Narrative:

At night with light rain and poor visibility of taxi lines, the captain turned from delta taxiway attempting to join bravo. We became unsure of our position between alpha and bravo. It appears we were on paved concrete slightly encroaching the pad between A18 and A19. No aircraft damage. No taxi light damage. We secured a tug and pushed back a few ft to rejoin the taxiway. As soon as our position became unclear the captain stopped the aircraft and called for a tug. I was looking at the airport taxi diagram as the right turn was made. I cleared to the right then looked back to the chart. New taxiway markings and poor visibility contributed.
