ASPHALT CEMENT VISCOSITY AND PENETRATION

ASPHALT CEMENTS SUPPLIED TO NEW YORK STATE DURING 1968 WERE SURVEYED, COMPARING PENETRATION AND VISCOSITY. THE ADVANTAGES AND DISADVANTAGES OF VISCOSITY GRADING WERE EXAMINED. OVER 200 SAMPLES OF 85-TO-100 PENETRATION GRADE ASPHALT WERE TESTED TO ESTABLISH THE ACTUAL RELATIONSHIP BETWEEN VISCOSITY AND PENETRATION. ALTHOUGH PENETRATION WAS QUITE UNIFORM, VISCOSITIES IN THE EASTERN PORTION OF THE STATE AVERAGED 50 PERCENT HIGHER THAN IN THE WEST. OVERLAPPING OF THE TWO VISCOSITIES, AS FOUND IN CENTRAL NEW YORK, COULD LEAD TO CONSTRUCTION DIFFICULTIES. /AUTHOR/
