THE OVERLAY OF RIGID PAVEMENTS

SOME AIRFIELD PAVEMENTS DESIGNED FOR THE LESSER LOADS OF WORLD WAR II AIRCRAFT NOW HAVE INSUFFICIENT BEARING CAPACITY FOR PRESENT USE. THE CORPS OF ENGINEERS HAS COMPLETED MANY INVESTIGATIONS TO INDICATE THE BEST METHOD OF INCREASING THE BEARING CAPACITY OF SUCH PAVEMENTS. THE MOST INTERESTING OF THESE ARE THREE PARALLEL FULL-SCALE TRAFFIC TESTS CONDUCTED AT MACDILL FIELD, FLORIDA; MAXWELL FIELD, ALABAMA; AND LOCKBOURNE AIR FORCE BASE, OHIO. THE TESTS AT THE THREE SITES WERE CONDUCTED WITH A 60,000-LB. LOAD ON DUAL WHEELS OF THE B-29 AIRCRAFT CONFIGURATION, WITH A RIGID BASE PAVEMENT 6 IN. THICK, UNCOVERED, COVERED WITH FLEXIBLE TYPES OF OVERLAY 3 TO 12 IN. THICK, AND RIGID TYPE OVERLAYS 6 TO 9 IN. THICK. THE SUCESS OF FLEXIBLE TYPE OVERLAYS WAS PRONOUNCED; INDICATING THAT THIS TYPE OF TREATMENT APPEARS TO BE THE MOST SUCCESSFUL METHOD TO INCREASE THE BEARING CAPACITY OF AN EXISTING RIGID PAVEMENT. /AUTHOR/
