LOAD-DEFLECTION STUDY OF SELECTED HIGH TYPE FLEXIBLE PAVEMENT IN MARYLAND

A COOPERATIVE PROGRAM OF LOAD-DEFLECTION TESTS OF SEVERAL HIGH-TYPE FLEXIBLE PAVEMENTS IN MARYLAND WAS INAUGURATED IN THE SPRING OF 1955. A SINGLE TEST CONSISTED OF THE APPLICATION OF A SLOWLY MOVING 11,200-LB WHEEL LOAD OF A SINGLE-AXLE TRUCK TO AN ARBITRARILY SELECTED POINT ON THE PAVEMENT AND THE MEASUREMENT OF THE RESULTING PAVEMENT DEFLECTION AND REBOUND. MEASUREMENTS WERE MADE AT A POINT BETWEEN THE DUAL TIRES BY MEANS OF THE PAVEMENT-DEFLECTION INDICATOR KNOWN AS THE BENKELMAN BEAM. TESTS WERE MADE IN THE SPRING AND IN THE FALL AT APPROXIMATELY 1,000 MARKED LOCATIONS OVER A DISTANCE OF ABOUT 85 LANE MILES. THE PAVEMENTS TESTED RANGE IN AGE FROM TWO TO ELEVEN YEARS AND ARE IN EXCELLENT CONDITION. THE REPORT CONTAINS A DESCRIPTION OF THE PAVEMENTS STUDIED, THE TEST PROCEDURE USED, AND THE RESULTS OF THE TESTS CONDUCTED TO DATE. /AUTHOR/
