METHODS OF DESIGNING THICKNESS OF FLIGHT STRIPS AND AIRPORT RUNWAYS FOR WHEEL LOADS EXCEEDING 10,000 LB.

THREE SECTIONS OF PAVEMENT ARE CONSTRUCTED. THE THICKNESS OF THE FIRST IS THAT ESTIMATED TO BE NECESSARY FOR THE WHEEL LOADS IN QUESTION BY ANY DESIRED METHOD, SUCH AS USED BY THE ARMY, THE NAVY, OR BY THE USE OF SOIL BEARING TEST DATA. THE THICKNESS OF THE SECOND IS 50 PERCENT GREATER, AND OF THE THIRD 30 PERCENT GREATER THAN THAT ESTIMATED. THE THICKNESS NECESSARY TO SUPPORT THE DESIGN LOAD FOR A SPECIFIED DEFLECTION IS OBTAINED BY PLOTTING THE THICKNESS OF THE TRIAL SECTIONS AGAINST RECORDED DEFLECTIONS. THE SUCCESS OF THE METHOD IS LARGELY DEPENDENT UPON THE CORRECT EVALUATION OF THE LOAD BEARING TEST DATA. IN MANY CASES, DUE TO INADEQUATE CONSTRUCTION COMPACTION OF THE SUBGRADE AND PAVEMENT COURSES, A LARGE PORTION OF THE INITIAL LOAD SETTLEMENT MAY BE DUE TO MERE CONSOLIDATION OF THE COMPONENT PARTS OF THE STRUCTURE. THE METHOD MAKES IT POSSIBLE TO CONSIDER THE TOTAL SETTLEMENT OR ONLY THAT PORTION OF THE SETTLEMENT WHICH IS OF PRIMARY IMPORTANCE AS FAR AS THE ULTIMATE LOAD CARRYING CAPACITY OF THE STRUCTURE IS CONCERNED. /AUTHOR/
