(Practice)Standard Practice for Sampling Bituminous Paving Mixtures
Standard Practice for Sampling Bituminous Paving Mixtures
SIGNIFICANCE AND USE
General:
Sampling is equally as important as the testing, and the sampler shall take every precaution to obtain samples that will yield an acceptable estimate of the nature and conditions of the materials which they represent.
Samples for the development of preliminary data are obtained by the party responsible for the development of the data. Samples for control of the product at the source of manufacture or storage, or at the site of use, are obtained by the manufacturer, contractor, or other parties responsible for accomplishing the work. Samples for tests to be used in acceptance or rejection decisions by the purchaser are obtained by the purchaser or his authorized representative.
This standard shall not be used for the sampling of compacted bituminous paving mixtures. shall be used.
SCOPE
1.1 This practice covers sampling of bituminous paving mixtures at points of manufacture, storage, delivery, or in place.
1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are provided for information purposes only.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
