One More Thing On Bridge Bearing

My GUESS is that continuous welding builds up enough heat to cause the adhesive bond to fail, and the lip would then retain the bearing in place?

Recessed defines the condition. Lipped is confusing and redundant and, to me, would indicate that you are adding material to create the lip. Recess means removal of material to create the, "recess".

This material has got many ，as u pointed out , reduntant words, that might cause trouble for translators but not necessarily end-users. Well, i have highlighted those confusing places ( which is my standard practice ) and hope there is no info that might "get lost in translation".
