DISCUSSION OF A NEW ADDITIONAL SPECIFICATION FOR ASPHALTIC ROAD OILS

IN A DISCUSSION OF THE SPECIFIC GRAVITY, FLASH POINT, MOISTURE, VISCOSITY, DISTILLATION, DUCTILITY, AND SOLUBILITY, IT IS CONCLUDED THAT THESE TESTS ARE OF NO VALUE IN PREDICTING THE QUALITY OF ASPHALT. QUALITY IS DEFINED AS EMBRACING SUCH PROPERTIES AS EASE OF APPLICATION, THE RAPIDITY AND TENACITY WITH WHICH IT COATS AND ADHERES TO THE AGGREGATE, ITS RESISTANCE TO RUPTURE, CRACKING OR THE ABILITY TO WITHSTAND DEFORMATION WITHOUT FAILURE. IT ALSO EMBRACES THE ABILITY TO RETAIN ITS ORIGINAL CHARACTERISTICS TO RESIST STRIPPING, WEATHERING AND HARDENING. THE QUALITY TEST PROPOSED IS THE DETERMINATION OF THE VISCOSITY INDEX OF THE OILY PHASE OF THE ASPHALT.
