INDOT develops lifecycle strategies for pavement within the inventory over a 20-year horizon, using roadway condition data collected annually and uploaded into the pavement management system for evaluation.
Based on the deterioration models and triggers, INDOT software provides the optimal mix of treatment strategies that will enable the asset to achieve a state of good repair, measured by whether the asset has met our established condition target. INDOT has established a target of no more than 5% total pavement in poor condition by year 2037.

The software model provides suggestions for both an initial treatment strategy that would address the performance gaps in the short-term and a subsequent treatment or ancillary strategy. This is used to demonstrate the overall benefit to the transportation network for the length of evaluation.
After evaluating all costs and impacts, the software produces an optimal benefit-cost effective list of recommended projects, considering the programmed funding constraints against anticipated benefits across the transportation network. Outputs of the model are then evaluated and verified by INDOT roadway engineers, who incorporate their local knowledge of the pavements to approve or update the list of recommendations.
