Strengths

  • +Addresses a critical need for improved pavement design.
  • +Proposes a move towards more rational and performance-based design.

Limitations

The complexity of real-world pavement behaviour can be difficult to fully capture in a model.

Reliability & validity

Reliability would be assessed by repeating simulations with identical parameters. Validity would be addressed by comparing simulation results to known pavement performance data or established engineering principles.

Think critically

How can the complexity of environmental factors (e.g., freeze-thaw cycles, moisture content) be accurately integrated into pavement design models to further enhance longevity?
