Building the capacities of local road contractors


Thin bituminous surface treatments are used for surfacing newly built roads with light to medium traffic, and can also be used to maintain roads with heavy traffic. The key purpose of such surface treatments is to give a skid-resistant, dust-free and waterproofing layer to the road surface, and to prevent damages. Despite this benefit, bituminous surface treatment is a declining practice in Ethiopia in favour of the more common asphalt concrete form of construction.

Asphalt concrete is however considerably more expensive than surface dressing particularly for low traffic rural roads. Hence, the idea of restoring confidence in road bituminous surface treatments through capacity-building and training of road contractors and operators.
