DEFLECTION TESTS ON TEXAS HIGHWAYS

THIS PAPER PRESENTS SOME OF THE EXPERIENCES AND RESULTS OBTAINED FROM AN INVESTIGATION OF PAVEMENT DEFLECTIONS IN TEXAS. THE DATA DISCUSSED WERE TAKEN FROM MEASUREMENTS MADE BY USE OF THE BENKELMAN BEAM DURING ANNUAL DEFLECTION TESTS ON 117 MI OF FLEXIBLE PAVEMENTS. RESULTS OF LABORATORY AND FIELD TESTS ARE PRESENTED SHOWING THE RELIABILITY OF THE BENKELMAN BEAM. FACTORS WHICH MAY AFFECT THE DEFLECTION DATA ARE DISCUSSED, INCLUDING TEMPERATURE OF THE PAVEMENT SURFACE, LENGTH OF THE DEFLECTION TROUGH, FRICTION IN THE BENKELMAN BEAM AND HELMER RECORDER, AND FIELD TECHNIQUES IN THE OPERATION OF THE BENKELMAN BEAM. METHODS ARE ALSO GIVEN FOR CORRECTING THE DEFLECTION DATA FOR THESE FACTORS. /AUTHOR/
