Understanding the main causes of road pavement failures and especially premature pavement failure is crucial in determining the correct design. Why the design life is not met and various pavements including expressways are suffering from early pavement distresses? What went wrong?

Ensuring that the pavement has been properly constructed to the quality and specifications and design is key to performance and longevity of pavements and surfacing. Holdpoints for each pavement layer is essential to achieve a high standard pavement.
