Nonwoven Geotextile Fabrics: Evaluation and Specification for Subdrainage Filtration

摘要

This project developed techniques for evaluating the Flow Capacity (FC) and the Plugging Flow Capacity (PFC) of nonwoven geotextile fabrics. These parameters can be specified for given fabric installations and will provide fabrics of suitable flow capability and filtration potential without excessive plugging. Recommended specifications and test methods for FC and PFC, developed during this study, are included as interim guidelines, to be evaluated and refined through applied use.
