The application of geosynthetics in road construction offers numerous benefits, such as extending pavement service life, reducing base course thickness, and enhancing the resilience of weak subgrades. This study focuses on cyclic CBR (California Bearing Ratio) tests conducted on Polish and Romanian soils, reinforced with geosynthetics, to evaluate the development of the resilient modulus under cyclic loading conditions. The cCBR tests were conducted on samples with varying geosynthetic configurations to investigate their influence on performance. Results demonstrated that geosynthetic reinforcement significantly improved the resilient behavior of both soil types, with variations observed depending on the number of reinforcement layers and soil characteristics. Differences between standard and cyclic CBR test setup, such as number of cycles, calculation technique and result interpretation were identified, giving recommendations for a modified testing approach. This research highlights the potential of geosynthetics to improve the cyclic performance of soils, providing insights into their role in enhancing pavement durability.
