Résumé
Sudan national highway network expanded too much in recent years, however, constructed roads are facing many performance failures resulting mainly from un sufficient survey of traffic and construction material. There is no enough data regarding natural material for road construction therefore this research mission started by surveying for quarries which are the main source of road material, access their material characteristics then conduct suitable design templates that can accommodate their specifications so as to become design modalities for future use. We’d divided the study area into three sectors, in each sector we’d suggested a new link road to be designed as pilot road. We’d conducted design work using input data from this research results, in addition to data from National Highway Authority (NHA) laboratories archives and traffic counts carried out on 2012 and 2016 via two well know pavement design methods ; US- AASHTO1986 and UK TRL Laboratory Report(LT1132)– (Powell et al., 1984), The final results were analyzed and at last available quarries with good granular material are determined and the best road design method had been recommended with justifications.
