DIN EN 13286-47:2012-07 EN 13286-47:2012 (E) 5 1 Scope This European Standard specifies the test methods for the laborat
34、ory 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 determin
35、ation 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.

39、tive 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
40、 a standard cross-sectional area is made to penetrate a specimen of a mixture, contained within a mould, at a given rate. DIN EN 13286-47:2012-07 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
41、 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 Rammer A or B, conforming to EN 13286-2. 5.1.3 Balance accurate to 0,1 % of mass weighed and capable of weighing u

45、nown to 100 g, an internal diameter of (53 1) mm and an external diameter equal to the diameter of the mould minus 5 mm. NOTE Alternatively half-annular segments may be used. 5.3 Additional apparatus for determination of the California bearing ratio and immediate bearing index 5.3.1 Cylindrical pene
46、tration piston with a diameter of (50 0,5) mm, the lower end of which shall be of hardened steel. 5.3.2 Loading machine with a capacity of at least 50 kN capable of applying the test force through the piston at a penetration rate of (1,27 0,20) mm/min. The machine shall be equipped with a load-indic
47、ating device that can be read to 5 N or less. 6 Test sample for the California bearing ratio and immediate bearing index tests After sieving on a 22,4 mm sieve, approximately 7,5 kg of mixture shall be used for one test and water content determination. The quantity shall be weighed accurately so tha
