DEFLECTION STUDIES PERFORMED ON EL CENTRO ROAD (03-SAC-99) TEN YEAR REPORT

THE PERFORMANCES OF THREE STRUCTURAL SECTIONS CONSTRUCTED OVER HIGHLY RESILIENT SOILS ARE EVALUATED BY BENKELMAN BEAM DEFLECTION MEASUREMENTS AND BY VISUAL OBSERVATIONS OF SURFACE FATIGUE. THE STRUCTURAL SECTIONS WERE DESIGNED TO REDUCE DEFLECTIONS TO TOLERABLE LEVELS. DEFLECTION MEASUREMENTS WERE MADE AT VARIOUS STAGES OF CONSTRUCTION AND ANNUALLY OVER A TEN YEAR PERIOD AFTER CONSTRUCTION. ALL THREE STRUCTURAL SECTIONS, RESISTED SURFACE FATIGUE SATISFACTORILY EVEN THOUGH DEFLECTION MEASUREMENTS WERE HIGHWER THAN THE DESIGN MAXIMUM DEFLECTIONS. THE EFFECTS OF MOISTURE CONTENT AND TEMPERATURE CONDITIONS ON DEFLECTION MEASUREMENTS ARE ALSO DISCUSSED. /AUTHOR/
