ASTM D8189-19

5.1 The tackiness test is designed for quantifying how sticky or non-sticky a material is at a certain temperature. The test should be run at various temperatures expected in the field for tack coat materials. If the results show the residue is tacky at pavement temperatures, the material may not be suitable for applications like less-tracking tack coats and bond coats.

5.2 Determining the temperature that the residue becomes tacky by increasing the temperature in successive testing can give formulators an indicator of performance.

1.1 This test method covers the determination of pull-off force and pull-off work of asphalt binders and emulsified asphalt residue by means of pull-off testing. The tackiness test is conducted using the dynamic shear rheometer (DSR) at one or more temperatures.

1.2 A precision and bias statement for this standard has not been developed at this time. Therefore, this standard should not be used for acceptance or rejection of a material for purchasing purposes.

1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.4 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.

1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
