FLEXIBLE PAVEMENT OVERLAY DESIGN DEFLECTION OF PAVEMENT SECTION IN ADDITION TO THE SEASONAL VARIATIONS, THE DEFLECTION OF A PAVEMENT SECTION MAY VARY ALONG ITS LENGTH. TO REDUCE THE EFFECT OF BOTH VARIABLES, A STATISTICAL PROCESS IS USED WHEN ESTIMATING THE MAXIMUM DEFLECTION. • DIVIDE THE PAVEMENT INTO SECTIONS WHICH ARE 300M LONG. THE SECTIONS CAN BE OF VARIABLE LENGTH PROVIDED THEY ARE HOMOGENEOUS WITH RESPECT TO THE FACTORS WHICH INFLUENCE THE PAVEMENT DESIGN (E.G., SUBGRADE AND TRAFFIC) • SELECT AT LEAST 10 STRATIFIED TEST POINTS WITHIN EACH SECTION USING A TABLE OF RANDOM NUMBERS • OBTAIN THE DEFLECTION MEASUREMENT AT THE SELECTED TEST POINTS USING THE FALLING WEIGHT DEFLECTOMETER • CALCULATE THE AVERAGE DEFLECTION (X) AND THE STANDARD DEVIATION (σ x ) • CALCULATE THE ESTIMATED MAXIMUM PROBABLE DEFLECTION VALUE D max = ( X + 2σ x ) WATCH FOR OUTLIERS (LOCAL REPAIR), ADJUST FOR SEASON, SPRING ~ 1.5 x FALL, CONVERT TO STATIC (BENKELMAN BEAM EQUIVALENT), BENKELMAN BEAM ~ 1.5 X FWD
