Independent review of MIRAFI® H2Ri wicking geotextile performance: Findings and lessons learned
Authors: Eshan V. Dave, Ph.D., and Elie Y. Hajj, Ph.D.
The role of MIRAFI® H2Ri in improving pavement performance was evaluated through an extended review of available literature from widespread studies (over 35 publications). The contribution of H2Ri was examined in terms of three key actions: moisture management, moisture redistribution and filtration, and mechanical action.
The reviewed studies demonstrated the efficacy of H2Ri across the three key actions, affirming its positive impact on pavement performance and longevity, and moisture management.
The findings from laboratory experiments, field trials, and computational models validated the H2Ri’s ability in enhancing pavement structural capacity, mitigating moisture-related issues, reducing premature repair needs, and promoting overall pavement longevity. An improved resilience to moisture induced stressors is expected for pavements treated with H2Ri.
