Standard Test Method for Tackiness of Asphalt Binders and Emulsified Asphalt Residue Using the Dynamic Shear Rheometer (DSR)

Importancia y uso:

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.
