  1. Automated Pavement Condition Surveys

  2. Typical DistressesAsphalt Concrete • Raveling • Flushing • Rippling | Shoving • Wheel Track Rutting • Distortion • Longitudinal Wheel Track Cracking • Single | Multiple • Alligator Cracking • Meaner and Mid-lane • Transverse Alligator • Centerline Alligator • Pavement-Edge Alligator • Pavement-Edge Sgl | Mple

  3. Typical DistressesPortland Cement Concrete • Raveling • Polishing • Scaling • Potholing • Joint Cracking | Spalling • Faulting • Distortion • Joint-Failure • Longitudinal Meaner Cracking • Transverse Cracking • Sealant Loss • Diagonal Corner | Edge Cracking

  4. Typical DistressesComposite • Raveling • Flushing • Spalling • Tenting | Cupping • Wheel Track Rutting • Joint-Failure • Distortion & Settlement • Longitudinal Meander Cracking • Pavement-Edge Breaking • Alligator Cracking

  5. Typical Distresses of Surface Treatment • Raveling • Flushing • Streaking • Potholing • Rippling | Shoving • Wheel Track Rutting • Distortion • Longitudinal Cracking • Transverse Cracking Multiple • Transverse Joint Reflective Cracking • Centerline Cracking Single • Centerline Cracking Multiple

  6. Condition Assessment: • Trigger treatment • Determine the extent and cost of repair • Determine a network condition index • Allow equal comparison of different pavements Data Collection: • Need data for overall decision-making • Reports distress type, severity, extent and location • Subjective/manual vs. Automated • Time Consuming | Labor Intensive | Safety Concerns

  7. Data Collection: • Protocols in use • Analog | Digital Data Processing: • Semi-Automated | Automated Data Management: • Storage | Integration | Standardization | Quality Assurance Key Aspects Technologies : • Sensor | Image | Integrated Systems

  8. Non-ContactSensor • Advantages • Monitor long-term pavement performance • Reduced inspection time • Evaluation of large areas • Does not require lane closure • Good repeatability • Disadvantages • - High initial cost • - Complex Instrumentation Systems • - Generally require operators with engineering training

  9. Image • Identification of pavement surface Fracture, Distortion and Disintegration by the means of photographing, videotaping, and digital image capturing
