Lesson 1Overview of asphalt pavement behavior and pothole formation mechanisms (fatigue, raveling, water infiltration)This part review asphalt road structure and how traffic, age, and water cause potholes, covering fatigue crack, raveling, stripping, base fail, and drainage issues so crew fit match repair to root cause.

When to use temporary emergency patchesCriteria for semi-permanent patch selectionWhen full-depth patching is requiredTraffic level and safety considerationsBudget, crew, and equipment constraintsLesson 6Effect of weather and traffic on method selection and timing (temperature limits for hot mix, rain mitigation, curing time, night vs day work)This part look at how temperature, wet, and traffic load affect repair time and method, like hot-mix temp limits, rain and freeze-thaw risk, curing need, lane close window, night vs day work.
