METHODOLOGY AND EFFECTIVENESS OF DRAINAGE SYSTEMS FOR AIRFIELD PAVEMENTS
This study indicates that most of the airfield pavements have relatively good surface drainage but slow subsurface drainage. Joint and surface sealing and repair program are not able to keep all surface water out of structural sections. When heavyload pavements are required to carry traffic of heavy planes while the pore spaces are filled with water, the rates of damage are often much greater than when there is no free water present, and load-carrying capacities may be lowered. Most of the heavy-duty pavements have been conservatively designed and show little structural damage, although there are various levels of problems with shrinkage cracks, spalling, "D" cracking, joint deterioration, etc. There appear to be definite engineering and economic advantages with types of subsurface drainage systems that are capable of greatly shortening the length of time that free water can stay in structural sections.
