VIBRATORY COMPACTION OF ASPHALT CONCRETE PAVEMENTS

THERE ARE SEVERAL MODELS OF VIBRATORY ROLLERS THAT CAN MEET THE CALIFORNIA DIVISION OF HIGHWAYS' 95 PERCENT RELATIVE COMPACTION REQUIREMENT FOR ASPHALT CONCRETE PAVEMENTS. USE OF VIBRATORY ROLLERS PRODUCED LOWER ASPHALT CONCRETE PERMEABILITIES THAN THOSE OBTAINED USING PNEUMATIC ROLLERS, EITHER PARTIALLY OR EXCLUSIVELY. PAVEMENT SURFACE UNDULATIONS WILL NOT RESULT IF VIBRATORY ROLLERS ARE OPERATED AT A FREQUENCY ABOVE 1800 VPM. THE DOUBLE VIBRATORY DRUM ROLLERS TESTED TO DATE HAVE PROVEDED HIGHER ASPHALT CONCRETE DENSITIES WITH FEWER COVERAGES THAT ALL THE OHTER TYPES OF COMPACTORS TESTED. COMPATIBLE COMBINATIONS OF AMPLITUDE, FREQUENCY, AND ROLLER WEIGHT MUST BE PROVIDED FOR SATISFACTORY COMPACTION TO BE ACHIEVED. /DOT/
