Project Objective
The study objectives are
• Life-cycle maintenance cost analysis within the context of PBMC.
• Use accelerated aging tests to determine the effect of saltwater environment on the residual strength of CFFT and HDS-FRP/S
• Investigate the effects of combination of temperature cycles, high moisture, and UV radiation on the residual strength of CFFT and HDS-FRP/S
• Investigate the effects of chloride solution on the residual strength of HDS-FRP/S

Project Abstract
The Federal Highway Administration (FHWA) requires that state highway agencies preserve and maintain existing roads so that the highway systems work better and last longer. This is a major part of the Asset
Management goals undertaken by the federal government. The goal of this research is to assist Missouri Department of Transportation (MoDOT) in identifying opportunities to use performance-based maintenance
contracting (PBMC) in their road maintenance activities. This research will focus on benefits of using this innovating contracting method and will determine the MoDOT road maintenance activities that can be
performed under performance based contract.

Relationship to other Research/Projects

Currently, the PI has another project where he investigates the cyclic performance of concrete filled fiber reinforced polymer tubes.

Technology Transfer Activities

Meetings with NDOT and MoDot engineers will be held
to disseminate the results of the project.


Project Deliverables

A report and presentation at the NUTC annual meeting

Anticipated Benefits

Recent studies have shown that PBMCs can reduce the maintenance cost by up to 50%. Crucial element in PBMC is to determine performance indicators and to calculate the maintenance cost.
This research will provide the required data to calculate the life cycle maintenance cost of recently developed bridge columns including concrete filled fiber reinforced polymer tubes and hybrid double skin fiber reinforced polymer/steel tubes.
