English term or phrase:hacking out
4.8 Sampling of laid and compacted material by hacking out or sawing out slabs
Wheel cutting machine, capable of cutting to the full depth of the course to be sampled.
Wooden frame, of suitable dimensions.
Plastic foil, approximately 0,02 mm thick.
Wire mesh, for reinforcing.
Wooden plank, of suitable size.
When physical properties are to be measured, take slabs at a suitable ambient air temperature
such that damage and distortion do not occur.
At the locations selected for the removal, delineaEt the slabs by chalk lines in such a way that a strip
of 150 mm width approximately is provided around the slab as a removal slot (see Figure 3).
Expose the slabs in such a way that they will not suffer any damage. In the case of layers which do
not adhere to one another quite as firmly, and which might easily suffer a deformation when being
detached from the lower layer, proceed as follows:
a) once the slabs have been exposed, place a wooden frame around each one which
provides a distance of 50 mm to 60 mm margin around the slab, and project at least 10
mm above the top edge of each slab. Lay a thin plastic foil over each slab and its fram a
gypsum plaster. Spread gypsum onto this foil between the slab and the wooden frame, and
smooth plaster by trowelling at the top edge of the wooden frame (see Figure 4 for details).
Insert a wire mesh into the plaster for reinforcement, if necessary;
