Enhanced Moisture Management of Pavement Systems through Capillary Suction
Moisture-induced distress is one of the primary causes of premature failures of roadways. It is well understood that unsaturated conditions are the driving force in pavement performance. Geosynthetics have been used to provide separation, filtration, reinforcement, and confinement in pavement systems for decades. They have also been used to provide drainage. Previously the main function of drainage relied on gravitational water flow, hydraulic head development, and saturated conditions. The development and ongoing research of an enhanced lateral drainage geotextile (ELDG) provides new alternatives to designers, contractors, and owners in the active management of moisture content within roadways. This paper explains the functioning mechanism of the ELDG system and summarizes the years of research which have culminated in providing designers the ability to quantify the benefits to unpaved roads and flexible asphalt pavements.
