FIELD COMPACTION STUDIES ON ASPHALTIC CONCRETE

THE RESULTS OBTAINED FROM A PROJECT UNDERTAKEN TO EVALUATE THE EFFECT OF VARYING THE COMPACTIVE EFFORT OF THE INTERMEDIATE ROLLING ON ASPHALTIC CONCRETE WERE PRESENTED. BOTH PNEUMATIC-TIRED AND STEEL-WHEEL VIBRATORY ROLLERS WERE USED ON A TOTAL OF 26 TEST SECTIONS. RESULTS OF THE TESTS MADE WITH THE PNEUMATIC-TIRED INTERMEDIATE ROLLER INDICATED THAT MAXIMUM COMPACTION IS ATTAINED WITH SIX COVERAGES, AND A SLIGHT TENDENCY FOR THE MATERIAL TO DECOMPACT WITH ADDITIONAL COVERAGES WAS NOTED. RESULTS FROM THE THREE SECTIONS IN WHICH NO INTERMEDIATE ROLLING WAS USED SHOWED THAT THE AVERAGE DENSITY ATTAINED EXCEEDED MINIMUM SPECIFICATION REQUIREMENTS. WHEN THE INTERMEDIATE ROLLING WAS OMITTED BUT TWO EXTRA COVERAGES OF THE FINAL STEEL-WHEEL ROLLING WERE APPLIED INSTEAD, THE AVERAGE DENSITY ATTAINED WAS NEARLY AS GREAT AS THE AVERAGE MAXIMUM DENSITY ATTAINED WITH THE OPTIMUM NUMBER OF COVERAGES. THE RESULTS OF PERMEABILITY TESTS INDICATE NO DETRIMENTAL EFFECT RESULTING FROM OMISSION OF THE INTERMEDIATE ROLLING. THE RESULTS OBTAINED WITH THE VIBRATORY COMPACTOR WERE INCONSISTENT AND, DUE TO THE LACK OF REPLICATION, NO EVALUATION OF THESE RESULTS WAS ATTEMPTED. /AUTHOR/
