    Behaviour of the Pavement Subgrade Reinforced with Coir Geocells Under Repeated Loads
    (Springer, 2025) Raveendran, D.; George Paul, A.; Hassan Noorudheen, F.; Bilal, M.; Kolathayar, S.
    This study investigates the performance of natural coir geocell–reinforced sandy subgrades through repeated plate loading tests. Key parameters were evaluated under simulated traffic loading, including load-settlement behaviour, elastic rebound, and cumulative permanent deformation (CPD). Coir geocell reinforcement reduced CPD by 42%, improved resilient modulus by nearly 67%, and achieved a traffic benefit ratio (TBR) of 23 at a rut depth of 33 mm. Mechanistic-empirical pavement analysis demonstrated a 40% reduction in base course thickness and a 22% reduction in overall granular layers for pavements designed for 10 million standard axles. These results demonstrate the effectiveness of three-dimensional coir geocells in improving subgrade resilience under repeated loading conditions. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2025.
