Abstract:

The use of chemically stabilized subgrades in routine maintenance and new construction of roadways represents an expensive way to address the problem of stabilization and separation from base materials. In 1984 a nonwoven Supac 8NP was installed on secondary state highway SH-131 in Atoka County, Oklahoma, to investigate a more cost-effective means of separation and stabilization. Roadway performance of the geotextile test sections was compared with the traditionally used 610-mm (24-in.) lime-stabilized subgrade control sections, as both the geotextile and the stabilized subgrade were covered by the same pavement structural section. Also evaluated was geotextile survivability and performance after the rigors of construction, the stress of traffic, and aging. Roadway history, fabric and soil sampling and testing, road conditions, and estimation of fabric durability are examined. Geotextile durability is determined by removing the fabric from the roadway and testing the exhumed samples. Data are compared with the original, unaged samples.
