PERMEABILITY COMPACTION CHARACTERISTICS OF BITUMINOUS MIXTURES

A LABORATORY INVESTIGATION TO ESTABLISH A RELATIONSHIP BETWEEN THE COMPACTION CHARACTERISTICS OF BITUMINOUS MIXTURES AND THEIR AIR PERMEABILITY WAS PERFORMED. SEVERAL MIXES OF DIFFERENT AGGREGATE GRADATIONS AND VARYING ASPHALT CONTENTS MEETING OHIO DEPARTMENT OF HIGHWAYS SPECIFICATIONS FOR HIGH-TYPE SURFACE COURSE WERE STUDIED. SPECIMENS OF EACH MIXTURE WERE MADE AT SEVERAL LEVELS OF COMPACTION BY VARYING THE NUMBER OF BLOWS WITH A MARSHALL HAMMER. LABORATORY AIR PERMEABILITY DETERMINATIONS MADE WITH AN AIR PERMEAMETER WERE RELATED TO THE RELATIVE DENSITY OF THE SPECIMENS. METHODS OF CORRECTING FOR VARIATIONS IN AMBIENT TEMPERATURE AND PRESSURE WERE SUGGESTED AND INCORPORATED. SETS OF CURVES SHOWING THE EFFECT OF VARIATIONS OF AGGREGATE GRADATION AND ASPHALT CONTENT ON THE RELATIONSHIP BETWEEN PERMEABILITY AND RELATIVE DENSITY WERE CONSTRUCTED. /NAPA/
