The expanded polystyrene (EPS) method has been used for backfills for bridge abutment in Korea since 1993. However, the performance of EPS embankment after construction and its effect on the pavement has not been evaluated yet. In the present paper, flexural strain levels, which pavement may experiences from impulse loads, were investigated using a series of falling weight deflectometer tests. Much larger deformation and flexural strain were identified at pavement on EPS by impulse load. Based on the results, it is inferred that pavement laid on EPS embankment may experience significant repetitive deflection, and which could be one of major factors to cause fatigue damages of pavement structures under repetitive traffic loads.
