STUDY OF BEHAVIOR OF BITUMINOUS-STABILIZED PAVEMENT LAYERS

A TEST SECTION WAS CONSTRUCTED WITHIN THE EXISTING MULTIPLE-WHEEL, HEAVY GEAR LOAD (MWHGL) TEST SECTION UTILIZING THE EXISTING 4.0-CBR CLAY SUBGRADE. THE FOUR TEST ITEMS WERE SUBJECTED TO TRAFFIC WITH A SIMULATED C-5A MAIN GEAR 12-WHEEL ASSEMBLY WITH A 360,000-LB GROSS LOAD AND WITH A 75,000-LB SINGLE- WHEEL ASSEMBLY. THE RESULTS OF TESTS SHOWED THAT THE PERFORMANCE OF THE BITUMINOUS-BOUND BASE AND SUBBASE MATERIALS WAS SUPERIOR TO THAT OF SIMILAR PAVEMENTS CONSTRUCTED OF UNBOUND GRANULAR MATERIALS; THE QUALITY OF AGGREGATE USED IN THE BITUMINOUS BASE COURSES HAD A SIGNIFICANT EFFECT ON PAVEMENT PERFORMANCE; AND THE GREATEST BENEFIT FROM BITUMINOUS STABILIZATION WAS IN UPGRADING THE QUALITY OF POOR-TO-BORDERLINE MATERIALS. /AUTHOR/
