This document specifies a test method to determine the suitability of a soil to be treated with lime and/or hydraulic binders, with regard to volumetric swelling and mechanical strength, within a period not exceeding two to three weeks.

This test can be integrated into the general method of a study of treatment of materials with lime and/or a hydraulic binder, in compliance with standard EN 16907-4.

It is applicable to soils and alternative (or anthropogenic) materials treated with lime and/or hydraulic binders for the construction of embankments and capping layers; in the areas of roads, railways and airports; industrial or commercial platforms; hydraulic works and road foundations.

The results of this test:

— are only valid for the configuration tested (soil, treatment product, dosage);

— are in no case usable for dimensioning a structure including treated materials.

The values currently accepted to define treatment suitability are indicated for information in Annex A.
