EN 13286-50:2004 (E) 5 1 Scope This document specifies a test method for making cylindrical specimens of hydraulically bound mixture to a predetermined density using Proctor equipment or vibrating table compaction. The method is appropriate for mixtures, or that part of
29、 a mixture, containing aggregate up to a maximum size of 31,5 mm. 2 Normative references The following referenced documents are indispensable for the application of this document.

32、ound mixtures by compacting the mixture into a Proctor mould of known volume using either Proctor rammer compaction or high frequency vibration table until a predetermined density is achieved 4 Principle Cylindrical test specimens of the mixture are prepared using Proctor moulds conforming to EN 132
33、86-2. The mould is filled with the mixture in a specified manner and the mixture is compacted to a predetermined density by a Proctor rammer conforming to EN 13286-2 or by vibrating table conforming to EN 13286-5. After compaction, the specimens are stored, moulded or demoulded, at a specified tempe
34、rature, moisture condition and period of time until required for testing. 5 Dimensions of the specimens Specimens shall conform to the dimensions given in Table 1.

35、00 1 120 1 16 a2 150 1 120 1 31,5 a or 22,4 mm on the basis of experience 6 Apparatus 6.1 Moulds, conforming to EN 13286-2. The mould size shall be selected from Table 1. The moulds shall have extension collars not less than 100 mm high to facilitate filling. NOTE To facilitate demoulding, the use o
36、f split moulds may be appropriate. 6.2 Rammers, conforming to EN 13286-2. 6.3 Vibrating table, conforming to EN 13286-5. A surcharge plug of a suitable mass (usually up to 12 kg) shall be used. The surcharge plug shall fit inside the extension collar and shall have gradations to judge that the requi
37、red height of the specimen is achieved. NOTE The weight of the surcharge depends on the nature of the material and the size of the mould. 7 Procedure 7.1 Mixture Calculate the mass of the mixture required using the following formula: + = 100 1 d w V m where m is the mass of the specimen, in grams (g
38、); V is the volume of the specimen, in cubic millimetres (mm 3 ); dis the dry density of the specimen, in megagrams per cubic metre (Mg/m 3 ); w is the water content of the dry mass of the mixture, in percent (%). NOTE The values of dry density and water content used in the formula will vary accordi
39、ng o experience and practice. For example, the values may correspond to the Proctor density and the optimum water content or optimum water content 1 %. EN 13286-50:2004 (E) 7 7.2 Compaction by rammer Prepare and compact the specimen in accordance with EN 13286-2, selecting the combination of mould a
40、nd rammer to achieve the required density. Choose the numbers of blows for each layer such that the required density is achieved throughout the depth of the specimen. Before the next layer is added, scarify the previously compacted layer to achieve adhesion between the layers. NOTE To determine the
41、number of blows, pre-tests may be necessary. The density of each specimen shall not deviate by more than 0,02 Mg/mm 3from the required density. Calculate the density using the real volume of the specimen. 7.3 Compaction by vibrating table Place the total quantity of mixture into the mould using the
42、extension collar. During filling, tamp the material gently and uniformly using a tamper. Place the surcharge plug on the top and compact the mixture using vibration until the required height of specimen is achieved. The density of each specimen shall not deviate more than 0,02 Mg/mm 3from the requir
43、ed density. The density of the specimen shall be calculated using the measured dimensions of the specimen. 8 Storage After hardening sufficiently but not sooner than 20 h after compaction, demould the specimen. Prior to demoulding, the specimen shall be maintained at a temperature of (20 5) C withou
44、t loss of moisture. After demoulding, specimens shall be stored vertically, preventing loss of moisture, at a temperature within 2 C of the specified temperature, for the time specified in the relevant mixture document. 9 Test report The test report shall include the following information: a) refere
45、nce to this document; b) type of mixture; c) origin of the mixture; d) preparation of the mixture where necessary; e) method of compaction (rammer, vibrating table); f) if applicable the mould and rammer used; g) the mass, water content and dry density of the specimen immediately after compaction; E
