Road Maintenance Training

Category: Road Maintenance Training

Course Description

The road transport network of any country plays a vital role in its economy, and the physical condition of its infrastructure is critical. Without adequate and timely maintenance, highways and rural roads alike inexorably deteriorate, leading to higher vehicle operating costs, increased numbers of accidents, and reduced reliability of transport services.

When repair work can no longer be delayed it will often involve extensive rehabilitation, and even reconstruction, costing many times more than simpler maintenance treatment carried out earlier. The need to protect the existing network and keep it in good condition is paramount, often taking precedence over new investment.

Course Objective

The project’s objectives were to develop and improve the road maintenance management system for national and provincial roads by deploying Routine Maintenance Units (RMU) and Disaster Recovery Units (DRU) and providing training to maintenance personnel, and thereby contribute to infrastructure improvements and regional development targeting economic growth.
