How to prioritize pavement maintenance and investments across 1,100 km using objective, risk-based criteria?

Context

CD22 manages a 1,100 km road network in Côtes-d’Armor. Data was spread across tools and local know-how, making annual investments hard to justify and prioritize. Oxand helped centralize the pavement inventory, model aging and risk, and simulate scenarios to forecast multi-year budgets and reduce maintenance backlog exposure.

What did we do?

  • Collected and consolidated pavement data via questionnaires and workshops
  • Built functional breakdown and tailored aging & risk models for road sections
  • Parameterised maintenance actions and cost curves, then loaded data into Simeo
  • Ran scenario simulations to compare end-of-period risk and define budget envelopes

Gains
