Download or read book Performance Testing of Experimental Dowel Bar Retrofit Designs written by Nicholas A. Popehn. This book was released on 2003. Available in PDF, EPUB and Kindle. Book excerpt: Effective load transfer across Portland cement concrete pavement joints significantly decreases pavement deterioration. Areas of concern with using dowel bars include high costs, due to the labor-intensive procedure of retrofitting, and corrosion associated with standard mild steel epoxy-coated dowels. This research addresses these problems by evaluating four dowel bar details tested in an accelerated manner. Retrofit testing was performed using mild-steel epoxy coated dowels and fiber reinforced polymer (FRP) dowels. The details tested provide comparisons among dowel bar materials, depth of placement, number of dowels used, and dowel diameter. Verification testing of previously tested details is also presented.
