Applicability of Modified Vialit Adhesion Test for Seal Treatment Specifications

The objective of this paper is evaluation of the Vialit Adhesion Test and its potential for use within performance oriented specifications for seal treatments. Multiple aggregates and emulsions are evaluated with existing test methods alongside evaluation with modified equipment and methods. The results indicate the current test tray is inadequate and that a thicker tray provides better results. Conditioning that incorporated either freeze times between 4 to 8 hours and/or freeze thaw cycles were also found to be improvements to the current conditioning methods. The specified mass of the steel spheres used during the test may be too restrictive in that more economical spheres were tested and did not show differences in aggregate loss.
