Geotextiles discussed in Part 4G are made essentially from polymer mixtures. Geotextiles are permeable fabric materials used in engineering applications. They can be used to separate, reinforce, filter or drain. They may be used to provide protection to waterproof membranes from puncture by overlying rocks. This document is a guide to enable the selection of an appropriate geotextile for a given situation. It provides information to enable the designer to choose the right type of geotextile and one which is adequate for the design. Construction aspects that need to be considered when using geotextiles are discussed in the Guide to Pavement Technology Part 8.
Edition 1.1 updates the Guide format, and corrects equations A1 (section A.2.1) and A19 (Section A.2.7).
