摘　　要：坦桑尼亚FD项目于2014年7月20日完工,由于路面沥青混凝土采用Superpave法进行配合比设计,车辙试验满足6万单趟时车辙深小于4mm的合同规范规定,并精心施工。通车5年来,振动带基本完好,证明道路质量优良,对沥青混凝土原材料、设计、施工加以总结,为后续类似道路施工提供参考。FD road project in Tanzania was completed on 2014-07-20.the road surface asphalt concrete(AC)was designed by Superpave Mix Design,the RDw is less than 4 mm/60000 passes by Wheel Tracking Test according to contract specification.The project was carefully constructed.After 5 years of opening to traffic,the rumble strips is almost as same as the original shape,which can prove that the quality is good.Now we summarize the asphalt concrete material’s properties,Superpave Mix Design and construction for the reference of the similar overseas projects.
