Standard Test Method for Toughness and Tenacity of Bituminous Materials
Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
1.1 This test method describes the procedure for measuring the toughness and tenacity of bituminous materials. Typically, the test method has been used to characterize elastomer modified asphalts, although values for toughness and tenacity may be obtained for any type of polymer-modified or non-modified asphalt.
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.
1.2 The values given in SI units are to be regarded as the standard. The values given in inch-pound units in parentheses are for informational 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.
Significance and Use
This test method is useful in confirming that an asphalt cement has been modified with a material that provides a significant elastomeric component. Elastomer modified asphalts can be characterized by their ability to be stretched to a large elongation while at the same time resisting further stretching. Toughness and tenacity are two parameters for measuring this ability.
