CMAP and Applied Pavement Technology present PAVER analysis showing Addison’s network PCI at 65; staff urged to maintain preservation funding

Consultants from Applied Pavement Technology and representatives from the Chicago Metropolitan Agency for Planning (CMAP) presented the results of a PAVER pavement management study to the Village of Addison on June 2. The analysis rated Addison’s 111 center‑line miles of roadway at an area‑weighted pavement condition index (PCI) of 65 and provided multi‑year budget scenarios and treatment recommendations.

Why it matters: a PCI in the mid‑60s indicates a network where a majority of road segments can be preserved with preventive treatments, while a substantial portion remains in poor condition and will require major maintenance or reconstruction. Consultants told the committee that preservation (crack sealing, thin surface treatments) is a cost‑effective strategy to delay expensive reconstruction and that underfunding will accelerate deterioration and increase long‑term costs.

Key findings and scenarios. The consultants used a mobile data collection van to capture images and laser measurements across the street network, processed distress data through automated algorithms and verified results with trained surveyors. They reported the network average PCI of 65 and said about 60% of lane‑miles are in fair or better condition while roughly 40% are in poor or worse condition. Their modeled scenarios showed that at the village’s then‑current assumed funding (roughly $2.53 million annually with 4% escalation), the PCI will decline over 10 years. To maintain the current PCI of 65, the analysis estimated about $7.7 million per year would be required; a target PCI of 70 would require approximately $8.8 million per year.

Preservation vs. reactive repair. The presentation emphasized “preservation” treatments (crack sealing, seal coats, thin overlays) as low‑cost ways to maintain high‑condition pavements and avoid large future reconstruction costs. The consultants modeled a treatment mix and showed that allocating a portion of the budget to global surface treatments (about 20%) increases the number of lane‑miles touched each year relative to spending all funds on major maintenance and reconstruction.

Recommendations and next steps. Consultants recommended that the village maintain and operate the pavement management system (collect condition data every 3–5 years), calibrate models with local time‑series data, and adopt a preservation‑focused program that balances major M&R with preventive surface treatments. Staff present for engineering and operations received training on the system so the village can run the PAVER tool internally going forward.

Board response. Trustees and staff asked technical questions about traffic factors and calibration; consultants said functional class and traffic were considered as cofactors and that model calibration will improve as the village collects its own time‑series condition data.
