EN 13286-47:2012 (E) 5 1 Scope This European Standard specifies the test methods for the laboratory determination of the California bearing ratio and immediate bearing index. The tests are appropriate to that part of the mixture up to a maximum particle size of 22,4 mm. When immersion in water is specified as part of the curing of the specimen, this European Standard also includes the determination of vertical swelling of the specimen before the determination of the California bearing ratio. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 1097-5:2008, Tests for mechanical and physical properties of aggregates — Part 5: Determination of the water content by drying in a ventilated oven EN 13286-2, Unbound and hydraulically bound mixtures — Part 2: Test methods for laboratory reference density and water content — Proctor compaction 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 California bearing ratio
ratio used to characterise the bearing capacity of a mixture, determined immediately after compaction, or after a period of curing 3.2 immediate bearing index immediate California bearing ratio test without surcharge 3.3 Proctor compactive effort compactive effort used in the Proctor test described in EN 13286-2 3.4 modified Proctor compactive effort compactive effort used in the modified Proctor test described in EN 13286-2 3.5 curing period of time and storage condition between manufacture and testing of the specimen for the California bearing ratio 4 Principle The relationship between force and penetration is determined when a cylindrical piston of a standard cross-sectional area is made to penetrate a specimen of a mixture, contained within a mould, at a given rate. SIST EN 13286-47:2012



EN 13286-47:2012 (E) 6 The California bearing ratio or immediate bearing index is calculated by expressing the force on the piston for a given penetration as a percentage of a reference force. 5 Apparatus 5.1 Apparatus for specimen manufacture 5.1.1 Proctor mould B with appropriate spacer disc, if required conforming to EN 13286-2. 5.1.2
