ROAD ENGINEERING

Maintenance

Of equal importance is road maintenance. Even in the worst of weather, maintenance gangs keep open the traffic routes of the country. Modern highways are designed to stand up to the stresses of heavy traffic, but all roads require regular attention. The magnitude of this work may be appreciated by the fact that maintenance cost in recent years is approximately one-third of the total highway expenditure.
