One of the tests developed for routine control of asphaltic binder susceptibility to stripping in the presence of water is the Thelen Sphericity Index. This test measures the degree of adhesion of an asphalt to pyrex glass in the presence of water. A tentative relation was found between the sphericity index, as measured by the test, and the percentage of stripping as measured by the dye stripping technique. The method did not provide satisfactory repeatability. Further studies of the various factors affecting the test repeatability were performed. However, these studies did not provide repeatable results and the adhesion test was abandoned.
