Definition
Standard Practice for Roads and Parking Lots Pavement Condition Index Surveys. The foundational standard for pavement condition assessment, defining 19 distress types, severity classification criteria, deduct value curves, and the PCI scoring procedure. Road Triage implements all 19 distress types, severity thresholds, deduct curves, and the corrected deduct value (CDV) procedure as the core of RT-PCI scoring and the distress framework used across all five scoring methodologies.
In context
If two vendors both score to ASTM D6433, their PCI numbers can be read on the same scale.
