GEOTEXTILES HELP STABILIZE RESERVOIR FLOOR

The article describes how the entire floor of the Allegheny Reservoir in Warren, Pennsylvania was resurfaced and resealed. The subgrade stabilization and resurfacing the 74-ft deep basin floor had to be completed during a 5 week period. A portion of the floor was constructed of cold-mix asphalt which had become saturated. The design utilized a geotextile in order to improve the bearing capacity of the subgrade. An elongation factor of 70 % was specified for the geotextile so it could conform to irregularities in the subgrade, preventing puncture during and after installation. A burst strength of 400 psi was specified to provide a stable subgrade in order that the cement/aggregate base could be compacted to the required density atop the subgrade. Details of the installation are described.
