A STATEWIDE DEFLECTION STUDY OF CONTINUOUSLY REINFORCED CONCRETE PAVEMENT IN TEXAS

A PERFORMANCE STUDY OF CONTINUOUSLY REINFORCED CONCRETE PAVEMENT WAS CONDUCTED IN TERMS OF LOAD-DEFLECTION STUDIES. THE FOLLOWING FACTORS AFFECTING PAVEMENT PERFORMANCE WERE CONSIDERED' /1/ SUBGRADE SUPPORT, /2/ SUBBASE TYPE, /3/ CONCRETE MODULUS OF ELASTICITY, /4/ CONCRETE MODULUS OF RUPTURE, /5/ PAVEMENT THICKNESS, /6/ SEASON OF THE YEAR, AND /7/ SOIL MOISTURE CONDITION. THE EFFECT OF EACH OF THE FACTORS ON DEFLECTION AND STRESS OR CURVATURE WAS STUDIED. THE VARIABLES THAT SIGNIFICANTLY AFFECT DEFLECTION AND RADIUS OF CURVATURE ARE CORRELATED INTO MODEL EQUATIONS. THE CONSTANTS IN THE EQUATIONS WERE DETERMINED FROM THE DATA USING MULTIPLE REGRESSION TECHNIQUES. SOME INITIAL ASSUMPTIONS MADE IN THE DESIGN AND DEVELOPMENT OF CONTINUOUSLY REINFORCED CONCRETE PAVEMENT FOR TEXAS CONDITIONS WERE VALIDATED. /AUTHOR/
