Abstract: Work conducted at the Corps of Engineers research laboratories has shown that subsurface pavement layers are virtually impermeable. The impermeable layers become saturated and remain saturated for virtually the life of the pavement. Saturation weakens subsurface layers and causes early deterioration of pavements. In order to reduce pavement deterioration caused by saturated subsurface layers, criterion has been established for the use of drainable subsurface layers. This criterion is contained in Engineering Technical Letter 1110-3-435. At Fort Campbell, Kentucky, a vehicle maintenance facility parking lot was constructed with a drainable base course. The expected benefits of constructing a pavement with a drainable base include improved pavement performance by reducing problems associated with saturated subsurface layers. Problems associated with saturated subsurface layers include pumping, erosion, subgrade weakening, frost heave, and freeze/thaw damage.
