FLEXIBLE PAVEMENT DENSITY: THREE STUDIES

THE FIRST STUDY REPORTED A CHANGE IN THE DENSITY AND ITS VARIABILITY IN ALL PAVEMENT COURSES DURING SUCCESSIVE PHASES OF CONSTRUCTION AND AFTER A PERIOD UNDER TRAFFIC. THE SECOND STUDY DETERMINED THE INFLUENCE OF VARIOUS NUMBERS OF STEEL-WHEEL ROLLER PASSES ON PAVEMENT DENSITY. THE PAVEMENT WAS RESAMPLED AFTER 3 YEARS TO DETERMINE THE CHANGE IN DENSITY RESULTING FROM A LIMITED AMOUNT OF TRAFFIC. IN THE THIRD STUDY, INITIAL PAVEMENT PROPERTIES (PERCENT OF AIR VOIDS AND ASPHALT CONTENT) WERE INVESTIGATED TO DETERMINE THEIR EFFECTS ON PERFORMANCE. ONE PARTICULAR PAVEMENT, CONSTRUCTED IN LATE-SEASON COOL WEATHER, WAS STUDIED TO FIND THE CAUSE OF ITS PREMATURE FAILURE. /AUTHOR/
