MONTHLY VARIATIONS IN PAVEMENT DEFLECTION, REFERENCE SECTIONS IN RIO DE JANEIRO STATE

DATA COLLECTED IN THREE REFERENCE SECTIONS OF RIO DE JANEIRO STATE ARE PRESENTED. MEASURES ARE TAKEN MONTHLY OF THE DEFLECTION WITH THE BENKELMAN BEAM ON THE TRACKS OF EXTERNAL AND INTERNAL WHEELS. THE OBTAINED DATA ARE TREATED STATISTICALLY AND THE MONTHLY CHARACTERISTIC DEFLECTION OF EACH SECTION IS CALCULATED. IT WAS VERIFIED THAT THE CHARACTERISTIC DEFLECTION VARIES WITH THE RAIN PRECIPITATION. FROM THIS FACT A METHOD IS SUGGESTED FOR THE EVALUATION OF PAVEMENT DEFLECTION IN THE WORST RAIN CONDITIONS, FOR DIMENSIONING PAVEMENT REINFORCEMENT. /RRI/
