• Emphasis on the importance of immediate dewatering scheme. There was clear evidence that significant pavement damage was due to the influence of high water level, therefore there is an urgent need to lower the water level beneath the pavements in both damaged and undamaged areas. No visible damage in some of pavements does not imply that no problem with the water level beneath the pavement. The damage may be insignificant at this moment, but it will accelerate during the raining season. Up to now, it appeared that AOT had not taken the dewatering matter urgently and seriously, and the pavement damage would be worsened when the first heavy rain arrives. It is irresponsible for any AOT staff in charge of the airfield pavement to be idle until major disaster happened, then the consequence would be unimaginable
