neoprene bearing pad

[jie5]

We received a set of construction documents for a bridge that we are detailing, there is a designation "1/4" neoprene bearing pad (M9.16.2)" referring to a pad below the base plate of the guide rail post. Does anyone know what the M9.16.2 designation means?

Quick google search...MassDOT? Or maybe another state that starts with "M"?

Its the first link on the above google search...it refers to DOT spec M9.16.2 in the notes
