FATIGUE PROPERTIES OF CUT NEOPRENE BRIDGE BEARING PADS IN COMPRESSION

FOR THE PURPOSE OF INVESTIGATING THE LOAD-BEARING PROPERTIES OF NEOPRENE BRIDGE BEARING PADS, FOURTEEN CUT PADS, 5 X 30 INCHES IN SIZE, WERE TESTED IN COMPRESSION- FATIGUE AND EXAMINED FOR POSSIBLE STRUCTURAL DAMAGE. NINE OF THESE PADS WERE 7/8 INCH THICK AND OF 60 DUROMETER HARDNESS. MOST OF THE FATIGUE LOADING HAD A REPEATED LOAD RANGE OF 600 PSI TO 1200 PSI, A RATE OF 100 CYCLES PER MINUTE, AND WAS CONTAINED FOR ONE MILLION CYCLES, ALTHOUGH TWO TESTS WERE CONTINUED FOR TWO MILLION CYCLES. TESTS WERE CONDUCTED AT THREE TEMPERATURES; 120 F, 72 F, AND 0 F. NO PERMANENT DAMAGE WAS DETECTED AS A RESULT OF THE TESTS. /AUTHOR/
