Design and Evaluation of Jointed Plain Concrete Pavement with Fiber Reinforced Polymer Dowels
This study evaluates fiber reinforced polymer (FRP) dowel bars as load transfering devices in jointed plans 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. Laboratory tests included static and fatigue load application corresponding to HS25 load and 1.5 times HS25 load on concrete slabs (27.94- and 30.48-cm (11- and 12-inch) depth) with 3.81- and 2.54-cm (1.5- and 1.0-inch) steel and FRP dowels at differenct spacings (30.48 and 15.4 cm (12 and 6 inches)). Both 3.81- and 2.54-cm (1.5- and 1.0-inch) diameter FRP dowels were installed in the field with 15.24-, 20.32-, 22.86-, and 30.48-cm (6-, 8-, 9-, and 12-inch) spacings. Load calibrated field tests were conducted on these pavements using a West Virginia Department of Transportation truck in 2002 and 2003. FRP dowel bars that were 1.5 inches in diameter were also used for pavement rehabilitation.
