ASTM D5361/D5361M-11a
(Practice)Standard Practice for Sampling Compacted Bituminous Mixtures for Laboratory Testing
Standard Practice for Sampling Compacted Bituminous Mixtures for Laboratory Testing
SIGNIFICANCE AND USE
Samples obtained in accordance with the procedure given in this practice may be used to measure pavement thickness, density, resilient or dynamic modulus, tensile strength, Marshall or Hveem stability, or for extraction testing, to determine asphalt content, asphalt properties and mix gradation.
SCOPE
1.1 This practice describes a procedure for removal of a sample of compacted bituminous mixture from a pavement for laboratory testing.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information 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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version

such as carborundum or similar material.

be omitted when only a single sample is to be secured. At any time there is evidence of damage to the edge of the sample due to
the generation of heat caused by friction, a cooling material shall be applied to the cutting tool or to the pavement surface to
minimize sample distortion or other damage.
