| Objectives of this study are to evaluate FRP dowel bars as load transferring devices in JPCP under HS-25 static and fatigue loads and compare 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 has been carried out in terms of maximum bending deflection, relative deflection and bearing stress of dowels.; Laboratory tests conducted in this study include static and fatigue load application corresponding to HS-25 load and 1.5 times HS-25 load on concrete slabs (11&inches; and 12&inches; depth) with 1.5&inches; and 1.0&inches; steel and FRP dowels at different spacings (12&inches;, 6&inches;).; Theoretical calculations are provided through different examples for JPCP with FRP and steel dowels by varying dowel diameter, spacing, dowel material properties, joint width, and base material properties.
