ACCELERATED TRAFFIC TESTS FOR FLEXIBLE AIRFIELD PAVEMENTS
DURING 1942 AND 1943 ACCELERATED TRAFFIC TESTS WERE CONDUCTED AT EIGHT LOCATIONS ON EXISTING FLEXIBLE AIRFIELD PAVEMENTS. THE PURPOSE WAS TO SECURE PERTINENT INFORMATION RELATIVE TO THE SPECIFIC FIELDS AND, IN ADDITION, TO SUPPLY DATA USEFUL FOR GENERAL DESIGN CRITERIA. THE SUMMARY REPORT PREPARED BY THE U. S. WATERWAYS EXPERIMENT STATION FOR THESE TESTS CONCLUDES THAT: (1) WHERE A PLASTICITY INDEX VALUE IS USED AS A MEASURE OF QUALITY THE DATA INDICATE IT SHOULD BE LESS THAN 10. WHERE QUALITY IS MEASURED BY THE CBR TEST THE CBR SHOULD BE IN EXCESS OF 35 AND PROBABLY ABOUT 70, (2) GOOD COMPACTION OF THE SUBGRADE AND BASE IS ESSENTIAL TO PREVENT DETRIMENTAL CONSOLIDATION FROM HEAVY WHEEL LOADS, AND (3) CONSTRUCTON JOINTS ARE CRITICAL POINTS IN A SOIL- CEMENT BASE. /AUTHOR/
