Mirafi Mirafi RS580i US Fabric Equivalent is US HT500

US HT500 is manufactured using high tenacity polypropylene yarns that are woven to form a dimensionally stable network, which allows the yarns to maintain their relative position. US HT500 resists ultraviolet deterioration, rotting, and biological degradation and is inert to commonly encountered soil chemicals. US HT500 meets the following M.A.R.V. values except where noted:

Mirafi RS580i is a specially designed geosynthetic that integrates the key performance characteristics to maximize performance. Extensive performance testing has been performed per AASHTO and FHWA guidelines to validate performance for both paved and unpaved roads. This data sheet for Mirafi RS580i is provided for comparison purposes only.
