trafficked areas.2apparatus2.1plastic container with a capacity of at least 3 l.2.2stirring rod, with a diameter of 20 mm to 30 mm and a suitable length.3procedure3.1all samples of the slurry mixture shall be taken at the slurry mixer discharger. no sample shall be taken until the mixer has been operating at least 30 min and the slurry mixture has a homogeneous appearance.3.2at the time of sampling ensure a full flow discharge of slurry mixture in one steady stream.3.3take the sample by passing the container through the full width of the discharging mixture and obtaining at least 2 l of the mix without overfilling the container.3.4continuously stir the sample until the emulsion has broken to ensure all the aggregate particles remain in suspension.4sampling reportthe sampling report shall contain:a)statement that the sampling has been performed in accordance with this european standard;b)location of sampling;c)date and time of sampling;d)type of slurry surfacing;e)weather
