Project Objective

The objective of the proposed research is to develop, test, and evaluate fiber-reinforced, polyurethane foams to replace the costly honeycomb construction currently used to manufacture FRP bridge deck panels, thus making them more cost effective and a viable alternative to reinforced concrete.

Project Abstract

The proposed study will involve investigating alternative polyurethane foam formulations as potential candidates to replace the honeycomb construction currently used in FRP bridge deck panels. The purpose of this proposed research will be as a proof-of-concept and to obtain preliminary data for proposals to both federal and state funding agencies including NSF, NCHRP, FHWA, and MoDOT. Results from this research will establish this technique as a viable approach.

Project Deliverables

Test data, formulations, and recommendations for closed-cell, high-density polyurethane foams used as infill for fiber-reinforced bridge deck panels.

Anticipated Benefits

Cost-effective, corrosion-resistant bridge decks

Milestones

Relationship to other Research/Projects

This is a standalone project under the advanced materials theme of the Center for Transportation Infrastructure and Safety (CTIS) National University Transportation Center (NUTC) at Missouri S&T.

Technology Transfer Activities

The technology transfer activities will include a final research report and dissemination of the findings through a national conference via technical presentation(s) and publication(s).
