PCI and IRI improvements 2. Correct for deterioration (Age) Introduction & Methodology: Maintenance activities impact on pavement condition STEPS: 1. Data Validation 2. Candidate Selection 3. Activity-Condition Assimilation 4. Activity Summary 5. Activity Condition Summary Project Length: 1.0 mi Project Length: X mi Project cost: $210,000 Project cost: $X Section Length: 0.5 mi Section Length: X mi Section A: Multiple activities. Discontinue analysis. Section B: Single activity (#2). Continue analysis. Conclusions: 1. Maintenance activities extend pavement life 2. Integrate with pavement management system (dTIMS) 3. More data needed to validate the results Intersecting Segment Length: 0.5 mi 0.4 mi 0.1 mi Total Project Length: 1.0 mi 1.0 mi Null Total Project Cost: $210,000 $210,000 Null History Section ID: Null B B Proportional Project Cost: NA (0.4/1.0 )*$ 210K NA =$84,000 History Section Coverage: NA 0.4/0.5=80% NA
