摘要In recent years, research works have been heavily conducted to understand the dynamic influence on data interpretation for the road deflection measurements. For arbitrary paving system under the test load where its dynamics is important, the estimation error of the static backcalculation might be significant and would result inadequate tactics for pavement rehabilitation. In this study, the dynamic effects on steady-state deflection test are studied by comparing static and dynamic solutions from forward and backward simulations. A dynamic backcalculation program based on dynamic stress wave modeling of the Green's flexibility influence functions using versatile iterative procedures is developed to clarify the steady- state deflection test data. Post material correction procedures considering respectively the temperature and moist effects for bituminous layer and subgrade soils are suggested in this program. It is concluded that the newly developed dynamic backcalculation program can provide more reliable prediction, and that the static interpretation shall yield consistent estimation providing that the tests are conducted at relatively low frequency on sites where the bedrock effect is negligible.
