1   Scope This document defines the principle and the methods for the determination of the “degradability coefficient” of rocky material. The degradability coefficient I DG distinguishes the behaviour of certain rocky material and is used to show the change in the geotechnical characteristics (particle size, clay content, plasticity, etc.) in relation to the characteristics seen immediately following excavation. Changes in the particle size occur due to the combined action of climatic or geohydrological elements (frost, soaking-drying cycles) and mechanical stress to which it is subjected. In the case of degradable rocky material, this leads to a fairly significant and continuous reduction in the mechanical and geometric characteristics of the works in which they are used. The two methods developed in this document for the determination of I DG are not equivalent. The results obtained by this document refer to the method used.

1   Scope This document defines the principle and the methods for the determination of the “fragmentability coefficient” of rocky material. The fragmentability coefficient I FR distinguishes the behaviour of certain rocky material and is used to show the change in particle size from the moment that the material is excavated through to its subsequent implementation and in certain cases during its whole service life. Changes in the particle size occur due to the structural resistance of the rock being unable to support the mechanical stress to which it is subjected during its implementation and use.

1   Scope This document describes the reference method for the determination of the methylene blue value ( V BS ) in soils and rocks for earthworks. The test is based on measuring the quantity of methylene blue that can be adsorbed by the material suspended in water. This quantity of adsorbed methylene blue is reported by direct proportionality to the 0/50 mm ground. The soil blue value is directly related to the specific surface area of the soil particles or rocky material. NOTE The V BS test uses common equipment and calibration as the methylene blue test MB for aggregates (EN 933‑9), but it applies to another granular fraction (5 mm for V BS and 2 mm for MB, respectively). Thus, the results obtained between the two tests cannot be compared in the general case.
