Session Title

2020 ATL Pavement Design Case Study

Track Title

Pavements

Event Description/Abstract

Four projects on I-65 were selected, designed, and constructed as 2020 ATL (added travel lanes) projects. During the pavement design stages, six alternatives with MEPDG (Mechanistic Pavement Design Guide) analysis, cost (per lane miles), and LCCA (life cycle cost analysis) were considered. Ultimately all projects were selected to be total reconstruction with an alternate bid (HMA vs. concrete) in anticipation of a lower bidding cost. In the end, INDOT saved 14% on these projects ($200M total cost). In this session we will describe various alternate pavement design analyses with cost analysis.
