Abstract:The selection of a geotextile to be used in conjunction with a synthetic core in a drainage layer should be part of the design process. Due to the large number of variables affecting the performance of the drainage layer it may be difficult to evaluate which geotextile would provide the best performance for a particular application. The decision analysis technique described in the paper provides a logical and methodical approach for comparing index or design test data to rank the geotextile in each performance area expected to affect the overall performance of the drainage layer.
