M/138 - Addendum

This document specifies the characteristics for loose-fill expanded clay lightweight aggregate (expanded clay LWA) products for Civil Engineering Applications excluding the use as thermal insulation in and under buildings which are covered by EN 14063-1. The document covers the use of expanded clay LWA as lightweight fill and insulation materials in embankments for roads, railways and other trafficked areas and as lightweight backfill for structures.
This document also describes the product characteristics and includes procedures for testing, assessment and verification of the constancy of performance (AVCP), marking and labelling.
This document does not specify the required level of a given property to be achieved by a product to demonstrate fitness for purpose in a particular application.

This standard describes the product characteristics and includes procedures for testing, marking and labelling.

This document specifies the assessment of characteristics for loose-fill expanded clay lightweight aggregate products (hereafter as: expanded clay LWA) intended to be used for application in civil engineering works.
This document covers the use of expanded clay LWA as:
-   lightweight fill and insulation materials in embankments for roads, railways and other trafficked areas;
-   lightweight backfill for structures.
This document specifies procedures for assessment and verification of constancy of performance (AVCP) of characteristics of the expanded clay LWA.
This document does not cover the expanded clay LWA:
-   which are intended to be used as thermal insulation in- and under buildings (already covered in EN 14063-1:2004).
