BS EN 12274-1:2002 – Slurry surfacing — Test methods — Part 1: Sampling for binder extraction

1 Scope
This European Standard specifies a method for sampling of slurry mixtures for extraction tests.
The Standard applies to slurry surfacings for roads, airfields and other trafficked areas.
2 Apparatus
2.1 Plastic container with a capacity of at least 3 l.
2.2 Stirring rod, with a diameter of 20 mm to 30 mm and a suitable length.
3 Procedure
3.1 All 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.
3.2 At the time of sampling ensure a full flow discharge of slurry mixture in one steady stream.
3.3 Take 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.
3.4 Continuously stir the sample until the emulsion has broken to ensure all the aggregate particles remain in www. bzfxw. com

b) location of sampling;
c) date and time of sampling;
d) type of slurry surfacing;
e) weather conditions;
