THE EFFECT OF THE MIXING TEMPERATURE ON THE PHYSICAL PROPERTIES OF AN OIL ASPHALT IN A SHEET ASPHALT MIXTURE

THIS PAPER DESCRIBES AN INVESTIGATION WHICH WAS UNDERTAKEN AT LOUISIANA STATE UNIVERSITY TO DETERMINE THE EFFECT OF THE MIXING TEMPERATURE ON THE PHYSICAL PROPERTIES OF AN OIL ASPHALT USED IN A SHEET ASPHALT SURFACE. THE HOT MIXING OF ASPHALT AND MINERAL AGGREGATE CAUSES CHANGES IN THE PHYSICAL PROPERTIES OF THE ASPHALT. THE PENETRATION AND DUCTILITY OF THE ASPHALT ARE LOWERED AND THE SOFTENING POINT IS INCREASED. THE EXTENT OF THESE CHANGES IS EFFECTED BY THE TEMPERATURE OF THE HEATED CONSTITUENTS AT THE TIME OF MIXING. THE PAPER DESCRIBES THE MATERIALS, THE PREPARATION OF THE MIXTURES, THE METHOD OF EXTRACTION AND RECOVERY AND REPORTS THE RESULTS OF TESTS ON THE ORIGINAL ASPHALT AND THE RECOVERED BITUMEN.
