The current ODOT overlay design procedure sometimes indicates additional pavement thickness is needed right after the overlay construction. Evaluation of the current procedure reveals that using spreadabiity to back calculate existing pavement modulus for both flexible, rigid, and composite pavements could lead to substantial errors. Spreadability
