Narrative:
After landing the aircraft, was cleared to taxi to the gate. Turn into the gate appeared normal and marshaller gave no off centerline corrections. Upon arrival marshaller said the left main tires had sunk into the ramp while approaching the gate. Appears this ramp is either too narrow or too soft. Callback conversation with reporter revealed the following information: the reporter stated there was no damage to the airplane. Only after parking at the gate did the marshaller inform the pilot that the main gear wheel had sunk into the macadam in the process of turning in to the gate. The captain was following the guidance of the marshaller. The first officer does not have a tiller on his side. The night was rainy and the captain, as is standard procedure, turned out the nosewheel taxi light so it would not blind the marshaller. Therefore, the pilot does not know where the guide-in stripe was relative to his turn in to the gate. The reporter stated he was about 50 hours per month for the last 3 months, and 600 hours per yr for the last 3 yrs in the MD11. He stated the company has not contacted him about any damage to their ramp, but the gate is a tow in gate now.
