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.
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.
