EVALUATION OF A DYNAMIC DEFLECTION DETERMINATION SYSTEM

A LANE-WELLS DYNAMIC DEFLECTION DETERMINATION SYSTEM /DYNAFLECT/ WAS EVALUATED AS A REPLACEMENT FOR BENKELMAN BEAM STATIC LOADING DEFLECTION TESTING AND AS A RESEARCH TOOL FOR DETERMINING DYNAMIC DEFLECTIONS AND ASSOCIATED ENGINEERING PROPERTIES OF PAVEMENT STRUCTURE COMPONENTS. CORRELATION STUDIES WITH THE BENKELMAN BEAM INDICATED THAT A LINEAR FUNCTION WAS SIGNIFICANT AND A COMPUTER REGRESSION ANALYSIS PROVIDED A SIGNIFICANT EQUATION. IT WAS CONCLUDED THAT THE DYNAFLECT HAS GOOD POTENTIAL AS A RESEARCH SYSTEM FOR DETERMINING STRENGTH AND PERFORMANCE CHARACTERISTICS OF PAVEMENT STRUCTURE MATERIALS, BUT THAT IS REQUIRES IMPROVEMENTS TO MINIMIZE DOWNTIME AND REDUCE TESTING TIME.
