IMO, Bloodthirster is an offensive item, so if you can't live long enough to really use that AD, then you're better off getting something tankier. However, BT can be really good for a more passive playstyle (that lifesteal!) I like rushing it on Riven, because it gives her enough sustain to stay in lane and enough AD to really go to town on your lane opponent.

Also, consider Ravenous Hydra for something similar. Probably not for Jayce, but a lot of solo top champs can use RH well too.
