STANHOPE STUDY OF COMPACTION METHODS FOR BITUMINOUS STABILIZED BASE
IN SEPTEMBER 1970 THE EQUIPMENT COMMITTEE OF THE NEW JERSEY DEPARTMENT OF TRANSPORTATION CONDUCTED ITS THIRD MAJOR EVALUATION TEST OF COMPACTION EQUIPMENT FOR BITUMINOUS CONCRETE. THE OBJECTIVE OF THE TEST WAS TO EVALUATE THE COMPACTION CAPABILITIES OF 2 VIBRATORY ROLLERS AND A TANDEM ROLLER AND TO COMPARE THEM WITH THE CAPABILITIES OF THE DEPARTMENT'S STANDARD COMPACTION SYSTEM (3-WHEELED ROLLER WITH TANDEM FINISH). COMPARISONS WERE MADE BY USING BOTH MULTIPLE- AND THICK-LIFT PAVING METHODS. THE FINDINGS INDICATED THAT ALL ROLLERS EVALUATED WERE CAPABLE OF ACHIEVING ACCEPTABLE DENSIFICATION LEVELS IN THE STONE MIX, BITUMINOUS STABILIZED BASE COURSE USED IN THE TEST CONSTRUCTION. IN MULTIPLE-LIFT CONSTRUCTION THE VIBRATORY COMPACTORS WERE FOUND TO ATTAIN ESSENTIALLY THE SAME BASE DENSITY AS THAT PRODUCED BY THE DEPARTMENT'S STANDARD SYSTEM. HOWEVER, THE VIBRATORY UNITS REQUIRED APPROXIMATELY 30 PERCENT MORE COMPACTION TIME. IN THICK-LIFT CONSTRUCTION THE DEPARTMENT'S SYSTEM WAS AGAIN FOUND TO BE THE OPTIMUM OF THE ROLLER SYSTEMS CONSIDERED. THE VIBRATORY ROLLERS WERE NOT OBSERVED, WITHIN THE RANGE OF APPLICATIONS EVALUATED, TO CAUSE DECOMPACTION OR DENSITY DROP OFF OF THE BASE MATERIAL. PAVEMENT RIDING QUALITY WAS NOT ADVERSELY AFFECTED BY EITHER ONE OF THE VIBRATORY COMPACTORS STUDIED. /AUTHOR/
