EN 13286-52:2004 (E) 5 1 Scope This document specifies a test method for making specimens of hydraulically b

28、ound mixture to a predetermined density and water content by vibrocompression compaction. This document is appropriate to mixtures, or that part of a mixture, containing aggregate up to a maximum size of 31,5 mm. This method is not applicable to mixtures with a high proportion of fines. 2 Terms and

29、definitions For the purposes of this document, the following term and definition applies. 2.1 vibrocompression compaction method of compaction of a laboratory specimen by the simultaneous application of horizontal vibration and light axial compression 3 Principle The mixture is placed in a mould of

30、a given volume. The mixture is compacted with a combination of horizontal vibration and vertical axial pressure. 4 Dimensions of the specimens 4.1 Cylindrical specimens Specimens shall conform to the dimensions given in Table 1. Table 1 Dimensions of the specimen Column 1 2 3 Line Diameter, d mm Hei

32、e 1 Shape and dimension of a tensile test specimen 5 Apparatus 5.1 Moulds 5.1.1 Moulds, made from rigid materials, e.g. plastic or similar, with a volume accuracy of 1,5 % of the nominal volume of the specimen. 5.1.2 Moulds shall be tubes to which caps can be attached to cover each end of the specim

33、ens after compaction in order to prevent loss of moisture during storage. 5.1.3 Moulds for cylindrical specimens (see Figure 2) shall be cut on one generatrix to allow slight opening of the mould in order to remove the specimen after setting. 5.1.4 Moulds for direct tensile testing shall be capable

34、of producing cylindrical specimens with a cross section shown in Figure 1 and shall be split on two opposite generatrix in order to remove the specimen after setting. 5.2 Compaction apparatus (see Figure 2) 5.2.1 Cylinder, to stiffen the mould and lengthen the top end of the mould to allow introduct

35、ion of the mixture before compaction. 5.2.2 Plate, to close the bottom of the mould. 5.2.3 Vibrator, to apply a horizontal vibration to the mould and the mixture with a frequency of 100 Hz and an amplitude between 0,8 mm and 1 mm. The vibration shall be sufficient to compact the specimen to the requ

36、ired density within 90 s using a pressure on the mixture not greater than 0,5 MPa. 5.2.4 Piston, to apply an increasing vertical pulse pressure on the mixture during compaction. EN 13286-52:2004 (E) 7 Key 1 piston 2 cylinder to stiffen the mould 3 cylinder mould 4 mixture to be compacted 5 plate to

37、close the bottom of the mould 6 vibrator Figure 2 Principle of vibrocompression apparatus 6 Procedure 6.1 Place the mould in the cylinder and close the bottom of the apparatus by means of the plate. 6.2 Introduce the mixture into the apparatus. The mass of the mixture to be introduced into the appar

38、atus shall be measured to an accuracy of 1 % and is given by the following formula: () 100 100 000 1 d w V m + = where m is the mass of the mixture to be introduced in the mould, in grams (g); V is the volume of the specimen, in cubic millimetres (mm 3 ); dis the dry density of the specimen, in mega

39、grams per cubic metre (Mg/m 3 ); w is the water content of the dry mass of the mixture, in percent (%). EN 13286-52:2004 (E) 8 6.3 Introduce the piston into the apparatus so that it is contact with the top surface of the uncompacted mixture. At this stage the mixture is only partially contained with

40、in the mould. 6.4 Simultaneously, apply the horizontal vibration to the cylinder and, using the piston, an increasing pulsed vertical pressure axially to the mixture. Stop the compaction when the mixture is completely contained in the mould. If the time of compaction exceeds 90 s, then modify the ta

41、rget density or the water content of the mixture and repeat the procedure. 6.5 Remove the specimen with its mould after compaction. Ensure that the operation is carried out smoothly. Fit the caps and seal with adhesive tape to prevent loss of moisture from the specimen. NOTE 1 To facilitate the rear

42、rangement of the aggregate during compaction, only a very light pressure is applied to the mixture for 2/3s the duration of the compaction. For the final 1/3, the pressure is increased to achieve the full compaction. NOTE 2 The duration of compaction depends on the friction of the aggregate in the m

43、ixture and the density to be achieved. 7 Storage Specimens shall be stored in their moulds with caps attached vertically, preventing loss of moisture, at a temperature within 2 C of the specified temperature, for the time specified in the relevant mixture document. 8 Test report The test report shal

44、l include the following information: a) reference to this document; b) type of mixture; c) origin of the mixture; d) preparation of the mixture where necessary; e) mass, water content and dry density of the specimen immediately after compaction; f) storage conditions of the specimen; g) any deviatio
