Brian Collins is listed as the geotechnical engineer on this Denali Park Road Repave deep patch project in Alaska. I am hoping to get some clarification as to the separation/stabilization geotextile. The drawing states Class 1 Type A nonwoven geotextile. AASHTO specs dictate a “Class 1A Enhancement Geotextile” be ,50% elongation which would mean a woven geotextile. Can you please clarify if this is just Class 1 nonwoven, or is this Class 1A Enhancement and a woven?

See FP‐14 Subsection 714.01(a) requirements for Separation and Stabilization Geotextile Class 1, Nonwoven, Type A.
