  1. Tennessee’s Asset Management Approach for Pavements Donald Reid DESIGN DIVISION As revised 03-08-01

  2. GASB 34 Requirements • Inventory of Pavement Assets • Condition Assessments • Management Strategies

  3. Inventory of Pavement Assets Interstate System in Tennessee • 1073 miles State Route System (non interstate routes) • Region 1: 2437 miles 154 miles divided • Region 2: 2376 miles 83 miles divided • Region 3: 3185 miles 118 miles divided • Region 4: 2687 miles 106 miles divided Continuous Inventory Updates with TRIMS Transportation Roadway Information Management System

  4. Condition Assessments Data Collection: • Infrastructure Management Services (IMS) • Data Collected: • Roughness, Rutting, Distress • Frequency: • Collect Condition Data on Interstate Every Year • Collect Condition Data on NHS Every Year • Collect Condition Data on STP 1 Region Per Year • Pavement Condition Rating: • PSI-Pavement Roughness Index • PDI-Pavement Distress Index • PQI-Pavement Quality Index
