Comparisons between Measured and Predicted Flexible Pavement Responses
A linear three layer viscoelastic computer program VESYS I was utilized to predict the surface deflections at, 70F, of two flexible pavement geometries for both static and dynamic loading conditions. Linear elastic, non-linear elastic and linear viscoelastic type laboratory tests were conducted on the layer component materials to determine the appropriate material properties of each material for input to the computer programs. An iterative technique VESYS I W/ITERATION was devised which also made it possible to compute the pavements responses when the subgrade material is assumed non-linear elastic. Such an analysis may be termed pseudo non-linear viscoelastic. The computed pavement responses were then compared with responses which were measured during the testing of two prototype flexible pavements at 70F subjected to static and dynamic loading conditions. The results indicated the potential use of viscoelastic multi-layer theory to account for rutting in flexible pavements.
