APPENDIX C USER'S GUIDE TO SOFTWARE FOR MODIFIED MODELS The developed alternative models for the AASHTO M-E procedure are immediately accessible to users through the use of a basic companion program to the AASHTO M-E software, specifically AASHTOWare Pavement M-E Design. The following guidelines detail how users can install this software and use it to analyze existing AASHTO M-E projects to determine the effect of slab-base interaction on pavement performance.
