Description

Course Description

A road construction and maintenance worker is part of the construction of roads, bridges, railways, pavements, etc. Apart from building new road sections, they are also in charge of reconstruction of old and worn out sections. The amount of work they have increases in spring, when the roads need to be repaired from the use of salt and sand. During the winter, they are hired to clean the roads so that the traffic would continue normally. Also, one of their duties is cleaning roads after landslides or other inconveniences. The workers are trained for occupational health and safety as well, so as to be prepared to adequately protect themselves and other people.

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.
