ACCELERATED TRAFFIC TESTS AT EGLIN FIELD, FLORIDA

ACCELERATED TRAFFIC TESTS WERE MADE TO SECURE FLEXIBLE PAVEMENT DESIGN DATA FOR AIRFIELD PAVEMENTS. THE TEST TRACK INCLUDED SECTIONS OF AN EXISTING AIRFIELD PAVEMENT CONSISTING OF SAND ASPHALT, SECTIONS OF ASPHALTIC CONCRETE SURFACING ON VARIABLE THICKNESS AND VARIABLE QUALITY OF SAND CLAY BASE COURSE MATERIALS, AND SIMILAR SECTIONS OF SAND CLAY BASE COURSE MATERIAL WITHOUT A WEARING COURSE. LARGE EARTH MOVING VEHICLES WERE USED TO STIMULATE AIRPLANE TRAFFIC AT 15,000, 37,000, AND 50,000 LB WHEEL LOADS. RESULTS HAVE VERIFIED THE CALIFORNIA BEARING RATIO METHOD OF DESIGN AS USED WHEN APPLIED TO FLEXIBLE PAVEMENTS PLACED ON SAND SUBGRADES. IT IS DESIRABLE TO OBTAIN A HIGH DEGREE OF COMPACTION IN COHESIONLESS SUBGRADES AND EARTH TYPE BASE COURSES DURING CONSTRUCTION IN ORDER TO PREVENT EXCESSIVE RUTTING AND ROUGHENING OF THE PAVEMENT SURFACE DUE TO TRAFFIC COMPACTION OF THE SUBGRADE. /AUTHOR/
