چکیده انگلیسی
Several strategies with Fiber Reinforced Polymer Patching Binder (FRPPB) have been used for the repair of jointed concrete pavements. The primary goal of such repairs is to minimize and delay the reflective cracks through a subsequent overlay. The same material has been used successfully in various districts to repair spalls in continuously reinforced concrete pavement, to fill voids at longitudinal joints, and to repair bridge approach slabs that have significant movement. Field results from US59 indicate that FRPPB can be used effectively to retard reflected cracks in AC overlays over JCP. The responsible engineers are very pleased with the FRPPB performance, as the section has provided excellent ride quality over the last 9 years and has required zero maintenance. Since most movements that cause reflected cracks are near the transverse joint, removing a slot at the transverse joint and filling it with FRPPB has proven to be a viable option for mitigation of reflected cracks. To date, the oldest spall repair has been in service for over 8 years, and is still performing well. FRPPB is able to adhere and adapt to volume changes in the surrounding concrete pavement, and conforms to settled or moving concrete slabs without any crack development.
