DETERMINING THE RELATIONSHIP OF VARIABLES IN DEFLECTION OF CONTINUOUSLY-REINFORCED CONCRETE PAVEMENT
A COMPREHENSIVE STUDY OF DEFLECTION IN CONTINUOUSLY REINFORCED CONCRETE PAVEMENTS HAS BEEN CONDUCTED IN TEXAS USING AASHO ROAD TEST STUDIES AS GUIDELINES FOR THE DESIGN OF THE EXPERIMENTS. LOAD AND TEMPERATURE DIFFERENTIAL, TRANSVERSE CRACK WIDTH AND SPACING /UNIQUE TO CONTINUOUSLY REINFORCED CONCRETE PAVEMENTS/, AND VARYING CONDITIONS OF SUBBASE AND SUBGRADE TYPES WERE STUDIED IN TERMS OF DEFLECTION AND RADIUS OF CURVATURE. AN EMPIRICAL EQUATION FOR ALL THESE VARIABLES WAS FORMULATED. THE DEFLECTION OF CONTINUOUSLY REINFORCED CONCRETE PAVEMENTS IS A FUNCTION OF THE LOAD APPLIED, CRACK WIDTH, CRACK SPACING, TEMPERATURE, PAVEMENT THICKNESS AND THE SUPPORTING CHARACTERISTICS OF THE SUBBASE AND SUBGRADE.
