Integrating Maintenance Activities into Pavement Management Systems Omar Smadi Zachary Hans Aemal Khattak Integrating Maintenance Activities into Pavement Management Systems Results: 1. 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 PCI Age 100 3 4 5 A B C D ?
