Streets Pavement Maintenance Program Update Presentation

Streets Pavement 
Maintenance Program

The Big Picture
•
Chandler maintains ≈ 2,090 lane miles 
(LM) of streets 
•
Current overall Pavement Quality 
Index (PQI) = 65.8 (out of 100)
•
Aspirational goal = 70  Baseline = 65 
•
Higher funding is needed to hold the 
line and/or improve

Rating system is Pavement Quality Index (PQI) 
PQI Scale  1–100 (100 = best) 
PQI calculation criteria:
Surface Distress Index (SDI) → PCI* equivalent
Ride Comfort Index (RCI) 
Structural Adequacy Index (SAI)
Measured every 4-5 years by consultant
Most recent survey completed Nov. 2023 for FY 2024-25
How We Measure Pavement Condition
*PQI is stricter than the common Pavement Condition Index (PCI) scale used by most cities

Chandler:  PQI analyzes the quality and performance of roadway sections 
Another Measurement: PCI concentrates heavily on the surface condition

Chandler’s overall average PQI today = 65.8
Chandler’s SDI (PCI equivalent) overall average = 74.7

Chandler vs. Neighboring Cities
*Pavement Condition Index (PCI) scores look better because the scale is less strict

Typical Lifecycle 
of Chandler Roadway Sections
The untreated life expectancy of a roadway is 20-25 years
Can be impacted by construction quality, traffic loads, weather, oxidation & sun
Year 0 → New construction or full repave (+ ADA upgrades) 
Year 1–3 → Rejuvenator coat 
Year 3–7 → 1st Seal coat 
Year 8–14 → Slurry seals (every 5–7 years) 
Year 15–25+ → Continued preservation or major repave again
Goal               Intervene early and often to avoid expensive reconstruction

Treatment Toolbox & Triggers
Asphalt Repave + ADA       Slurry Seal and/or Asphalt Patch       Rejuvenator or Surface Seal

Slurry Seal or 
Asphalt Patch
$30k – $60k

Asphalt Repave
(Mill & Overlay) + ADA
$150k – $250k+

What Drives the Highest Costs?
ADA Improvements
Annual Cost $10M
Mill and Overlay
Annual Cost $21M
(Varies based on RoadMatrix data scenario)
• ADA - Mandated curb ramp & sidewalk upgrades are required on every 
Mill & Overlay project 
• ADA now consumes  ~ 1/3 of the repaving budget
• Typical split (FY 2023-24 actuals):

Annual Preservation Treatments 
FY 2024-25 Averages   –   These low-cost treatments keep good roads good
Slurry Seal
$1.0M (approx. 32 LM)
Crack Seal
$0.66M (approx. 900K linear ft) 
Emulsion Surface Seal 
$1.0M (approx. 29 LM)
Rejuvenator Seal 
$0.4M (approx. 24 LM)

Same dollars buy far fewer lane miles

Recent Progress
PQI Trend (3-year rolling average) 
2016 → 59 (low point) 
2019 → 69.5 (peak) 
2023 → 61.0 
2024 → 64.5 
2025 → 65.8 ↑
$30M in one-time General Fund additions
(FY 2023–2026) has moved the needle

Path Forward
To maintain or enhance current PQI (65.8): 
→ Need approximately $5M/year 
General Fund support on top of existing 
Bonds and HURF in CIP
To reach and hold aspirational PQI 70: 
→ Requires sustained higher investment 
(HURF + Bonds + General Fund)
2025 Voter Approved Street Bond program = 
$12.1 M per/year — a strong start

In Summary
•
Chandler’s roads are fair (PQI 65.8) but will 
decline without more funding
•
Early preservation is 5–10× cheaper than 
reconstruction
•
ADA requirements and inflation have 
significantly raised costs
•
Recent funding increases are helping — 
continued investment is critical
