This document specifies the characteristics of metallic and non-metallic geotextiles and geotextile-related products used in the construction of pavements and asphalt overlays and the appropriate test methods to determine these characteristics. The intended use of these geotextiles and geotextile-related products is to fulfil one or more of the following functions: reinforcement, stress relief and interlayer barrier. The use of geotextiles and geotextile-related products is to be considered as a part of an interlayer and asphalt overlay system. This document is not applicable to geosynthetic barriers, as defined in EN ISO 10318. This standard provides for the assessment and verification of constancy of performance (AVCP) of the product to this European Standard including factory production control procedures. This document defines characteristics to be considered with regard to the presentation of performance.
