BGS sheeting types by state
« on: July 25, 2017, 12:08:09 AM »

I would like to know, which states use what types of sheeting for their BGS?

I know ADOT allows the use of either Type IX or XI.

California uses Type XI. 

Caltrans currently has several active projects to replace illuminated button copy signs with non-illuminated Type XI.

MassDOT normally specifies Type VIII or better, although the current I-90 West Stockbridge to Auburn and Auburn to Boston sign projects specified Type XI (both NFA projects, so it gave them an opportunity to get large scale field experience with the material).  Until recently, Type III or IV was specified for black/yellow or black/white banners on BGS signs, but Type VIII or better is now allowed for these banners as well.

I know when ADOT replaces its older signs with Type IX or XI, illumination is generally removed, although if Type IX is used illumination is retained if located in proximity of a major interchange.

The comparison here might get difficult since some states use different names for their sign sheeting.  Illinois per one of their manuals, uses Type AA, AP, AZ and ZZ.

There should be something in the Illinois materials standards that equates their codes to the ASTM sheeting types.  For now, based on the sign type descriptions, I offer the following translations

AA = Type VII
AP = Type III or IV
AZ = Type VIII
ZZ = Type XI

Anyone out there more familiar with Illinois specifications, feel free to correct me if I've goofed it up

And VII (along with X) are obsolete designations, and are now considered Type VIII.

As far as I know, Type XI is supposed to combine the best traits of both VIII and IX.
