GSE RoaDrainTM Prevents Water Accumulation in
Pavement Structure

Background

Near the completion of construction, which included a sub cut, imported fill, dense grade aggregate and asphalt base course, significant deformation and rutting over a portion of the roadway surface began to occur. Movement could be seen and felt underfoot of what had been stable just a few days earlier. Exploratory excavation revealed pockets of perched water just a few inches below the original excavation. The problem developed only after the placement of the asphalt base course, an impermeable layer. Prior to that, water vapor migrating upward through the section would evaporate upon nearing the surface. With the introduction of the impermeable asphalt, the water vapor began to accumulate in the structural layers, soon saturating and greatly weakening the section.
