COMPACTION OF ASPHALTIC-CONCRETE PAVEMENT WITH HIGH- INTENSITY PNEUMATIC ROLLER

TO INCREASE THE SERVICE LIFE OF ASPHALTIC-CONCRETE PAVEMENT AND ELIMINATE OR MINIMIZE RUTTING, IMPROVEMENT IN COMPACTING PROCEDURES SEEMS WARRANTED. THE RESULTS DISCUSSED HEREIN EMPHASIZE THE IMPORTANCE OF COMPACTING ASPHALTIC- CONCRETE PAVEMENTS WITH PNEUMATIC ROLLERS HAVING CONTACT PRESSURES SIMILAR TO THAT OF THE ROLLING STOCK ON THE HIGHWAYS. RESULTS SHOWED THAT IN ADDITION TO HIGH CONTACT PRESSURES, THE OPTIMUM NUMBER OF PASSES WITH THE PNEUMATIC ROLLER IS ESSENTIAL IN OBTAINING HIGH INITIAL COMPACTION THEREBY REDUCING THE MAGNITUDE OF LONGITUDINAL GROOVES OVER A PERIOD OF TIME. PERIODIC SURVEYS INDICATED /1/ THAT MOST OF THE INCREASE IN COMPACTION OCCURS DURING THE FIRST 6 MONTHS OF TRAFFIC AFTER WHICH TIME THIS RATE DECREASES, /2/ THAT THE 85-PSI SECTION REQUIRES THE LEAST NUMBER OF COVERAGES FOR OPTIMUM CONDITIONS AND HAS THE LEAST MAGNITUDE OF RUTTING AFTER THREE YEARS TRAFFIC, AND /3/ THAT THE VOID CONTENT AFTER ONLY 6 MONTHS OF SERVICE HAD DECREASED 1.2 PERCENTAGE POINTS BELOW THE 75-BLOW MARSHALL DESIGN VOID CONTENT INDICATING A NEED FOR HIGHER LABORATORY DESIGN COMPACTIVE EFFORT. /AUTHOR/
