Narrative:

At PM30 local, we were taxiing east on taxiway B. Near A18, I departed the taxiway and entered the area between taxiway a and taxiway B. As soon as I realized we were off the taxiway, I stopped and called for a guideman to watch as we returned to the taxiway. The pavement was wet and the markings hard to see in the glare of the lights. I thought I had the nosewheel on the centerline. I am still not sure how I ended up where I did. Note the difference between commercial page 20-9 and 20-9B. 29-9 shows a right turn at A18 and 20-9B does not. Postflt inspection revealed no damage. Callback conversation with reporter revealed the following information: the commercial airport chart 20-9B is an expanded center/terminal section of chart 20-9. The reporter was navigating with chart 20- 9B entering his gate. The reporter taxied into the area, painted green, between A18 and A19. This area, along with 34 others nearby, used to be txwys and are load bearing surfaces. There are painted roadways for service vehicles running through the green painted areas. Chart 20-9B does not show a slight right turn to go around the area. The area is marked with taxiway lights that are on stanchions about 1 ft above surface level. Bright lights from the international terminal can shine on the wet pavement of the islands making markings and the green paint invisible. The reporter called for a wing walker as he did not know if he had, or might, hit a taxiway light or pick up trash that might be in this unswept area.
