projects and delineate the steps taken to assess its suitability of use in these projects and be prepared in a format appropriate for submission to the US DOT OST-R.

Note: Following review of draft Report 1 and pre-draft Report 2 by the CRP, the research team will be required to meet with CRP and make a presentation to the CRP project panel within 1 month of submission. Work on Phase III of the project will not begin until the pre-draft report is reviewed and Phase III work is authorized by the CRP.

PHASE III

Task 5. Review and consider the comments and revise pre-draft Report 2.

Task 6. Prepare and submit for CRP review, within 10 months of subaward, a 2-part draft final deliverable that includes (a) draft Report 1 on the state of practice of pozzolanic concrete in infrastructure projects, and (b) draft Report 2 on the state of practice of pozzolanic concrete in federally funded infrastructure projects.

Note: Following receipt of the draft final deliverables, the remaining 2 months shall be for CRP review and comment and for research agency preparation of the final deliverables.

 SPECIAL NOTES

A. Revisions to the Information and Instructions for Preparing Proposals for the Transportation Research Board’s Cooperative Research Programs are highlighted in yellow within that document.

B. Proposals must be submitted as a single PDF file with a maximum file size of 10 MB. The PDF must be formatted for standard 8 ½” X 11” paper, and the entire proposal must not exceed 60 pages (according to the page count displayed in the PDF). Proposals that do not meet these requirements will be rejected. For other requirements, refer to chapter IV of the instructions.

C. The Information and Instructions for Preparing Proposals for the Transportation Research Board’s Cooperative Research Programs have been modified to include a revised policy and instructions for disclosing Investigator Conflict of Interest. For more information, refer to chapter IV of the instructions. A detailed definition and examples can be found in the CRP Conflict of Interest Policy for Subawardees.
