39、 For the purposes of this European Standard, the terms and definitions given in EN 58 and the following apply. 3.1 representative sample bulk sample consisting of a specified number of increments purposely taken to represent a specific quantity or area of material NOTE A representative sample is ass
40、umed 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 It may be the whole or part of the bulk or representative sample and should be of sufficient quantity for a
41、ll tests required.

42、s carried out NOTE A number of tests may be necessary to produce a test result. 3.5 test result result obtained by applying the test procedure to a test portion NOTE 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 r

45、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
46、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 may require refrigeration especially for porous asphalt cores. 5.2 Pre-treatment of laboratory samples taken
47、before and during laying 5.2.1 Binder drainage If any binder drainage has occurred, collect and weigh as much of the drained material as possible and record the details. When the laboratory sample has been reduced to a suitable size for testing, add a proportionate representative weighed fraction of
48、 the drained material to the test portion. Record if the drained material can not be collected. 5.2.2 Uncoated aggregate Record the presence of any uncoated or fractured aggregate but do not remove such aggregate. 5.3 Pre-treatment of laboratory samples taken after laying 5.3.1 General If possible,
49、record the average thickness (or thickness if there is more than one course) in accordance with prEN 12697-36:1996 and the presence of any extraneous material. Remove all extraneous material in accordance with the appropriate clause of this European Standard. If complete removal is not possible, this shall be recorded. NOTE In most cases, total removal can only be effected by sawing. 5.3.2 Coated chippings If possible, remove chippings by hand before starting the tests. If removal is not possible (e.g. due to deep embedment), record this and proceed wit
