In view of the rapid increase in mobility, the road network is associated with potential hazards and is in need of rehabilitation. Improper drainage, along with age-related wear and tear of the roads, is one of the main reasons that can lead to the deterioration of the road network.
Due to limited public funds, it is becoming increasingly difficult to keep all roadways in good and safe condition for traffic.
Drainage systems are used to absorb and drain surface water e.g. aquaplaning and black ice, as well as water from the ground e.g. frost heave. Modern drainage systems (drainage) require durability, high load-bearing capacity, easy handling and optimum ease of maintenance.
