Due to problems with bidding, specifications and quality control, the practice of thin bituminous surfacings is declining in Ethiopia in favour of asphalt concrete. This is leading to an unnecessarily expensive surfacing being used on roads where a thin bituminous surfacing is sufficient to resist traffic abrasion. In order to solve this issue, a series of training courses have been developed and implemented with the intention of reviving skills in the design, construction and maintenance of thin bituminous surfacings. Three groups of practitioners have been involved in the training courses; operators and foremen, technicians and engineers. It is intended that these training courses will fit into the existing training and education system in Ethiopia.
