The range includes the optimum water content at which the maximum dry densityfor the specified degree of compaction is obtained. The relationship between dry density and water content isdescribed in EN 13286-1.5 Apparatus5.1Cylindrical, corrosion resistant, metal mould, with an internal diameter of (152,0 ± 0,5) mm, an internaldepth (127,0 ± 1,0) mm and a minimum wall thickness of 5,0 mm. The internal faces shall be smooth, clean and drybefore use.NOTECylindrical mould and collar extension is shown in Figure 1.5.2Detachable baseplate and removable extension piece, to fit mould.5.3Electrically powered vibrating hammer, conforming to the performance check in annex A.NOTEA vibrating hammer with a power consumption of at least 600 W, an operating frequency between 25 Hz and 60 Hz,and fitted with a suitable safety circuit breaker may be suitable.SIST EN 13286-4:2004

The sample submitted to the laboratory shall have a mass ofat least 40 kg.Determine the particle size distribution of the laboratory sample, using the procedures described in EN 933-1,including the 40 mm and 20 mm sieves.NOTEThis test method is suitable for use if the particle size distribution conforms to the grading envelope in Table 1.Table 1 — Particle size distributionTest sievePercentage passing40 mm90 to 10020 mm70 to 100Determine the water content of a test portion taken from the laboratory sample using the procedures described inEN 932-2 and EN 1097-5.6.2 Preparation of the test portionRemove all of the particles retained on the 40 mm test sieve from the remainder of the laboratory sample. Use thesieving procedures described in EN 933-1, without first washing and drying the sample. If necessary, sieve in partsto ensure that the test sieve is not overloaded.Weigh and record the mass of the particles retained on the 40 mm sieve.If the laboratory sample contains 5 % or less, by mass, of particles retained on the 40 mm test sieve, the resultingmodified sample shall be considered as the test portion.If the laboratory sample contains more than 5 % but less than 10 %, by mass, of particles retained on the 40 mmtest sieve, further modify the sample by adding an equal mass of similar material which passes the 40 mm testsieve but is retained on the 20 mm test sieve. The resulting modified sample shall be considered as the testportion.6.3 Preparation of the test specimensSubdivide the test portion into five or more test specimens, each of about 6 kg, using the procedures described inEN 932-2. Weigh and record the mass of each test specimen.Using the water content of laboratory sample, calculate the required amount of water which needs to be added to,or lost from, each test specimen to give a suitable range of nominal water contents.The range of nominal water contents selected shall be such that at least two values lie either side of the value atwhich the laboratory dry density is expected to occur.NOTEIncrements of 1 % to 2 % are suitable.If a test specimen initially contains more water than is required for compaction at a selected nominal water content,allow the test specimen to dry to the desired nominal water content, and mix thoroughly.SIST EN 13286-4:2004
EN 13286-4:2003 (E)87 Procedure7.1 CompactionWeigh the mould with the baseplate and extension attached. Record the mass m1 to the nearest 5 g. Measure andrecord the height H of the extended mould, to nearest 0,5 mm.Place the assembly on a heavy solid base with a mass of not less than 50 kg.NOTE 1A concrete floor or concrete plinth are suitable.Place some of the first test specimen into the mould such that, when compacted, it occupies about one third of theheight of the mould body. Place the foot of the tamper attachment on the specimen and compact with the vibratinghammer for (60 ± 2) s.During compaction, apply a steady downward force on the hammer so that the tamper attachment does not bounceon the compacted specimen and the total downward force on the test specimen, including the mass of the hammer,is between 300 N and 400 N.NOTE 2The application of the necessary pressure to achieve the required downward force should be checked by theoperator before the test starts. Push the hammer – without vibration – against the load pan of a suitable platform balance until amass of 30 kg to 40 kg is indicated.Place a second similar volume of the first test specimen into the mould and repeat the compaction stage. Add athird volume of the test specimen so as to give an expected compacted volume which will conform to therequirements for height set out in 7.2, and compact again.7.2 MeasurementRemove any loose material lying on the surface of the test specimen around the side of the mould. Lay thestraightedge across the top of the extended mould. Measure down from the straightedge to the compacted surfaceof the test specimen, to the nearest 0,5 mm.Take readings at four points spaced evenly over the surface of the test specimen, at least 15 mm from the side ofthe mould. Using the previously measured internal height of the extended mould H calculate the mean height h ofthe test specimen, to the nearest millimetre.If the mean height of the test specimen h is less than 127 mm or more than 133 mm, reject the compacted testspecimen and repeat 7.1 and 7.2 using the remainder of the test specimen. Make suitable adjustments to theamount used, until a compacted specimen of the required height is obtained.Weigh the mould, compacted test specimen, extension collar and base plate. Record the mass m2 to the nearest5 g.Remove the compacted test specimen from the mould and determine its water content using the proceduresdescribed in EN 1097-5. Discard any of the test portion which remains.7.3 Further test specimensRepeat the procedures described in 7.1 and 7.2 for the remainder of the test specimens.SIST EN 13286-4:2004
