Rapid Pothole Repair In Concrete Bridge Decks, Abheetha Peiris, Issam Harik

Kentucky Transportation Center Research Report

Using traditional methods to repair potholes in reinforced concrete (RC) bridge decks is time-consuming and requires significant manpower and equipment. However, commercially available epoxies and similar materials provide a repair option that does not require saw cutting the deck around the pothole, concrete removal, and replacement. Researchers laboratory tested three epoxies to identify which is best for pothole repairs. Based on assessments of substrate penetration times and set times for epoxy and epoxy mortar, as well as compressive strength gain over time for epoxy mortar, researchers selected Sikadur 52 for static and dynamic bending tests using small-scale beams with simulated …
