Surface Distress Index (SDI)

A measure that was developed by the New Jersey Department of Transportation to support pavement treatment selection and long-term analysis. Surface Distress Index uses observation of surface distresses to rate pavement conditions. It is a composite index that considers structural and nonstructural distress that can be observed at the pavement surface, including cracking, patching, shoulder deterioration, shoulder drop, faulting, joint deterioration, and running.
