COURSE CONTENTS

  1. To study the physical properties of bitumen (i.e. Penetration test (ASTM D5 | AASHTO T49), ductility (ASTM D113 | AASHTO T51 | ASTM D6084), softening point (ASTM D36 | AASHTO T53), flash and fire point (ASTM D92), breaking point (EN 12593) etc.).
  2. To determine the physical properties of aggregates (i.e. Aggregate size and shape (ASTM C136 | C136M), abrasion (ASTM C131), specific gravity (ASTM C127-15 | AASHTO T85-91), impact value (ASTM D5874) etc.).
  3. To determine marshal stability (ASTM D6927), flow test (ASTM D6927) and CBR of bitumen and asphalt mixtures (ASTM D1883).
  4. To study (through literature) the effect of modifiers in cement/bitumen/asphalt mixtures for flexible and rigid pavements and their failure mechanism using SEM (ASTM C1723-10).
  5. Study to find the level of service, signal timing for an intersection and traffic flow.
  6. Non-destructive testing of pavements.
  7. Site visit to study flexible and rigid pavement failures.
  8. Design of flexible and rigid pavements (including study of horizontal, vertical,
    transition curves and super elevation) using software.
