The application of geosynthetic-reinforced asphalt in pavement engineering has gained attention for its potential to improve durability, reduce material usage, and enhance resistance to pavement distresses such as fatigue cracking and rutting. This study explores the feasibility of using prefabricated geosynthetic-reinforced asphalt (PGRA) slabs as a solution for pothole repairs. Eight slabs were fabricated in a laboratory using a bituminous concrete mix of Grade 1 and installed to repair a pothole. Four months after installation, the performance of the repaired section was evaluated through visual inspections and light weight deflectometer (LWD) tests to assess structural response. The findings provide insights into the practicality and effectiveness of PGRA slabs for localized pavement repairs, contributing to the ongoing development of durable and efficient maintenance techniques.
