SCI is a measure of the damage to a pavement caused by traffic and loading. Similar to PCI, it is a numerical index between 0 and 100, where 100 is the best possible condition. It is calculated using the PCI procedures defined in ASTM D5340 using a subset of the PCI distresses:
•Alligator Cracking
•Rutting
•Corner Break
•Linear Cracking
•Shattered Slab
•Shrinkage Cracking
•Joint Spalling
•Corner Spalling
