Download or read book Design and Evaluation of Jointed Plain Concrete Pavement with Fiber Reinforced Polymer Dowels written by . This book was released on 2009. Available in PDF, EPUB and Kindle. Book excerpt: "This study evaluates fiber reinforced polymer (FRP) dowel bars as load transferring devices in jointed plain concrete pavement (JPCP) under HS25 static and fatigue loads and compares their response with JPCP consisting of steel dowels. Along with laboratory and field evaluations of JPCP with FRP and steel dowels, analytical modeling of dowel response was carried out in terms of maximum bending deflection, relative deflection (RD), and bearing stress of dowels. In addition, field rehabilitation of JPCP was carried out using FRP dowels to evaluate its long-term performance"--Technical report documentation page.

Book Synopsis Evaluation of Fiber Composite and Stainless Steel as Alternative Dowel Bar Material by : Jeffrey G. Hoffman
Download or read book Evaluation of Fiber Composite and Stainless Steel as Alternative Dowel Bar Material written by Jeffrey G. Hoffman. This book was released on 2002. Available in PDF, EPUB and Kindle. Book excerpt: Dowel bars are used to transfer loads between adjacent pavement sections within a jointed concrete pavement. Epoxy coated steel is the most common material used for dowel bars, but steel dowel bars have been found to be susceptible to corrosion. The objectives of this research is to investigate fiber reinforced plastic (FRP) and stainless steel as alternative dowel bar materials, and to study the effects of FRP and stainless steel dowels size and spacing on load transfer behavior of concrete pavements. The load transfer behavior of the pavement was evaluated biannually by utilizing a falling weight deflectometer (FWD), measuring joint faulting and joint opening, and conducting a visual distress survey. The analyses indicate the epoxy coated steel outperformed the alternative materials. The average research lifetime load transfer for the epoxy coated steel is 91 percent, while the best performance of the alternative material at the same 12 inch on center spacing is approximately 87 percent for the stainless steel. The data also indicate the decrease in spacing, from 12 to 8 inches, increases the load transfer for stainless steel and 1.5 inch diameter FRP dowels. Although the FRP dowels with decreased spacing were outperformed by the epoxy coated steel dowels, they performed adequately. It is recommended that the current dowel bar standard continue to be implemented for concrete pavements requiring dowels as load transfer devices. However, if the pavement is to be constructed in a corrosive environment or a longer design life is desired, stainless steel spaced at 12 inches and 1.5 inch diameter FRP dowels spaced at 8 inches should be considered.

Book Synopsis Evaluating the Use of Fiber-reinforced Polymer Bars in Continuously Reinforced Concrete Pavement by : United States. Federal Highway Administration
Download or read book Evaluating the Use of Fiber-reinforced Polymer Bars in Continuously Reinforced Concrete Pavement written by United States. Federal Highway Administration. This book was released on 2009. Available in PDF, EPUB and Kindle. Book excerpt: This TechBrief discusses the potential use of fiber-reinforced polymer (FRP) bars in continuously reinforced concrete pavements (CRCP). Relative advantages and disadvantages of FRP bars are presented, and some specific considerations for the use of FRP bars in CRCP design and construction are described. This is followed by an overview of two recent experimental CRCP projects that have been constructed with FRP bars.
