About the research

Abstract: This project was done in conjunction with a laboratory project to evaluate the potential of fibercomposite and stainless steel as a form of joint reinforcement for concrete pavements. The objective of the work is the evaluation of two composite products and one stainless steel product in the reduction of deflections and corrosion in transverse and longitudinal pavement joints over a five-year period. The bars have been installed in a pavement near Des Moines and were evaluated twice each year for five years.
