PROJECT APPROACH DATA COLLECTION TO DETERMINE THE UNSURFACED ROADWAY CONDITION INDEX (URCI)

CRREL Developed the URCI in the Late 1980s and Early 1990s

The URCI is a Comprehensive Statistical Index of Road Conditions Based on Variables Observed During Seasonal Windshield Surveys and Annual Criteria Measurements

The URCI is Calculated from Deduct Values Tabulated by a Prioritized List of Seven Measured Roadway Distresses

PROJECT APPROACH ELEMENTS OF THE URCI The Seven Distresses Used to Calculate the URCI:

1. Improper Cross Section

2. Inadequate Roadside Drainage

3. Corrugations

4. Dust

5. Potholes

6. Rutting

7. Loose Aggregate

A Statistical Study Determined that the URCI Value is Repeatable and the Methodology was Tested and Verified at Seven Locations from Alaska to New England
