DEVELOPMENT OF A PROCEDURE FOR DESIGNING PRESTRESSED AIR FIELD PAVEMENTS

SINCE 1953 THE CORPS OF ENGINEERS HAS BEEN ACTIVELY ENGAGED IN STUDIES TO DEVELOP PROCEDURES FOR THE DESIGN AND CONSTRUCTION OF PRESTRESSED PAVEMENTS FOR MILITARY AIRFIELDS. THE TWO MAJOR PHASES OF INVESTIGATIONAL EFFORT RELATIVE TO PRESTRESSED PAVEMENTS AND CRITERIA DEVELOPED FOR THE DESIGN OF SUCH PAVEMENTS ARE PRESENTED. THE INITIAL STUDY CONSISTED OF AN EXTENSIVE SERIES OF LABORATORY TESTS ON SMALL-SCALE PRESTRESSED SLABS CONSTRUCTED OF GYPSUM CEMENT. BOTH PRETENSIONED AND POST-TENSIONED SLABS WERE LOADED STATICALLY WITH LOADS SIMULATING SINGLE-WHEEL AND MULTIPLE-WHEEL GEAR CONFIGURATIONS. A COMPLETE DESCRIPTION OF THE DESIGN, CONSTRUCTION AND TESTING OF THE MODELS IS GIVEN. LOAD-MOMENT RELATIONSHIPS DEVELOPED FOR LOADINGS IN THE ELASTO-PLASTIC RANGE ARE PRESENTED FOR THE CONDITIONS REPRESENTED BY THE MODEL. THE SECOND PHASE OF STUDY WAS CONCERNED WITH THE CONSTRUCTION AND ACCELERATED-TRAFFIC TESTING OF A FULL-SCALE PROTOTYPE PRESTRESSED PAVEMENT 9 IN. THICK, 51 FT WIDE, AND 500 FT LONG. A COMPLETE DESCRIPTION OF THE TEST PAVEMENT AND THE TRAFFIC OPERATIONS IS GIVEN. USING THE SMALL-SCALE MODELS TO PROVIDE THE BASIC LOAD-MOMENT RELATIONSHIPS FOR A SINGLE STATIC APPLICATION OF THE LOAD, AND THE FULL-SCALE TRAFFIC TESTS TO PROVIDE THE DESIGN FACTORS REQUIRED FOR LOAD REPETITION, DESIGN CURVES WERE DEVELOPED FOR AIRFIELD PAVEMENTS. APPLICABILITY AND LIMITATIONS IN USE OF THE DESIGN CRITERIA ARE DISCUSSED. TYPICAL VALUES FOR DESIGN VARIABLES OTHER THAN PRESTRESSING ARE SUGGESTED. /AUTHOR/
