Abstract

A modular element for a bridge or structural bearing having metal plates encased within layers of vulcanized rubber is formed in a press including a lower member with at least one post or pin extending upwardly through corresponding holes in the metal plates. A vulcanized rubber plug is inserted and retained in each hole in the modular element after it is removed from the press.
