DURABILITY OF PAVING ASPHALT-PART III, EVALUATION OF THE THELEN SPHERICITY TEST FOR MEASURING THE ADHESION CHARACTERISTICS OF PAVING GRADE ASPHALTS IN THE PRESENCE OF WATER

THE THELEN SPHERICITY INDEX 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 AND THE PERCENTAGE OF STRIPPING AS MEASURED BY THE DYE STRIPPING TECHNIQUE. HOWEVER, THE ADHESION TEST WAS ABANDONED DUE TO UNSATISFACTORY REPEATABILITY.
