specific quantity or area of material

Note 1 to entry: A representative sample is assumed to have the same composition as the material

sampled, within the limits of precision associated with the method of sampling.
3.2
laboratory sample
sample despatched to the laboratory

Note 1 to entry: It can be the whole or part of the bulk or representative sample and sufficient quantity

for all tests required.
3.3
test portion

part of the laboratory sample to be used for a specific test procedure to produce a single test

result
3.4
test specimen
part of the test portion on which a single test is carried out
Note 1 to entry: A number of tests might be necessary to produce a test result.

3.5
test result
result obtained by applying the test procedure to a test portion

Note 1 to entry: When the test procedure is required to be carried out on more than one test specimen,

the test result will be calculated as the mean result of a number of determinations.

4.2 Ruler.
4.3 Circular saw, capable of cutting stone.
4.4 Oven, conventional or microwave.
4.5 Stopwatch.
4.6 Metal tray (optional).

4.7 Sample splitter in accordance with EN 932-1 (such as that shown in Figure 1), optional.

4.8 Shovel.
4.9 Container.
5 Preparation of laboratory samples of bituminous mixtures
5.1 Preliminary inspection and storage
5.1.1 On receipt of the laboratory sample inspect it and record its condition.

5.1.2 If a slab or a core cut from compacted material is to be stored prior to examination or

separation of courses, take care so as to minimize deformation or deterioration of the material.

Store slabs on a clean, hard, flat surface, preferably out of direct sunlight, with the final rolled

surface at the bottom.

NOTE Cores of well compacted materials made with high viscosity binders will normally keep well

standing vertically upside down on a clean bench in a cool room, but cores cut from less stable materials

might require refrigeration especially for porous asphalt cores.
