PREDICTIVE DESIGN PROCEDURES, VESYS USERS MANUAL--AN INTERIM DESIGN METHOD FOR FLEXIBLE PAVEMENTS USING THE VESYS STRUCTURAL SUBSYSTEM

This manual has been written to provide the pavement manager and design engineer with a ready reference of procedures to predict the structural responses and hence the integrity of flexible pavements. A pavement section of known geometry is chosen, and its behavior over time is predicted by sets of mechanistic models which have been computer programmed. The computer program package known as the VESYS System computes pavement response, distress, and serviceability. Results of the analysis must be compared with sets of decision criteria imposed by the user agency. The analysis process is repeated until the computed levels of pavement behavior over a specified lifetime, meet the established design criteria. The manual is developed so that it can be used with a minimal amount of reference to other materials, however, supporting references are provided throughout and these should be consulted for a better understanding of the methods and concepts presented. As new information and test procedures become available, and refinements are made to the analyses procedures, updated references will also be distributed to replace or be added to the current information. /FHWA/
