Scoring

CCI

Definition

Cracking Condition Index (RT-CCI). A 0-100 score built primarily on ASTM E3303, computing aperture-weighted cracking indices from digital imagery. Uses AASHTO R 55 width-based severity classification (Low below 6mm, Medium 6-19mm, High above 19mm). Isolates crack-specific condition from the full distress set. Applied to both asphalt and concrete.

In context

An agency focused on sealing cracks before they spread may track CCI cycle over cycle.
