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.
Note 2: The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Specification D3666 are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this standard are cautioned that compliance with Specification D3666 alone does not completely ensure reliable results. Reliable results depend on many factors; following the suggestions of Specification D3666 or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.View Less
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.
Note 1: This standard may be used for unconditioned material or material conditioned in accordance with Test Method D2872. The majority of development work on this test method was performed on unconditioned material. The emulsified asphalt residue should never be conditioned.
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.
