1.1 To determine the efficiency with which asbestos fibers increase the consistency when mixed into a liquid asphaltic vehicle, relative to fibers chosen as standard.
1.2 This test method is applicable to Quebec Standard Group 7 asbestos fibers as determined by Test Method D 3639.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.4
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.
The objective of the test is to determine what quantity of the fiber under evaluation must be mixed with 100 g of cutback asphalt to give the same penetration as a target penetration.
The target penetration is determined with the same cutback asphalt as used for the test using standard calibrated asbestos fiber.
This test method determines the efficiency with which the asbestos tested will increase the consistency when mixed with a liquid asphalt.
