STRUCTURAL BEHAVIOR OF HEAVY-DUTY-CONCRETE AIRFIELD PAVEMENTS

ACCELERATED TRAFFIC TESTS HAVE BEEN COMPLETED ON TWO FULL-SCALE TEST PAVEMENTS. THE TRAFFIC LOADINGS APPLIED WERE 150,000 LB. WITH A SINGLE WHEEL AND WITH A FOUR-WHEEL OR TWIN-TANDEM-GEAR CONFIGURATION. A COMPLETE DESCRIPTION OF THE TEST PAVEMENTS FOR THE MULTIPLE OR TWIN-TANDEM-WHEEL LOADING IS PRESENTED. THE TEST RESULTS GIVEN INCLUDE THE CRACK-PATTERN DEVELOPMENT ON THESE PAVEMENTS, AS WELL AS STRAIN AND DEFLECTION MEASUREMENTS AT SELECTED INTERVALS THROUGHOUT THE TRAFFIC LOADING. THIS LATTER IS OFFICIALLY DESIGNATED AS LOCKBOURNE NO. 2 MODIFICATION, MULTIPLE-WHEEL STUDY. COMPARATIVE STRAINS PRODUCED IN A 20-IN. THICK PAVEMENT ARE GIVEN FOR THE SINGLE AND MULTIPLE LOADINGS. RESULTS OF ALL ACCELERATED TRAFFIC TESTS OBTAINED THROUGHOUT THE PROGRAM ARE SUMMARIZED ON A CHART SHOWING TENTATIVELY THE PERCENT OF DESIGN THICKNESS REQUIRED FOR A GIVEN NUMBER OF LOAD REPETITIONS. /AUTHOR/
