Approximately one fifth of the mixedsample is filled into the mould and levelled and then the increment is tamped uniformlyover the surface of the increment. Tamping is executed by dropping the hammer 25 timesthrough the guide pipe, 0.2 m each time. The performance is repeated for all five layers.When the last layer has been tamped the extension piece is removed and the sample islevelled off along the brim of the mould. When the weight of the cylinder with thetamped sample has been determined, the cylinder is emptied, the sample is dried and theweight is determined.The test then is repeated for the other samples with different moisture contents.I:\<strong>MSC</strong>\<strong>85</strong>\<strong>26</strong>-Add-2.doc
