A quantified approach to the functional longevity of Geosynthetic Rolled Erosion Control Products (GRECPS)

摘要

Geosynthetic Rolled Erosion Control Products (GRECPs) have been utilized for decades in a multitude of applications to mitigate erosion resulting from land disturbance in civil construction projects. GRECPs vary from one type to another, ranging in performance and design life due to their composition and intended purpose. The coverage and durability of the GRECP are fundamental properties that can predict performance and fitness for use. Both coverage and durability will degrade over the design life of the GRECP to the point that fitness for use is unacceptable for the intended application. A standard approach is needed to quantify this material degradation over time. Through this analysis, the degradation of the GRECP’s durability and coverage is predicted over time, field validated, and compared to their respective functional thresholds. The time at which the GRECP’s durability or coverage reduces below the established functional thresholds is known as the GRECP’s functional longevity.
