Seasonal variation in flexible pavement deflections
Mathematical model to relate flexible pavement deflections to single-axle load, thickness of pavement components, and time; plotting creep speed deflection vs time for AASHO Road Test data reveals higher deflections in spring than in winter; this behavioral pattern is described by sine wave of constant amplitude oscillating about displaced horizontal base line; assumptions of constant amplitude and horizontal base line are substantiated by data taken over 10 yr period from seven highways in Maryland; amplitude of wave and level of base line are determined as functions of thickness index and applied single-axle load.
