LONG-TERM PERFORMANCE USING SEPARATION GEOTEXTILES

This article analyzes the long term performance of roadways that use separation geotextiles. It lists the detrimental effects of saturation in pavement systems, then explains AASHTO pavement design methodology for free-draining aggregate bases. Geotextiles function as a separation in the base layer, the article explains, and requirements to achieve the separation functions such as retention, permeability, and survivability are listed. Existing performance metrics for geotextiles are also discussed, detailing lab studies and research limitations. A cost/benefit determination section explains techniques for performing a cost/benefit analysis.
