✔ Design high-performance flexible and rigid pavements using mechanistic-empirical methods.
✔ Identify and analyze pavement distresses (cracking, rutting, fatigue, etc.).
✔ Develop cost-effective rehabilitation strategies for extending pavement life.
✔ Perform pavement life-cycle cost analysis (LCCA) for long-term investment planning.
✔ Implement sustainable and innovative pavement materials (recycled asphalt, warm mix, geopolymer concrete).
✔ Utilize advanced software for pavement performance analysis.

Course Outline:

🟢 Day 1: Advanced Pavement Materials and Properties

🔹 Overview of pavement types: Flexible vs. Rigid Pavements.
🔹 Material properties of asphalt, concrete, and base layers.
🔹 Asphalt binder and mix characteristics (Superpave, SMA, modified bitumen).
🔹 Concrete pavement components: Cement, additives, reinforcement.
🔹 Case study: Evaluating material failures in existing pavements.

🟢 Day 2: Mechanistic-Empirical Pavement Design Principles

🔹 Understanding stress-strain relationships in pavements.
🔹 Flexible pavement design using AASHTO 93, MEPDG, and IRC guidelines.
🔹 Rigid pavement design: Jointed plain, jointed reinforced, continuously reinforced concrete pavements (CRCP).
🔹 Traffic loading, climate considerations, and subgrade evaluation.
🔹 Software application: Pave3D, MEPDG, Pavement ME Design.
🔹 Case study: Designing a new pavement for a high-traffic highway.

🟢 Day 3: Pavement Distress Analysis and Rehabilitation Techniques

🔹 Identifying common pavement failures: Cracking, rutting, potholes, moisture damage.
🔹 Non-destructive testing (NDT) techniques: FWD, GPR, Profilometers.
🔹 Rehabilitation techniques for flexible pavements:

  • Overlay design (hot mix, cold mix, polymer-modified).
  • Milling and in-place recycling techniques.
    🔹 Rehabilitation techniques for rigid pavements:
  • Partial and full-depth repairs.
  • Diamond grinding and joint sealing.
    🔹 Case study: Assessing rehabilitation options for a failing road.

🟢 Day 4: Pavement Life-Cycle Cost Analysis (LCCA) and Sustainable Solutions

🔹 Economic evaluation of pavement alternatives.
🔹 Life-cycle cost analysis (LCCA) methodology.
🔹 Sustainability in pavement design:

  • Recycled asphalt & concrete materials.
  • Warm-mix asphalt & geopolymer concrete.
  • Permeable pavement for stormwater management.
    🔹 Smart pavements: Self-healing asphalt, solar roads, and IoT-integrated pavements.
    🔹 Case study: Evaluating sustainable pavement options for a highway.

🟢 Day 5: Case Study & Real-World Application

🔹 Hands-on case study: Rehabilitating an existing road section.
🔹 Group discussion: Choosing the best materials and techniques.
🔹 Presentation of rehabilitation recommendations.
🔹 Course assessment and feedback session.
