TRAFFIC TESTING OF OVERLAYS ON RIGID AIRFIELD PAVEMENTS

THE OFFICE, CHIEF OF ENGINEERS WAS, IN 1944, CONFRONTED WITH THE PROBLEM OF REINFORCING A NUMBER OF AIRFIELDS FOR INTENSIVE USE BY AIRPLANES OF THE B-29 CLASS. SINCE SUFFICIENT DATA WERE NOT AVAILABLE FOR FORMULATING CRITERIA FOR OVERLAY DESIGNS, A TEST PROGRAM WAS INAUGURATED TO DEVELOP THE REQUIRED DATA. AT MAXWELL FIELD, ALABAMA, OVERLAYS ON A 6-IN. CONCRETE PAVEMENT ON PLASTIC SUBGRADE WERE TESTED UNDER TRAFFIC. AT MACDILL FIELD, FLORIDA, SIMILAR TRAFFIC TESTS WERE MADE ON OVERLAYS CONSTRUCTED ON ON 6-IN. CONCRETE PAVEMENT OVER A UNIFORM SAND SUBGRADE. TRAFFIC ON THE TEST SECTIONS CONSISTED OF A SPECIALLY CONSTRUCTED UNIT PRODUCING A LOAD OF 60,000 POUNDS ON A B-29 DUAL WHEEL ASSEMBLY. /AUTHOR/
