Pavement Condition Index (PCI) is a 0-100 numerical rating of pavement surface condition based on a visual survey of distress types, calculated per ASTM D6433. A PCI of 100 represents pavement in perfect condition, while lower scores reflect the type, severity, and extent of distresses observed. PCI gives road owners an objective, repeatable measure of network condition that drives when and how each section should be treated.
Key points
- PCI is a 0-100 rating where 100 is perfect pavement and 0 is failed
- It is derived from a visual survey of distress types, severities, and extents per ASTM D6433
- PCI is objective and repeatable, so sections and survey years can be compared
- PCI bands map to treatment windows - preventive maintenance is cheap at high PCI
- Survey vendors typically deliver PCI results as spreadsheets for import into your asset system
Example
Scenario: A road section is surveyed and assigned a PCI of 63, which falls in the fair band.
Result: A PCI of 63 means the section is still serviceable but trending into the window where preventive maintenance is the most cost-effective option. Common simplified bands are 86-100 good, 71-85 satisfactory, 56-70 fair, 41-55 poor, 26-40 very poor, and 0-25 serious or failed.
How PCI Surveys Work
A PCI survey follows ASTM D6433. A surveyor inspects sample units of a pavement section and records each distress by type, severity, and extent - cracking (alligator, longitudinal, transverse, block), rutting, potholes, raveling, patching, and others. Each distress reduces the score by a calculated deduct value rather than a flat amount, so a few severe potholes can hurt the score more than widespread minor cracking. The deducts are combined into a corrected value that produces the final 0-100 PCI for the section. Because the method is standardized, results are repeatable between surveyors and comparable year over year.
PCI Bands and Treatment Windows
PCI matters because cost is not linear with condition. While a section sits high in the good or satisfactory bands, cheap preventive maintenance - crack sealing, surface treatments - holds it there for years. As PCI falls into fair and then poor, the affordable preventive window closes and the work shifts to rehabilitation; once a section reaches very poor or failed, full reconstruction is often the only option and the cost per lane-kilometre rises steeply. The goal of pavement management is "right treatment, right road, right time" - spending on roads that are still cheap to save, rather than only on the ones that have already failed.
Getting PCI Data Into Your Asset System
PCI almost never originates in your asset system - a survey vendor collects it and delivers a spreadsheet keyed to road sections. The challenge is getting those scores back onto the right features without re-keying. AssetLab supports an update-mode import that matches the spreadsheet to existing road sections, writes a PCI inspection record against each one, and refreshes the condition history. The PCI value becomes the feature condition, so each survey cycle updates both the section-level detail and the average condition of the network in one import, and for O. Reg. 588/17 the average PCI of paved roads is the average condition of features in Road networks on a PCI scale.
PCI and O. Reg. 588/17 Reporting
Ontario's O. Reg. 588/17 prescribes technical levels of service for roads and bridges, including the average PCI of paved roads, the average surface condition of unpaved roads, arterial, collector and local lane-km per square kilometre of land area, and the average bridge condition index (BCI) of bridges and structural culverts. The Build Communities Strong Fund Annual Report draws on the same information.
On AssetLab's Enterprise plan, Managers and Administrators record these measures in the O. Reg. 588/17 section of Level of Service. Average road PCI, lane-km by road class and bridge and culvert BCI are computed from the networks you link, and a computed value is stored for a reporting year only when you choose to use it. AssetLab's own 0-100 condition score is not a PCI or BCI: a PCI is only computed from a road network whose condition scale is set to PCI, a declaration that the numbers loaded into it are that index. Each measure can carry ten proposed years, and the section downloads a reporting workbook. AssetLab does not prepare or file the plan, and using it does not make a municipality compliant.
