The use of thin bituminous surfacings for rural roads in Ethiopia has declined in recent years in favour of asphalt concrete (AC). This is due to a lack of industry confidence in thin bituminous surfacings caused by issues with bidding, project specifications and quality control. AC surfacing has thus been specified on roads where a cheaper thin bituminous surfacing would have provided an adequate and sufficiently durable seal. Therefore a training programme has been developed and implemented with the aim of restoring industry confidence in thin bituminous surfacings and to develop the skills in Ethiopia. The objective of the project was also to provide the Ethiopian Roads Authority (ERA) with the means to develop and deliver similar training courses in the future.
