DETERMINATION OF SPECIFIC GRAVITY OF BITUMINOUS CONCRETE MIX FOR FIELD DENSITY CONTROL
THIS TEST METHOD IS INTENDED AS A FIELD METHOD OF DETERMINING THE SPECIFIC GRAVITY OF BITUMINOUS CONCRETE MIX WITHIN THE ACCURACY NECESSARY FOR FIELD DENSITY CONTROL OF PAVEMENT COURSES. THE APPARATUS CONSISTS OF THE FOLLOWING: (1) A TORSION BALANCE OF 2 KILOGRAM CAPACITY SENSITIVE TO 0.10 GRAM AND A SUITABLE SET OF WEIGHTS, (2) A VOLUMETER HAVING A SAMPLE CHAMBER OF 1350 CC CAPACITY AND A SECONDARY CHAMBER OF 675 CC CAPACITY, (3) ALUMINUM INSERTS 4 INCHES IN DIAMETER, 5 EACH AT 200 CC VOLUME, 1 AT 100 CC VOLUME AND 1 AT 50 CC VOLUME, (4) A HAND PUMP SUITABLE FOR PRESSURIZING SAMPLE CHAMBER OF VOLUMETER, (5) A MERCURY PRESSURE GAUGE (OPEN MANOMETER TYPE) CALIBRATED FROM 0 TO 40 INCHES, AND (6) OINTMENT CANS 4 INCHES IN DIAMETER 3 INCHES DEEP PERFORATED EVERY 1/2 INCH WITH 1/8 INCH HOLES ON BOTTOM, SIDE AND TOP.
