COMPACTION OF ASPHALT CONCRETE PAVEMENTS

A THORUGH LITERATURE REVIEW, A FIELD STUDY OF 15 SELECTED SITES AND A LABORATORY TESTING PROGRAM WERE CONDUCTED IN AN ATTEMPT TO DEFINE THE VARIABLES AFFECTING THE LONG-TERM DENSITY (UNDER TRAFFIC) OF ASPHALTIC CONCRETE PAVEMENTS. A MAJOR FINDING IS THAT DENSITIES OBTAINED IN THE FIELD ARE MUCH LOWER THAN THE DENSITIES OF LABORATORY COMPACTED SPECIMENS. IN CONTRAST TO LITERATURE REPORTING THAT STABILITY IS RELATED TO DENSITY, THE RESEARCHERS PRESENT DATA WHICH INDICATES THAT SUBSEQUENT DENSIFICATION UNDER TRAFFIC HAS LITTLE RELATIONSHIP TO FIELD COMPACTION EFFORT. TEST SECTIONS ARE RECOMMENDED AS PART OF PAVING CONTRACTS TO IMPROVE FIELD COMPACTION PROCEDURES. /FHWA/
