Research Start Date:
August 1993
Expected Completion Date:
August 1997
Research Objectives:
Fiber reinforced plastic (FRP) materials are showing great promise for use in highway structures because of their high strength, light weight, and resistance to corrosion compared to the materials traditionally used in highway bridges and structures. Moreover, the possibility of developing materials with a made to order set of properties is appealing to designers of highway structures. Because of the relative newness of these materials, their long term durability under adverse mechanical and environmental conditions of a highway structure has not been demonstrated. The acceptance of these materials will require the development of accelerated methods to determine their durability over the seventy year life of a highway bridge. This project is part of a three-university effort to develop suitable test methods to determine the long-term properties of FRP materials proposed for use in highway structures. The objective of the team at the Pennsylvania State University is the development of accelerated test methods for evaluation of FRP reinforcing materials to be used in concrete systems.
Expected Products or Deliverables:
It is expected that this research will result in a set of standardized testing procedures, suitable for adoption by ASTM and AASHTO, for acceleration of mechanical and environmental effects on the bond behavior of FRP reinforced concrete systems.
