I can tell you that this is commonly called, here in the south, by a
racially-derogatory slang name that I won't repeat for fear of prosecution
in this, our politically-correct age.
It has often been used in the south, but even here you hardly find it used
anymore, if at all. And of course we've hardly ever been concerned with
seismic, although we have a bit of wind to contend with in some areas.
If I were you, I'd consider replacing it.

Subject: Wood Shearwall
I am renovating an existing grocery store here in SLC. The existing
exterior walls are sheathed with "Asphalt Impregnated Fiber Board". Does
anyone know what this is? Does it have a shear value? Or do I need to
replace it all.
While it may be tempting to be generous to an asphalt (impregnated fiber
board), the Wasatch Fault is likely not to be so forgiving. It would be
best to make sure you end up with what the code recognizes as "structural
sheathing" - then you know what it means.
