Letter of the Day | Patching potholes not enough, we must understand why roads fail

THE EDITOR, Madam:

Anyone who drives on Jamaica’s roads has likely experienced the frustration of seeing the same pothole repaired more than once. A few months later, or sometimes after a heavy shower of rain, it reappears. This raises an important question: are we addressing the underlying causes of road deterioration or only repairing the visible damage?

Before a pothole is repaired, it is useful to ask why the road failed. Was poor drainage allowing water to weaken the pavement? Was the road constructed on unstable ground? Has heavy truck traffic exceeded the road’s design capacity? Or, has the pavement simply reached the end of its service life?

Understanding the cause of failure helps engineers select the most appropriate repair method. Where the underlying problem is identified and addressed, repairs are more likely to last longer and provide better value for money. If the root cause is not identified, repairs may provide only temporary improvement while the underlying problem remains.

Road maintenance is about more than filling potholes. Each damaged section of road provides valuable information that can help improve future designs, maintenance practices, construction methods, and material selection.

This process is often described as organisational learning, where experience and evidence are used to improve future decisions. By investigating failures, documenting their causes, and applying the lessons learned to future projects, road agencies can continually strengthen maintenance programmes and improve the long-term performance of the road network.

As Jamaica continues to invest in its road infrastructure, understanding the causes of pavement deterioration can help ensure that maintenance resources are used effectively and that investments deliver the greatest possible long-term value.

The public benefits from roads that are safer, more durable, and provide good value for money. A pothole is more than a defect in the pavement. It is also an opportunity to understand how and why the road deteriorated. By learning from each failure before carrying out repairs, we can support better maintenance decisions and contribute to a stronger and more resilient road network for the future.
