Performance of Fiber Reinforced Polymer Patching Binder for Minimizing Reflective Cracking
Several strategies 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. Fiber reinforced patching binder, with or without geo-textile mats, has been used on the joints with varied success. This paper outlines four joint repair strategies, along with technical data on the patch materials and techniques. Performance was measured over the course of 7 years (many seasons and much traffic) following the final overlay of each section. The performance of each pavement is reported in terms of reflected cracks and International Roughness Index (IRI). Ride quality (IRI) is moderate to good, and there is little evidence of reflected cracks coming through. It was believed that fiber reinforced polymer patching binder is a viable option for minimizing and delaying reflective cracks. Performance history indicates that milling off prior AC overlays is not necessary and does not improve the long-term performance.
