For Separation / Stabilization The expected life of paved roads and parking lots is extended with a Geotex woven geotextile by permanently separating the subgrade from the aggregate. Geotex "ST" series of woven geotextiles can reduce aggregate thickness in unpaved roads by as much as 50%.
GEOTEX 250STis a woven polypropylene geotextile containing heavy woven tape/fibrillated yarns produced by Propex, and will meet the following Minimum Average Roll Values (MARV) when tested in accordance with the methods listed below. These characteristics make GEOTEX 250ST ideal for the construction of embankments over soft soils, steepened slopes, and modular block and/ or wrapped-face retaining walls. The geotextile is resistant to ultraviolet degradation and to biological and chemical environments normally found in soils. GEOTEX 250ST conforms to the property values listed below1, as well as meets the requirements set forth by AASHTO M-288/NTPEP (Geotextile Specification for Highway Application). Propex performs internal Manufacturing Quality Control (MQC) tests that have been accredited by the Geosynthetic Accreditation Institute - Laboratory Accreditation Program (GAI-LAP).
