A NEW TEMPERATURE-CORRECTION PROCEDURE FOR BENKELMAN-BEAM REBOUND DEFLECTIONS

THE TEMPERATURE SUSCEPTIBILITY OF BENKELMAN-BEAM DEFLECTIONS MADE ON THICK SECTIONS OF ASPHALT BASES AND SURFACING HAS BEEN THE SUBJECT OF AN INTENSIVE STUDY. IN ORDER FOR DEFLECTION TO BE A USEFUL DESIGN TOOL IN EVALUATING OLD PAVEMENTS AND IN THE DESIGN OF OVERLAYS, THEY MUST BE REFERENCED TO A STANDARD TEMPERATURE. A NEW PROCEDURE IS PRESENTED FOR CORRECTING BEAM DEFLECTIONS MADE ON TREATED AND UNTREATED PAVEMENT BASES. THE PROCEDURE IS BASED ON FIELD STUDIES IN WHICH DEFLECTION HAS BEEN MEASURED AT PREDETERMINED LOCATIONS THROUGHOUT 24-HOUR PERIODS WHEN TEMPERATURES WERE FLUCTUATING WIDELY. IN ADDITION TO THE FIELD STUDIES REPORTED HERE FOR THE FIRST TIME, STUDIES PREVIOUSLY REPORTED BY OTHER RESEARCH AGENCIES ARE USED IN THE DERIVATION OF THE PROCEDURE. /AUTHOR/
